[0025] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0026] Example 1 See Figures 1 to 13This application provides an electromagnetic heating water cup with good heat dissipation effect, including a cup body 1 and a base 2. The cup body 1 includes a cup liner 12, which is made of stainless steel. The base 2 is disposed at the bottom of the cup body 1, and the base 2 is provided with an electromagnetic coil assembly 24 for heating the cup liner 12. Preferably, the electromagnetic coil assembly 24 includes a coil support 241 and an electromagnetic coil 242 disposed on the coil support 241.

[0027] Therefore, when the electromagnetic coil 242 is energized, it will generate an electromagnetic field in the upward region. This electromagnetic field can form a magnetic current at the bottom of the cup liner 12 and heat it up, thereby heating the water in the cup liner 12 to achieve boiling or heat preservation.

[0028] The base 2 is equipped with a cooling fan 22. The base 2 has several air inlets 2121 and several air outlets 2122, with the air inlets 2121 facing the cooling fan 22. Thus, under the action of the cooling fan 22, external air can enter the base 2 through the air inlets 2121 and be blown onto the electromagnetic coil assembly 24 by the cooling fan 22 to cool it. The air is then exhausted through the air outlets 2122, creating a cycle.

[0029] Therefore, by installing a cooling fan 22 inside the base 2, the electromagnetic coil 242 can be cooled in time to prevent the electromagnetic coil 242 from overheating, thereby ensuring its insulation performance and extending its service life. At the same time, it can also prevent the high temperature environment generated by the coil from affecting other electrical components inside the base 2, ensuring the normal use of the product.

[0030] Preferably, the base 2 has a circulating vortex channel, and the electromagnetic coil assembly 24 is disposed within the circulating vortex channel. The air inlet end of the circulating vortex channel is connected to the cooling fan 22, and the air outlet end of the circulating vortex channel is connected to several air outlet holes 2122. Thus, when the cooling fan 22 is turned on, external air can enter through the several air inlets 2121 and be blown into the circulating vortex channel by the cooling fan 22. The air can flow along the circulating vortex channel and cool down various parts of the electromagnetic coil assembly 24, thereby improving the uniformity of heat dissipation for the electromagnetic coil assembly 24.

[0031] See Figures 3-4The base 2 includes a housing 21 and a mounting bracket 23 disposed within the housing 21. The housing 21 includes an upper housing 211 and a lower housing 212 connected vertically to each other. The upper housing 211 and the mounting bracket 23 enclose an annular air cavity, which forms the aforementioned circulating vortex. The lower housing 212 and the mounting bracket 23 enclose an installation cavity, in which a power supply module 26 is disposed. The power supply module 26 consists of a battery compartment 261 and a battery pack 262 placed within the battery compartment 261. The battery pack 262 is electrically connected to an electromagnetic coil 242 to supply power to it.

[0032] In this embodiment, a plurality of air inlets 2121 and a plurality of air outlets 2122 are provided on the side wall of the lower housing 212.

[0033] More specifically, it also includes a mounting frame 28 disposed on the mounting bracket 23 and located within the mounting cavity, with the cooling fan 22 disposed within the mounting frame 28. Specifically, the mounting frame 28 also has a cavity 281 with a top opening and a side opening. The top opening of the cavity 281 communicates with the circulation vortex channel, and the side opening of the cavity 281 communicates with a plurality of air inlets 2121 and a plurality of air outlets 2122. Specifically, the cavity 281 has a vertically arranged first partition 282 to divide the cavity 281 into a first cavity 2811 and a second cavity 2812. The cooling fan 22 is placed in the first cavity 2811, which is connected to the air inlet end of the circulation vortex channel and a plurality of air inlets 2121. The second cavity 2812 is connected to the air outlet end of the circulation vortex channel and a plurality of air outlets 2122.

[0034] Thus, under the action of the cooling fan 22, external air can enter the first cavity 2811 through several air inlets 2121, and then be blown towards the air inlet of the circulation vortex by the cooling fan 22. After the air flows along the circulation vortex, it is discharged from the air outlet of the circulation vortex into the second cavity 2812, and then discharged to the outside through several air outlets 2122.

[0035] In this embodiment, the mounting frame 28 and the mounting bracket 23 are integrally formed.

[0036] In addition, the top of the mounting bracket 23 is provided with a second partition 231, which separates the air inlet and outlet of the circulating vortex channel, thereby avoiding cross-interference of airflow between the air inlet and outlet areas, making the airflow more uniform and reducing losses. Furthermore, the top of the mounting bracket 23 is also provided with several support ribs 232 at intervals. When the electromagnetic coil assembly 24 is placed on the support ribs 232, the support ribs 232 can support the coil bracket 241, thereby limiting the position of the electromagnetic coil assembly 24.

[0037] SeeFigures 5-10 The mounting bracket 23 has a boss 233 at its top center, on which a temperature measuring component 25 is mounted. The temperature measuring component 25 partially extends out of the upper housing 211 to measure the temperature of the inner cup 12. Specifically, the temperature measuring component 25 includes a temperature measuring bracket 251 located within the boss 233, an NTC temperature probe 252 mounted on the temperature measuring bracket 251, and a sealing ring 253 located on the top of the boss 233. The sealing ring 253 abuts against the upper housing 211 and the boss 233 to form a waterproof seal. The upper housing 211 has a through hole 2112, through which the sealing ring 253 partially extends. The NTC temperature probe 252 passes through the sealing ring 253 and abuts against the bottom of the inner cup 12 to achieve temperature measurement.

[0038] Therefore, by setting the NTC temperature probe 252 on the temperature measuring bracket 251, when the user pulls the NTC temperature probe 252 upward, it can be prevented from falling out of the sealing ring 253 by the contact limit between the temperature measuring bracket 251 and the sealing ring 253.

[0039] Preferably, the boss 233 has a mounting groove 2331 with a top opening and a retaining groove 2332 with a top opening surrounding the mounting groove 2331. The temperature measuring bracket 251 is placed in the mounting groove 2331. The sealing ring 253 includes a sealing ring body 2531, which is a circular ring structure. The bottom of the sealing ring body 2531 is provided with a retaining rib 2532, which is engaged in the retaining groove 2332 to assemble the sealing ring 253 onto the boss 233. The upper and lower end faces of the sealing ring body 2531 abut against the upper housing 211 and the boss 233 respectively to achieve waterproof sealing. The middle part of the sealing ring body 2531 has a spherical arc-shaped part 2533 protruding upwards. The spherical arc-shaped part 2533 is partially disposed through the through hole 2112. The NTC temperature measuring probe 252 is disposed on the spherical arc-shaped part 2533.

[0040] Therefore, by forming a spherical arcuate surface 2533 on the sealing ring 253, the spherical arcuate surface 2533 has a certain elastic deformation force, and the NTC temperature probe 252 is inserted through the spherical arcuate surface 2533. When the cup body 1 is separated from the base 2, under the elastic force of the spherical arcuate surface 2533, it can drive the NTC temperature probe 252 to pass through the through hole 2112 of the upper shell 211. When the cup body 1 is placed on the base 2, the bottom of the cup liner 12 will abut against the NTC temperature probe 252 and drive it to overcome the elastic force of the spherical arcuate surface 2533 and move. At this time, the NTC temperature probe 252 is tightly attached to the bottom of the cup liner 12 to realize temperature detection, thereby ensuring the reliability and accuracy of temperature measurement.

[0041] In addition, by forming a spherical arc surface 2533 on the sealing ring 253, there is no need to set an additional spring to provide elastic force for the NTC temperature probe 252, thereby saving parts. At the same time, since the spring is usually made of metal, when the electromagnetic coil assembly 24 heats the cup 12, it will also heat the spring simultaneously, which will affect the temperature measurement of the NTC temperature probe 252 and reduce its temperature measurement accuracy.

[0042] See Figure 4 The installation cavity also includes a display module 27 located on one side of the power supply module 26. The display module 27 includes a keypad 271 and a display screen 272, both of which are electrically connected to the battery pack 262. The display screen 272 displays the water temperature signal obtained by the NTC temperature probe 252, allowing users to easily monitor the water temperature inside the inner cup 12 in real time. The keypad 271 has several control buttons, which users can press to adjust the water temperature inside the inner cup 12 in real time, making it very convenient.

[0043] Preferably, a power board is also provided inside the mounting cavity. The power board is electrically connected to the battery pack 262. The power board is provided with a power input interface that extends out of the lower housing 212, so as to charge the battery pack 262. This makes the electromagnetic heating water cup more applicable to a wider range of scenarios, and users can drink hot water anytime and anywhere, which is very convenient and practical.

[0044] See Figures 11-12 The cup body 1 also includes an outer shell 11 fitted around the outer periphery of the inner cup 12. The outer shell 11 can provide heat insulation to prevent the user from being burned when handling the cup body 1. The bottom of the outer shell 11 is recessed inward to form a cavity. A retaining ring 13 is installed in the cavity. The inner side wall of the retaining ring 13 is provided with several limiting grooves 131 at intervals. The upper shell 211 is also provided with several limiting buckles 2111 at intervals, which correspond one-to-one with the limiting grooves 131. Thus, when it is necessary to assemble the two, the upper shell 21 can be inserted into the bottom cavity of the outer shell 11, and the several limiting buckles 2111 can be inserted into the several limiting grooves 131 one by one. After rotating the cup body 1 at a certain angle, the limiting buckles 2111 can be locked and fixed in the limiting grooves 131 to achieve fixation. Similarly, when it is necessary to remove the cup body 1, simply rotate the cup body 1 in the opposite direction by a certain angle so that the limiting buckle 2111 disengages from the limiting groove 131, and then pull the cup body 1 upward to remove it from the base 2. The operation is convenient.

[0045] Therefore, when it is necessary to clean the cup body 1, the cup body 1 can be detached from the base 2. At this time, the cup body 1 does not have any electrical components, so it is more convenient and safer to clean.

[0046] Example 2 See Figures 14-15The difference between the electromagnetic heating water cup in this embodiment and that in embodiment one is that the mounting frame 28 in this embodiment is set on the battery compartment 261, and its structure is the same as that in embodiment one, so it will not be described in detail here.

[0047] The second cavity 2812 is further provided with a sealing sleeve 29, which abuts against the inner wall of the housing 21 to achieve a seal, thereby separating the air inlet and outlet. In addition, a number of air inlet holes 2121 are spaced around the bottom of the base 2 to achieve bottom air intake.

[0048] In summary, this utility model has the following technical effects: (i) The electromagnetic heating water cup of this utility model has a cooling fan 22 installed inside the base 2, which can dissipate heat from the electromagnetic coil 242 in a timely manner, prevent the electromagnetic coil 242 from getting too hot, thereby ensuring its insulation performance and extending its service life. At the same time, it can also avoid the high temperature environment generated by the electromagnetic coil 242 from affecting the temperature measuring component 25 inside the base 2, thereby ensuring the temperature measuring accuracy.

[0049] (ii) The electromagnetic heating water cup of this utility model, by opening a circulating vortex channel in the base 2 and setting the electromagnetic coil assembly 24 in the circulating vortex channel, when air enters the circulating vortex channel and flows along the circulating vortex channel, it can cool and dissipate heat at various positions of the electromagnetic coil assembly 24, thereby improving the heat dissipation uniformity of the electromagnetic coil assembly 24.

[0050] 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.
