The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0025] In order to enable those skilled in the art of this technology to better understand the solution of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0026] Such as Figures 1-3As shown in the figure, a heating base includes a housing 1 made of metal, a panel 2 made of high-temperature resistant material, an electromagnetic coil 3, a fan 4, a sensor 5, an alarm 6 and a main board 7. A receiving groove b is provided at the top of the housing 1, and the electromagnetic coil 3 is laid on the bottom wall of the receiving groove b. The panel 2 is embedded at the upper end of the side wall of the receiving groove b. A cavity a is provided inside the housing 1. Air inlet holes 13 communicating with the cavity a are symmetrically opened on both sides of the housing 1. An air outlet hole 14 is opened on the bottom wall of the cavity a. The fan 4 is arranged on the bottom wall of the cavity a, and its air outlet end is aligned with the air outlet hole 14. The sensor 5 is arranged on the bottom wall of the receiving groove b for detecting the temperature of the panel 2. The alarm 6 is arranged on the outer wall of the housing 1 for reminding the user that the temperature of the panel 2 is too high. The main board 7 is arranged inside the cavity a and is electrically connected to the electromagnetic coil 3, the fan 4, the sensor 5 and the alarm 6 respectively. When the user removes the heated water cup, the sensor 5 will continuously feedback the temperature information of the panel 2 to the main board 7. If the temperature of the panel 2 rises to the preset temperature of the main board 7 (the preset temperature can be determined according to actual requirements), the main board 7 will control the alarm 6 to give a warning, reminding the user that the temperature of the panel 2 is relatively high at this time. At the same time, the main board 7 will control the fan 4 to rotate, so that a negative pressure is formed in the cavity a, driving the outside air to flow into the cavity a through the two air inlet holes 13. After the air enters the cavity a, it will flow along the side wall of the cavity a to the bottom wall, and finally be discharged through the fan 4 and the air outlet hole 14 in sequence. The air flowing through the cavity a will take away the heat of the housing 1, and the housing 1 made of metal will adsorb the heat of the panel 2 through the connection part, achieving the purpose of helping the panel 2 to cool down quickly. After the temperature of the panel 2 drops to a reasonable range, the main board 7 will cancel the alarm of the alarm 6, so that the user can distinguish the temperature of the panel 2 through the alarm 6, preventing the panel 2 from being hot to the touch or affecting other devices placed on the panel 2 (such as wirelessly charging mobile devices such as mobile phones using the electromagnetic coil 3).

[0027] Further, the housing 1 is composed of an upper shell 11 and a lower cover 12. The upper shell 11 opens downward, and the lower cover 12 covers the bottom opening of the upper shell 11 and encloses the cavity a with the inner wall of the upper shell 11. The air inlet holes 13 are opened on both sides of the upper shell 11, and the air outlet hole 14 is opened on the lower cover 12, so as to remove the lower cover 12 to expose the cavity a, facilitating the assembly of the heating base.

[0028] Further, a through hole 15 communicating with the cavity a is opened on the bottom wall of the receiving groove b. The through hole 15 can allow the electromagnetic coil 3 to pass through vertically. During assembly, the electromagnetic coil 3 arranged on the magnetic isolation sheet can be first connected to the main board 7, and then the three of them are placed into the cavity a together. Then, the magnetic isolation sheet and the electromagnetic coil 3 are vertically passed through the through hole 15 and placed on the bottom wall of the receiving groove b, so as to reduce the connection difficulty between the electromagnetic coil 3 and the main board 7 when assembling the heating base. At the same time, the air flowing into the cavity a from the air inlet hole 13 can also be exchanged with the air in the receiving groove b through the through hole 15, so as to improve the cooling efficiency of the panel 2.

[0029] Further, the air inlet hole 13 is an oval hole and is arranged along the circumferential direction of the housing 1. The opening of the slender structure can increase the flow rate of the air passing through the air inlet hole 13, so that this part of the air can quickly take away the heat from the inner wall of the housing 1, and further improve the heat dissipation efficiency of the housing 1 and the panel 2.

[0030] Further, a control button 8 is provided on one side of the housing 1. The control button 8 is electrically connected to the main board 7. The user can operate the main board 7 through the control button 8 and use the main board 7 to control the operation of the electromagnetic coil 3 and the fan 4.

[0031] Further, the alarm 6 is a lamp bead. The lamp bead is embedded on the side wall of the housing 1. When the temperature of the panel 2 is relatively high, the main board 7 will control the lamp bead to emit red light. When the temperature of the panel 2 is within the normal range, the main board 7 will control the lamp bead to emit blue light, so that the user can judge the temperature of the panel 2 according to the color of the lamp bead and avoid being scalded.

[0032] Further, there are two lamp beads, which are symmetrically distributed on both sides of the control button 8 along the horizontal direction to expand the prompting range of the lamp beads and ensure that the user can intuitively perceive the color change of the lamp beads.

[0033] Further, a separation net 9 is laid at the air inlet hole 13. The separation net 9 can prevent sundries from entering the cavity a through the air inlet hole 13 and avoid the sundries from damaging the components in the cavity a.

[0034] Further, a power interface 16 is provided on one side of the housing 1. The power interface 16 is electrically connected to the main board 7, so that the user can connect a wire to the power interface 16 to supply power to the main board 7.

[0035] Further, a plurality of cushion blocks 17 are evenly distributed at the bottom of the housing 1 to support the housing 1 through the plurality of cushion blocks 17, so that the bottom wall of the housing 1 is spaced from the placement plane, so that the air after adsorbing heat can be discharged through the air outlet hole 14.

[0036] Obviously, the embodiments described above are only a part of the embodiments of the present invention, rather than all the embodiments. The preferred embodiments of the present invention are given in the drawings, but do not limit the patent scope of the present invention. The present invention can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosed content of the present invention more thorough and comprehensive.
