The terms "first", "second", etc. in the description and claims of the present utility model or the above drawings are used to distinguish different objects and not to describe a specific order.

[0024] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present utility model. The phrase does not necessarily refer to the same embodiment when it appears in various places in the specification, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art 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 the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings.

[0026] As Figures 1 - 3As shown in the figure, an anti-scalding heating base includes a housing 1, a placement panel 2 made of high-temperature resistant material, an electromagnetic coil 4, a panel temperature sensor 21, a main board 5, a button temperature sensor 61, and an alarm 7. The placement panel 2, the electromagnetic coil 4, and the panel temperature sensor 21 are all arranged on the top of the housing 1, and both the electromagnetic coil 4 and the panel temperature sensor 21 are located below the placement panel 2. There is a cavity a inside the housing 1, and both the main board 5 and the button temperature sensor 61 are arranged in the cavity a. There is a control button 6 on one side of the housing 1, and the button temperature sensor 61 is adjacent to the control button 6. The alarm 7 is arranged on the housing 1. The alarm 7, the electromagnetic coil 4, the panel temperature sensor 21, and the button temperature sensor 61 are all electrically connected to the main board 5. The alarm 7 is used to remind the user that the temperatures of the placement panel 2 and the control button 6 are too high. When in use, the main board 5 will supply power to the panel temperature sensor 21 and the button temperature sensor 61. The panel temperature sensor 21 will detect the temperature of the placement panel 2 in real time, while the button temperature sensor 61 will detect the temperature of the control button 6 in real time. When the temperatures of the placement panel 2 and the control button 6 are relatively high (such as higher than 45 degrees, this temperature can be preset by the main board 5), the main board 5 will control the alarm 7 to send a reminder signal. When the temperatures of the placement panel 2 and the control button 6 drop to the normal range, the alarm 7 will stop sending the reminder signal, so that the user can understand the temperature levels of the placement panel 2 and the control button 6, and operate according to their temperature conditions, avoiding being scalded by touching them without protection and improving the user experience.

[0027] Specifically, the user can place the water cup or mobile device to be heated on the placement panel 2. Subsequently, the main board 5 externally connects a power supply to supply power to the electromagnetic coil 4. The main board 5 will identify the placed object through the electromagnetic coil 4. When the placed object is a water cup, the electromagnetic coil 4 will heat the metal sheet at the bottom of the water cup, thereby heating the water in the water cup through the metal sheet. When the placed object is a mobile device, the electromagnetic coil 4 will perform wireless charging on the mobile phone, so that the heating base combines the functions of heating and wireless charging, improving the practicality of the heating base. The main board 5 can be obtained through the market channels and will not be elaborated in this embodiment.

[0028] In one embodiment, the alarm 7 is a speaker, which gives a high-temperature reminder by emitting a prompt sound.

[0029] Furthermore, there is a receiving groove b on the top of the housing 1. The placement panel 2 is embedded in the upper end of the side wall of the receiving groove b and covers the opening of the receiving groove b. Both the electromagnetic coil 4 and the panel temperature sensor 21 are arranged on the bottom wall of the receiving groove b. The panel temperature sensor 21 is arranged at intervals below the placement panel 2, which can reduce the influence of the high temperature of the placement panel 2 on the panel temperature sensor 21 and extend the service life of the panel temperature sensor 21.

[0030] Further, the button temperature sensor 61 is integrated on the main board 5, and the lead of the button temperature sensor 61 is bent so that its sensing end is adjacent to the control button 6, in order to reduce the wiring inside the housing 1 and lower the production difficulty and cost of the anti-scalding heating base.

[0031] Further, the alarm 7 is a lamp bead, which is embedded on the side wall of the housing 1 and adjacent to the control button 6. When the temperatures of the placement panel 2 and the control button 6 are relatively high, the main board 5 will control the lamp bead to emit red light, while when the temperatures of the placement panel 2 and the control button 6 are within the normal range, the main board 5 will control the lamp bead to emit blue light, so that the user can judge the temperatures of the placement panel 2 and the control button 6 according to the color of the lamp bead.

[0032] Further, there are two lamp beads, which are symmetrically distributed along the horizontal direction on both sides of the control button 6 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, both the housing 1 and the pressing end of the control button 6 are made of metal. An air inlet hole 11 is opened on the side wall of the cavity a, and an air outlet hole 12 is opened on the bottom wall of the cavity a. A fan 8 is provided at the bottom of the cavity a. The air outlet end of the fan 8 is aligned with the air outlet hole 12, and the fan 8 is electrically connected to the main board 5. During use, the main board 5 will control the fan 8 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 air inlet hole 11. The air will flow through the main board 5 and the inner wall of the cavity a and take away the heat of the main board 5 and the housing 1, and finally be discharged to the outside through the fan 8 and the exhaust hole in sequence, thereby using the housing 1 to adsorb the heat of the placement panel 2 and the pressing end of the control button 6 to help the two cool down quickly and prevent scalding the user.

[0034] Further, there are two air inlet holes 11, which are symmetrically arranged on both sides of the housing 1 to increase the air flow rate in the cavity a by means of air inlet from both sides and improve the cooling efficiency of the placement panel 2, the housing 1, the control button 6 and the main board 5.

[0035] Further, a partition net 9 is laid at the air inlet hole 11. The partition net 9 can prevent sundries from entering the cavity a through the air inlet hole 11 and avoid the sundries from damaging the components in the cavity a.

[0036] Further, a power interface 13 is provided on one side of the housing 1. The power interface 13 is electrically connected to the main board 5, so that the user can connect a wire to the main board 5 for power supply through the power interface 13.

[0037] Further, a plurality of cushion blocks 3 are evenly distributed at the bottom of the housing 1 to support the housing 1 through the plurality of cushion blocks 3, 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 12.

[0038] Obviously, the embodiments described above are only a part of the embodiments of the present utility model, rather than all of them. The preferred embodiments of the present utility model are shown in the accompanying drawings, but they do not limit the patent scope of the present utility model.
