Description

Technical Field

[0001] The utility model relates to the technical field of coaster warmers, in particular to a high-power coaster warmer with high safety. Background Art

[0002] When people drink water, the freshly boiled water is too hot and becomes cold again after a while. The storage time of warm boiled water suitable for drinking is too short, so people usually prepare a warming cup mat to place the water cup to heat the cup to prevent the water in the cup from being too cold and causing discomfort to the body.

[0003] A warming coaster can keep water at a suitable temperature. It heats the cup placed on it, keeping the water in the cup at a certain temperature, neither too hot nor too cold, so that users can drink hot water at any time. There are many types of warming coasters on the market, with different styles, which are affected by the user group and usage environment.

[0004] In actual applications, the coaster warmer is relatively small and its heating module has a relatively low power. Once turned on, the coaster warmer is in a continuous heating state, so that users can drink hot water at any time.

[0005] However, the existing cup warmers can only heat to 45-65 degrees due to their low power, so they can only play a role in keeping warm. Some users may need to heat the cup to a higher temperature. Utility Model Content

[0006] The existing warming cup pads can only achieve the heat preservation effect due to their low power, and cannot heat the water to a certain temperature according to the needs of customers.

[0007] To address the above problems, a high-safety, high-power cup warmer is proposed. By setting a PTC, water can be quickly heated to the required temperature according to user needs. By setting a thermal insulation component, the heat generated during the heating process is separated from the circuit board in the control component to avoid damage to it.

[0085] In an application scenario of this embodiment, the anti-scalding silicone pad 102 can be designed to be square and assembled on the upper shell 110 using double-sided tape or one-piece injection molding technology.

[0086] In a preferred embodiment, the control assembly 300 further includes a touch panel 340 ; the touch panel 340 is mounted on the outside of the front housing 140 for performing touch operations.

[0087] In a preferred embodiment, Figure 2 , Figure 2 This is a schematic diagram of the rear view structural layout of a high-safety, high-power cup warmer in the present invention; a plurality of groups of heat dissipation holes 131 are provided on the lower shell 130 for heat dissipation.

This thermally conductive layer (not shown) is made of thermally conductive silicone grease, and the heating plate 240 and the PTC 210 are fixed together by bolts, thereby improving heat conduction efficiency. By applying thermally conductive silicone grease to the PTC, the nut and the heating plate rivet are more tightly fixed, thereby maximizing the power of the heating element.
