Detailed Description

The present invention will be further described with reference to the following specific embodiments, but the present invention is not limited to these specific embodiments. It will be recognized by those skilled in the art that the present invention encompasses all alternatives, modifications, and equivalents as may be included within the scope of the claims.

The first embodiment is as follows:

the heat insulation pad shown in fig. 1-3 comprises a base 50, an upper cover 20, a heating element 30 and a heat conduction panel 10; the base 50 and the upper cover 20 are covered to form a containing cavity 51; the heat conducting panel 10 is arranged on the upper cover 20, and the heat conducting panel 10 is provided with a convex part 11 matched with a vessel with a concave bottom; the heating element 30 is attached to the bottom surface of the heat conducting panel 10. In this embodiment, as shown in fig. 1, the heat conducting panel 10 is clamped on the upper cover 20 by a snap structure; other modes can also be adopted, such as bonding on the upper cover by adopting a bonding mode; or the upper cover is fixed in a pressing mode, and the conventional mode of fixing the heat-conducting panel on the upper cover can be realized. The heat conducting panel 10 has a boss 11 fitting the vessel with the bottom recessed; the heating element 30 is attached to the bottom surface of the heat conducting panel 10. As shown in fig. 3, when the dish 60 with a concave bottom needs to be heated, the upper surface of the protruding portion 11 is clamped on the concave bottom surface, so as to ensure that the upper surface of the protruding portion 11 is close to the bottom of the dish with a concave bottom, and because the heating element 30 is attached to the bottom surface of the heat conducting panel, the liquid in the dish with a concave bottom is rapidly heated.

The heat conductive panel 10 is made of aluminum. The aluminum has good thermal conductivity, and ensures the heat transfer efficiency. And because the density of aluminium is low, can reduce self weight by a wide margin, it is very light and laborsaving to take.

The top cover 20 and the base 50 are made of insulating plastic. Set up heat conduction panel 10 and upper cover 20 and base 50 into the structure of separation, upper cover 20 and base 50 adopt the insulating plastics material, guarantee the security of using, secondly, the heat conductivity of plastics is poor, prevents that the user from being scalded when touch the heat preservation pad carelessly, and has further guaranteed on heat conduction panel 10's the most conduction of heat is to the household utensils of treating the heating, prevents thermal loss.

The heating body 30 includes an insulating layer, and a heating wire (not shown in the drawings) enclosed in the insulating layer. The insulating layer is made of polyimide materials. The heating wire is encapsulated in the insulating layer, so that the use safety is ensured. The insulating layer is made of polyimide materials. The polyimide material is used as the insulating layer, and the polyimide has excellent insulating resistance and heat resistance, and can still resist heat and high temperature after long-term use. The insulation performance and the heat resistance of the insulation board are prevented from being reduced after long-term use, and the heating and heat preservation efficiency is prevented from being influenced.

In this embodiment, the thermal pad further includes a control board 40, the control board 40 is disposed in the accommodating cavity 51, one end of the control board 40 is connected to the heating element 30, and the other end is a USB connection port. The control panel 40 is connected with a power supply through a USB connection port, and only one USB wire is needed, so that the heating and heat preservation of the vessel can be realized, and the heating and heat preservation are quick and convenient.

As shown in fig. 2-3, the protruding portion 11 is cylindrical, so as to ensure the aesthetic property of the appearance, and on the other hand, the bottom of the existing canned-type vessel is generally a circular vessel 60 with a concave bottom, so that the protruding portion is cylindrical, and the protruding portion can better fit the outer surface of the existing canned-type vessel, thereby further ensuring the placing smoothness and increasing the heating area.

In this embodiment, the diameter of the circular cross-section of the boss 11 is less than 65 mm. As the canned beverages on the market have two specifications, one is canned beverage with the bottom diameter of 65mm, and the other is canned beverage with the bottom diameter of 54 mm; when heating heat-retaining canned vessel class beverage, if its bottom diameter is 65mm, as shown in fig. 3, the sunken household utensils of circular bottom 60, the diameter of its concave place face can slightly be lighter than 65mm, sets for the diameter of the circular cross section of bellying 11 to be less than 65mm to guarantee that the canned beverage that sells on the market for the bottom diameter is 65mm or is close this interval all can place on bellying 11 and heat-retaining.

Example two:

as shown in fig. 1-3, in the present embodiment, the protruding portion 11 is in the shape of a segment of a sphere, which is due to many canned beverages or canned products, the bottom of the segment of a sphere is not a concave flat bottom, but a concave segment of a sphere, so that in order to adapt to the heating of the bottom of such a vessel, the protruding portion 11 is in the shape of a segment of a sphere, so that it better fits the vessel 60 with a concave bottom, which is in the shape of a segment of a sphere, to achieve rapid heating. For the canned drink with the bottom diameter of 54mm, which is common in the market, the diameter of the surface where the concave part is formed is slightly smaller than 54mm, and the diameter of the circular cross section of the bulge part 11 is set to be smaller than 54mm, so that the canned drink with the bottom diameter of 54mm or close to the interval, which is sold in the market, can be placed on the bulge part 11 for heating and heat preservation.

It should be noted that, in order to adapt to the bottom shape of canned drinks appearing on the market, the shape and diameter of the cross section of the convex part can be correspondingly set, and the invention contents included in the present invention belong to the invention contents.

The above embodiments can be freely combined as needed. The foregoing has been a detailed description of the preferred embodiments and principles of the present invention, and it will be apparent to those skilled in the art that variations may be made in the specific embodiments based on the concepts of the present invention, and such variations are considered as within the scope of the present invention.
