Therefore, the base of the wireless charger supporting the QI protocol can be used as a wireless charging base of portable equipment such as a mobile phone in the time of not heating the lunch box, and the universality of the product is greatly improved.

Of course, the wireless charging base 200 can work independently or synchronously; the significance is that one part can be used for heating work, and the other part can be used for mobile phone charging operation. The present invention may further include a power storage device 400, which may be integrated with the wireless charging base 200 (non-detachable), or may be a detachable and separate device.

The heating body 100 has mainly 7 portions, which are:

the thermal insulation box encloses a thermal insulation chamber 101, which may be a closed container made of aluminum, stainless steel or other thermally conductive material, and may be a rectangular parallelepiped, a cylinder or other type of configuration. The heating medium of the heat preservation cavity can be heated by water vapor or other heating modes.

The heating unit 102 is made of an electric heating material, and can be a resistance wire or other type heating material, the material is uniformly wrapped on the outer wall of the heat preservation box closed heat preservation cavity 101, and once the heating unit is electrified, electric energy can be converted into heat energy to uniformly heat the heat preservation box closed heat preservation cavity 101.

The temperature detection unit 103 mainly comprises a temperature detection sensor, which can be a thermocouple or other types of temperature sensors, and the temperature detection unit 103 can be uniformly distributed around the closed heat preservation cavity 101 of the heat preservation box or distributed at a specific point. The temperature of the whole heat preservation space can be detected in the heat preservation box closed heat preservation cavity 101 in the uniform distribution, the temperature uniformity can be detected, but the cost is high, and the detection unit is complex. The temperature sensor is distributed at a specific point, can detect the temperature of the point, and has the advantages of simple structure and lower cost, and the specific distribution mode is determined according to actual needs.

And the temperature setting and displaying unit 104 is used for displaying according to the result obtained by the temperature detecting unit 103, and meanwhile, a user can accurately set the temperature in the heat preservation box according to personal requirements.
