Embodiment 1

[0061] Such as Figures 1 to 5 As shown, a kind of intelligent constant temperature pad comprises a circuit board assembly 1, a magnetic shield 2 covered on the component surface of the circuit board assembly 1, a magnetic isolation sheet 3 arranged on the back side of the circuit board assembly 1, and a magnetic isolation sheet 3 metal sheet 4 on the outer surface. The magnetic shielding cover 2 covers the components, and is sealed and bonded to the component surface of the circuit board assembly 1 by glue, the magnetic isolation sheet 3 is bonded to the back of the circuit board assembly 1 by adhesive, and the metal sheet 4 is bonded to the magnetic isolation sheet 3 by adhesive The outer surface is bonded, the copper skin layer of the circuit board 11 of the circuit board assembly 1 is provided with a receiving coil 12 for communicating with the transmitting coil 21 and receiving the energy sent by the transmitting coil 21, the magnetic shield 2 and the magnetic isolation s...

Embodiment 2

[0065] The difference from the above-mentioned embodiment 1 is that in order to further reduce the cost, the magnetic shield 2 and the magnetic isolation sheet 3 in the embodiment 1 are cancelled. After the cancellation, the heating and constant temperature functions of the constant temperature pad 10 are not reduced, and the metal sheet 4 slightly improved thermal conductivity. The rest of the content is exactly the same and will not be repeated here.

[0066] Such as Figure 6 , 7 As shown, an intelligent constant temperature container includes an intelligent constant temperature pad in the above-mentioned embodiment 1 or embodiment 2, and also includes a wireless charging transmitter seat 20 matched with the constant temperature pad, and a container 30 arranged on the wireless charging transmitter base 20 , the container 30 is filled with water 31, and the bottom of the container 30 is pasted with a constant temperature pad 10. The wireless charging transmitter base 20 i...

Abstract

An intelligent constant-temperature pad comprises a circuit board assembly, a magnetic shielding cover covering the element surface of the circuit board assembly, a magnetic isolation sheet arranged on the back surface of the circuit board assembly, and a metal sheet arranged on the outer surface of the magnetic isolation sheet. A copper sheet layer of a circuit board of the circuit board assemblyis provided with a receiving coil, a magnetic shielding cover and a magnetic isolation sheet, the receiving coil is used for communicating with the transmitting coil and receiving energy emitted by the transmitting coil, the magnetic shielding cover and the magnetic isolation sheet are used for shielding electromagnetic radiation, the magnetic isolation sheet has a heat conduction effect, and themetal sheet is used for generating vortexes and transferring heat. The receiving coil is a copper sheet wire, and the total thickness of the constant temperature pad is less than 3.5 mm. The intelligent constant-temperature pad starts to heat constant temperature after the transmitting end and the receiving end are in communication handshake, is small in size and ultrathin, can be directly attached to the bottom of a container, is very convenient to use, is low in cost, is safe and reliable, and has an intelligent constant-temperature function.

Description

technical field [0001] The invention relates to the technical field of wireless charging, in particular to an intelligent constant temperature pad, a constant temperature container, a constant temperature system and a constant temperature control method. Background technique [0002] There are basically three types of containers on the market that use wireless charging to heat constant temperature: [0003] The first is to use a light touch switch. When heating is required, press the light touch switch, and the wireless charging will start the transmission output power, and use the magnetic field eddy current to heat the metal sheet at the bottom of the container; [0004] The second is to directly detect through FOD (abbreviation of Foreign Object Detection, used to detect whether there is a metal object between the charger and the receiver) to determine whether it meets a certain size (referring to meet a certain power) of the metal sheet. heating; [0005] Both of the a...
