Embodiment 1

[0050] This implementation relates to a wireless power supply heating device, including a control module, a storage module connected to the control module, a working part with a coil inside for carrying placed objects, a frequency scanning and power adjustment module, a frequency response signal acquisition module, and a wireless launch module.

[0051] When an object is placed on the working part, the coil placed in the working part sends a signal to the wireless transmitting module. Wherein the wireless transmitting module and the working part with the coil constitute an existing wireless charging device, such as a wireless charging device for a mobile phone; and the communication between the existing wireless charging device and a device requiring wireless charging such as a mobile phone The identification has been maturely used, and will not be repeated here; after the wireless transmission module recognizes the placed object, wireless charging is performed on the placed o...

Embodiment 2

[0062] The wireless power supply heating method is as Figure 5 shown, including the following steps:

[0063] Step a, placing the placed object in the working area of ​​the working part of the wireless power supply heating device;

[0064] Step b, the frequency scanning and power adjustment module inputs current into the coil under the control of the control module, and the changing frequency of the current increases linearly and monotonously, so that the coil generates a magnetic field with changing frequency;

[0065] Step c, under the control of the control module, the frequency response signal acquisition module detects the parameter that the eddy current loss power of the placed object on the working part varies with the frequency of the magnetic field, and transmits the detected data to the said control module;

[0066] Step d, the control module compares the detected data with the parameter threshold stored in the storage module to identify the placed object; and aft...

Embodiment 3

[0068] This embodiment relates to a placed object, such as Figure 6 As shown, the placed object includes a container body. This embodiment is an existing ceramic water cup 11, and a composite metal material 12 arranged at the bottom of the ceramic water cup 11. The composite metal material 12 is made of a specific ratio of metal or metal oxide and It is made by mixing high-frequency soft magnetic materials, in parts by mass: 2-7 parts of antioxidant, 1-6 parts of solvent, 75-95 parts of silver powder, and 1-22 parts of high-frequency soft magnetic material; The formula is as follows: 11-13 parts of zirconium, 87-89 parts of platinum; the solvent is divided by mass, and the formula is as follows: 77 parts of boron silicate, 13 parts of lithium carbonate, 5 parts of bismuth oxide, 0.5 part of strontium carbonate, zinc oxide 0.5 parts, 4 parts of niobium oxide; the silver powder is at least one of silver carbonate, silver oxide, and metal elemental silver, calculated according t...

Abstract

Disclosed is a wireless power supply heating device, a heating method, a placing material and a preparation method thereof. The wireless power supply heating device is used for recognizing the placingmaterial placed in the working area and heating the recognized placing material. The wireless power supply heating device comprises a control module, a storage module connected to the control moduleand used for storing threshold value of worm current loss power which changes with the field frequency of the pacing material needs to be recognized, a coil used for generating a magnet field, a frequency scanning and power adjusting module used for inputting current to the coil, and a frequency response signal collecting module used for detecting parameters of the worm current loss power which changes with the field frequency of the pacing material. The control module controls the frequency scanning and power adjusting module to generate a magnetic field with stable frequency and heats the recognized placing material; in the condition of not adding any circuit at a heating end, effective recognition, safety and reliability of the placing material is achieved.

Description

technical field [0001] The invention relates to the field of wireless charging, in particular to a wireless power supply heating device, the invention also relates to a wireless power supply method, and the invention also relates to a placed object and a preparation method thereof. Background technique [0002] As a new energy transmission method, wireless charging has been gradually accepted by the consumer electronics market, and is increasingly integrated into electronic products such as mobile phones. [0003] Wireless charging uses the principle of electromagnetic induction to convert the electric energy in the closed circuit into magnetic energy in the open space at the transmitting end, and then converts the magnetic energy into electric energy at the receiving end, thereby realizing wireless transmission of energy. Due to the existence of the eddy current effect, when the metal material is placed in a changing magnetic field, it will absorb the energy of the magnetic...
