Description

Technical Field

[0001] The utility model relates to the technical field of wireless heating thermos cups, in particular to an insulated constant temperature cup and a constant temperature cup system. Background Art

[0002] A constant temperature cup is usually equipped with a constant temperature cup mat. By placing the powered-on constant temperature cup mat on the constant temperature cup, the liquid in the constant temperature cup can be kept warm.

[0003] The existing ways of supplying power to the constant temperature cup by the constant temperature cup mat include a wired connection and a wireless power supply mode. As mentioned in a Chinese patent application with the publication number CN110933794 for an intelligent constant temperature electricity, constant temperature container and constant temperature control method, a transmitting coil is provided inside the constant temperature cup mat, and a metal sheet is provided at the bottom of the cup body. When the transmitting coil is energized to generate a magnetic field, and when the cup body drives the metal sheet close to the magnetic field generated by the transmitting coil, eddy currents are generated on the metal sheet, thereby heating the liquid in the cup body.

[0004] However, when the cup body is made of a conductive material, when the cup body approaches the transmitting coil, the magnetic field generated by the transmitting coil will simultaneously cause eddy currents to be generated at the bottom of the cup body, thereby rapidly increasing the temperature of the cup body, easily burning out the outer shell of the constant temperature cup mat and scalding the human body. Therefore, a self-protection function is usually set in the circuit inside the constant temperature cup mat, that is, when a cup body made of a conductive material approaches the constant temperature cup mat, the constant temperature cup mat will be in a self-protection state, and the power supply will stop supplying power to the transmitting coil.

[0005] Moreover, the heating efficiency of the method of heating the metal sheet by eddy currents is relatively low, and the heat preservation effect is poor. Summary of the Utility Model

[0006] The purpose of the utility model is to provide an insulated constant temperature cup and a constant temperature cup system, which are not easy to trigger the self-protection function of the constant temperature cup mat, and use a temperature-adjusting sheet heated by electricity to heat the cup body, and have a good heat preservation effect.

[0044] Second aspect, a constant temperature cup system includes a constant temperature cup mat and the above-mentioned insulated constant temperature cup, and an emission coil is provided in the constant temperature cup mat. The constant temperature cup mat is a prior art with a self-protection function as described in the Chinese patent application with the publication number CN112583141B.

[0045] The working principle of this embodiment is described as follows: First, power on the constant temperature cup mat. After the emission coil in the constant temperature cup mat is powered on, it generates a magnetic field. Then, place the insulating cup body 1 on the constant temperature cup mat. After the receiving coil 4 in the installation cavity 3 enters the magnetic field generated by the emission coil, through electromagnetic induction, the receiving coil 4 generates alternating current. The receiving coil 4 transmits the alternating current to the circuit board 5. After converting the alternating current into direct current through the rectification circuit provided in the circuit board 5, the circuit board 5 transmits the direct current to the temperature regulating piece 6. Heating the temperature regulating piece 6 by electrifying has a higher heating efficiency than heating the metal piece by eddy current in the prior art, so that the heat preservation effect of the constant temperature cup system is better.

[0046] The constant temperature cup system includes a wireless charging module provided in the constant temperature cup mat and a wireless power supply circuit provided in the constant temperature cup. The wireless power supply circuit includes a main control module, a temperature control module, and a heating module. The main control module is used to convert the energy received by the receiving coil 46 into current and voltage and supply power to the temperature control module and the heating module. The temperature control module is used to detect the temperature at the bottom of the container in real time and control the working state of the heating module according to the detected temperature.

[0047] The wireless charging module includes a transmitting MCU, a frequency oscillator, an emission coil, and a frequency oscillator, which are respectively electrically connected to the transmitting MCU, and the frequency oscillator is electrically connected to the emission coil.

[0048] The temperature control module includes a temperature control MCU, a temperature sensor 1113, and a power control electronic switch, which are respectively electrically connected to the temperature control MCU. The temperature sensor 1113 is used to detect the temperature at the bottom of the container in real time. The temperature control MCU is electrically connected to the main control module, and the output end of the power control electronic switch is connected to the heating module.

[0049] The main control module includes a main control MUC, a full-bridge synchronous rectification module and a modulation and demodulation module, which are respectively connected to the main control MCU, an overvoltage protection circuit electrically connected to the full-bridge rectification module, a voltage stabilization module electrically connected to the overvoltage protection circuit, and a receiving coil 6, which is respectively electrically connected to the full-bridge rectification module and the modulation and demodulation module. The main control MCU communicates with the wireless charging module through the modulation and demodulation module and the receiving coil 6. The voltage stabilization module uses an LDO voltage regulator. The modulation and demodulation module includes an ASK modulation circuit and an FSK demodulation circuit to realize two-way wireless charging communication between the main control module and the wireless charging module.

[0050] The full-bridge synchronous rectification module includes a logic detection circuit, a rectification circuit, and a drive circuit. The logic detection circuit is electrically connected to the main control MCU. The drive circuit is electrically connected to the logic detection circuit and the rectification circuit respectively. The rectification circuit is connected to the receiving coil 6. The rectification circuit includes 4 N-MOSFETs, and the 4 N-MOSFETs are connected into a rectifier bridge structure for rectifying the energy received by the receiving coil 6 and outputting it to provide a startup voltage for the main control MCU. The full-bridge synchronous rectification module in this embodiment uses a common rectifier bridge, which will not be elaborated in this article.

[0051] Initially, the alternating current input by the receiving coil 4 will flow through the parasitic diode of the MOSFET, and the parasitic diode rectifies and outputs to provide a startup voltage for the chip. After the chip is powered on, the system switches the working mode of the rectifier bridge according to the load current. When the load is light, the rectifier bridge works in the asynchronous mode (parasitic diode mode), and when the load is heavy, it works in the synchronous mode (MOSFET switching mode) to ensure high efficiency and high stability of wireless charging; the wireless charging ASK modulation circuit and FSK demodulation circuit realize two-way wireless charging communication; the rectified voltage overvoltage protection circuit will trigger the VRECT voltage clamping function to limit the VRECT voltage when the rectified voltage VRECT exceeds 15V (the gear can be configured by software).

[0052] Due to the free-position characteristic of wireless charging, the rectified voltage VRECT is not a stable voltage, and there will be a large fluctuation in the rectified voltage VRECT during the process of moving the charging device. The main control chip integrates a voltage-stabilizing LDO. After the rectified voltage VRECT passes through the internal voltage-stabilizing LDO, it provides a stable DC voltage for the subsequent load. The output voltage and current of the voltage-stabilizing LDO can be set by software. The voltage setting range is 3.6V to 9V, with a step of 50mV; the output current limiting setting range is 0 to 1600mA, with a step of 50mA. The voltage-stabilizing LDO has safety protection functions such as input undervoltage protection, input dynamic regulation (Dynamic Power Management, DPM), output overcurrent protection, and output current limiting. When the charging device moves or is displaced, the rectified voltage VRECT will drop. When it drops below the DPM threshold of the LDO, the voltage-stabilizing LDO will automatically reduce the output current to maintain the continuity of wireless charging and improve the anti-displacement ability of wireless charging.

[0053] When the main control outputs stable voltage and current to the temperature control MCU, the MCU displays the temperature according to the parameters fed back by the temperature sensor 11; when the temperature reaches the set temperature, the temperature MCU outputs information to turn on the power switch, and at this time the heating device works. When the temperature sensor 11 reaches the set value, the temperature MCU stops outputting information to turn off the power switch, and the heating device stops working.
