Abstract

An output control device includes an output component, a first switch and a second switch. The output component includes a first output coil used for controlling, when the first circuit is turned on and the second circuit is not turned on, the first output coil to enter a heating working state, and controlling, when the first circuit is not turned on and the second circuit is turned on, the first output coil to enter a power transmission working state. The first switch is located in the first circuit and used for turning on the first circuit when being closed. The second switch is located in the second circuit and used for turning on the second circuit when being closed.

First claim

The invention claimed is:

a second circuit;
an inductor arranged in the second circuit;
a first switch, and
a second switch, wherein:
the output component comprises a first output wire coil, and the output control device is configured to control the first output wire coil to enter a heating working state when the first circuit is turned on and the second circuit is not turned on and to control the first output wire coil to enter a power transmission working state when the first circuit is not turned on and the second circuit is turned on;
the first switch is located in the first circuit and is configured to turn on the first circuit when being closed; and
the second switch is located in the second circuit and is configured to turn on the second circuit when being closed.

2. The device according to claim 1 , wherein the first switch comprises a first sub-switch and a second sub-switch, wherein:
the first sub-switch is located in a first sub-circuit and is configured to turn on the first sub-circuit when being closed; and
the second sub-switch is located in a second sub-circuit and is configured to turn on the second sub-circuit when being closed,
wherein the first sub-circuit and/or the second sub-circuit constitute the first circuit.

3. The device according to claim 2 , wherein the output component is configured to:
when the first sub-circuit is turned on and the second sub-circuit is not turned on, the first output wire coil is controlled to enter a first heating working state in which a first output power interval is adopted for heating.

4. The device according to claim 3 , wherein the device is configured to switch from the first heating working state into a second heating working state in which a second output power interval is adopted for heating when the second sub-circuit is turned on and the first sub-circuit is not turned on, and wherein the first heating working state is different from the second heating working state.

5. The device according to claim 1 , further comprising:
a processor, configured to determine that the first output wire coil of the output component enters the heating working state or the power transmission working state based on a control instruction.

6. The device according to claim 5 , wherein:
the processor is configured to control the first switch to be closed and the second switch not to be closed when it is determined that the first output wire coil of the output component enters the heating working state; and
the processor is configured to control the second switch to be closed and the first switch not to be closed when it is determined that the first output wire coil of the output component enters the power transmission working state.

7. The device according to claim 1 , further comprising a first capacitor connected in series to the inductor.

8. The device according to claim 7 , wherein the first switch is configured so that a current bypasses the inductor and the first capacitor when the first switch is closed.

9. An output control method, comprising:
controlling a first output wire coil of an output component to enter a heating working state when a first circuit is turned on and a second circuit is not turned on, wherein an inductor and a capacitance are arranged in the second circuit; and
controlling the first output wire coil of the output component to enter a power transmission working state when the first circuit is not turned on and the second circuit is turned on;
wherein the first circuit is provided with a first switch and is turned on when the first switch is closed, and while the first switch is closed, a current bypasses the inductor and a capacitor in the second circuit, and the second circuit is provided with a second switch and is turned on when the second switch is closed.

10. The method according to claim 9 , wherein controlling a first output wire coil of an output component to enter a heating working state when a first circuit is turned on and a second circuit is not turned on comprises the following operations:
when a first sub-circuit is turned on and a second sub-circuit is not turned on, the first output wire coil enters a first heating working state in which a first output power interval is adopted for heating;
when a second sub-circuit is turned on and a first sub-circuit is not turned on, the first output wire coil enters a second heating working state in which a second output power interval is adopted for heating; and
when a first sub-circuit is turned on and a second sub-circuit is turned on, the first output wire coil enters a third heating working state in which a third output power interval is adopted for heating;
wherein,
the first sub-circuit is provided with a first sub-switch and is turned on when the first sub-switch is closed; and
the second sub-circuit is provided with a second sub-switch and is turned on when the second sub-switch is closed.

11. The method according to claim 9 , further comprising:
determining that the first output wire coil of the output component enters the heating working state or the power transmission working state based on a control instruction.

12. A non-transitory computer-readable storage medium, wherein the non-transitory computer-readable storage medium stores one or more programs executable by one or more processors to implement the steps of the output control method according to claim 9 .
