The control module 50 also starts the fan module 60 based on the start signal, so that the external air enters the heating device 1a, passes through the heating module 20, and finally flows out of the heating device 1a, thereby generating a hot air flow for drying objects. For example, when the electronic device is a hair dryer, the heating device 1a generates a hot air flow to dry hair and the like.
Optionally, as shown in fig. 1, in the first embodiment, the heating device 1a further includes a key module 70 electrically connected to the control module 50, where the key module 70 is configured to respond to different operations of a user to generate different activation signals and send the different activation signals to the control module 50.

The control module 50 is further configured to control the first power supply module 30 and/or the second power supply module 40 to supply power to the heat generating module 20 when receiving different on signals, so that the heat generating module 20 generates heat.
The key module 70 may be any operation unit capable of generating different opening signals in response to different operations of a user, for example, may include one or more physical keys, or may include a touch panel with one or more virtual keys, which is not limited thereto.

The second power supply module 40 supplies power to the second heating element 22 under the control of the control module 50, so that the second heating element 22 heats. That is, the first heating element 21 and the second heating element 22 are independent from each other, and the control module 50 may control only one of the two heating elements to generate heat, or may control both heating elements to generate heat simultaneously.
The first heating element 21 and the second heating element 22 may be heating wires or mica sheets, and are not limited thereto as long as they can generate heat by passing through them.
As described above, the key module 70 may generate different activation signals in response to different operations of the user.

In addition, when the user wants to dry the hair or the object slowly, the user can generate a second opening signal through a second operation, wherein the target output power corresponding to the second opening signal is smaller than the target output power corresponding to the first opening signal. The control module 50 is configured to control the first power supply module 30 to supply power to the first heating element 21 when the second start signal is received and the first power supply module 30 is externally connected to the mains, so that the first heating element 21 generates heat. It can be appreciated that, in the case where the first power supply module 30 is externally connected to the mains supply, the first power supply module 30 is preferably used to supply power to the first heating element 21 so that the first heating element 21 generates heat, so that the energy storage of the second power supply module 40 is not required to be consumed, and the energy storage of the second power supply module 40 is advantageously saved for future use. Optionally, when the first power supply module 30 is not externally connected to the mains supply or no mains supply is available in the current environment, the control module 50 is further configured to control the second power supply module 40 to supply power to the second heating element 22 when the second start signal is received and the first power supply module 30 is not externally connected to the mains supply, so that the second heating element 22 heats. Therefore, the heating device 1a can be normally used in a scene without commercial power, and the application scene of the heating device 1a is enlarged.
Referring to fig. 3, in another embodiment, the heat generating module 20 includes only a third heat generating element 23, and the third heat generating element 23 is electrically connected to both the first power supplying module 30 and the second power supplying module 40. The third heating element 23 may include a heating wire, a mica sheet, or other elements that can generate heat when energized.
When the user wants to blow-dry hair or objects using the heating device 1a, the user may generate a third opening signal through a third operation.

It will be appreciated that the first power supply module 30 and the second power supply module 40 supply power to the third heating element 23 simultaneously, so that the heat energy generated by the third heating element 23 can be increased, thereby facilitating quick drying of hair or objects. In addition, the control module 50 is further configured to control the second power supply module 40 to supply power to the third heating element 23 when the third on signal is received and the first power supply module 30 is not externally connected to the mains supply, so that the third heating element 23 generates heat, and therefore, even if the user is not powered by the mains supply in the environment, the heating device 1a can be used, and the application scenario of the heating device 1a can be expanded.
It should be noted that the heating device 1a provided by the present application further includes a housing, where the heating module 20, the first power supply module 30, the second power supply module 40, the control module 50, and the fan module 60 mentioned above may be disposed in the housing, and the key module 70 may be disposed on the housing.
It will be appreciated that when the second power module 40 supplies power to the heat generating module 20, the current output of the second power module 40 may cause the second power module 40 to generate heat itself. Alternatively, in the first embodiment, the second power supply module 40 and the heat generating module 20 are sequentially arranged at intervals along the air outlet direction of the heating device 1a. Optionally, the second power supply module 40 is disposed between the heat generating module 20 and the fan module 60, so that the air blown by the fan module 60 can be used to dissipate heat of the second power supply module 40, and meanwhile, after the air blows through the second power supply module 40, part of heat of the second power supply module 40 is taken away, so that the air temperature is increased, and the temperature of the air entering the heat generating module 20 is increased. That is, the second power supply module 40 is placed in the air duct of the heating apparatus 1a, and the heat emitted from the second power supply module 40 is utilized.

The control module 50 and the protection module 80 are simultaneously used for preventing the second power supply module 40 from overdischarging, so that the double protection function is provided, the second power supply module 40 can be continuously protected by one of the control module 50 and the protection module 80 when the detection module of the other module fails, and the safety guarantee is higher.
