All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.

The following detailed description of the embodiments of the present disclosure is provided in conjunction with the accompanying drawings.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a control circuit of an atomizer according to a first embodiment of the present application.

The control circuit 100 of the atomizer of the present embodiment includes a switch module 11 and a microphone 12, the switch module 11 includes a first connection end 111, a second connection end 112 and a control end 113, the first connection end 111 is connected to the power module 200 of the atomizer, the second connection end 112 is connected to the heating element 300 of the atomizer, and the control end 113 is connected to the microphone 12.

For the switch module 11, when the control terminal 113 inputs the first level, the first connection terminal 111 is conducted with the second connection terminal 112, that is, the power module 200 is conducted with the heating element 300, and the power module 200 directly supplies power to the heating element 300, so as to ensure the power supply. When the control terminal 113 inputs the second level, the first connection terminal 111 is disconnected from the second connection terminal 112, and the power module 200 is disconnected from the heat generating element 300, i.e. the power supply and the heat generation are stopped. The first level and the second level in this embodiment are a high level and a low level, respectively.

The microphone 12 is used for sensing an external trigger and generating different level signals, for example when applied in a nebulizer, sensing the force of the suction and then generating different level signals, which may be PMW signals, including different levels, for respectively controlling the power supply of the heating element.

This embodiment utilizes the signal of switch module response miaow head, switches on and off control power module and heating element, directly utilizes power module to supply power to heating element, has avoided miaow head itself to output's restriction, has improved output relatively speaking, has strengthened the load capacity of atomizer.

The switch module 11 may employ electronic components capable of realizing the above-described functions. Referring to fig. 2 and 3, fig. 2 is a schematic structural diagram of a second embodiment of a control circuit of an atomizer according to the present application, and fig. 3 is a schematic structural diagram of a third embodiment of a control circuit of an atomizer according to the present application.

In fig. 2, the switch module 11 includes a first MOS transistor Q1, which is an NMOS transistor in this embodiment.

The gate G of the first MOS transistor Q1 is used as the control terminal 113, the source S of the first MOS transistor Q1 is used as the first connection terminal 111, and the drain D of the first MOS transistor Q1 is used as the second connection terminal 112.

Specifically, the positive electrode of the power module 200 is connected to one end of the heating element 300, the negative electrode of the power module 200 is connected to the source S of the first MOS transistor Q1, and the other end of the heating element is connected to the drain D of the first MOS transistor Q1.

When the microphone 12 outputs a high level, i.e., a first level, to the gate G of Q1, Q1 is turned on, i.e., the power module 200 is turned on with the heating element 300, and the power module 200 supplies power to the heating element 300, so that the heating element 300 generates joule heat. At this time, if the internal resistance of the first MOS tube is small enough, the maximum output power is close to Ubat ^2/RL, wherein Ubat is the battery voltage, and RL is the resistance value of the heating wire.

When the microphone 12 outputs a low level, i.e., a second level, to the gate G of Q1, Q1 is turned off, and the power module 200 stops supplying power to the heating element 300.

In the embodiment, a simple circuit structure is adopted, namely, a MOS tube is added to realize high-power output.

In fig. 3, the switch module 11 includes a first MOS transistor Q1 and a second MOS transistor Q2, where the first MOS transistor is an NMOS transistor and the second MOS transistor is a PMOS transistor in this embodiment.

Specifically, the positive electrode of the power module 200 is connected to the source S of the second MOS transistor Q2, the drain D of the second MOS transistor Q2 is connected to one end of the heating element 300, and the negative electrode of the power module 200 is connected to the source S of the first MOS transistor Q1 and to the other end of the heating element 300.

Further, a resistor element R1 is connected between the source S and the gate G of the second MOS transistor Q2.

When the microphone outputs a high level, i.e. a first level, to the gate G of the first MOS transistor Q1, Q1 is turned on, so that the gate G of the second MOS transistor Q2 is grounded, and then Q2 is turned on, i.e. the power module 200 and the heating element 300 are turned on, and the power module 200 supplies power to the heating element 300, so that the heating element 300 generates joule heat. If the internal resistance of the second MOS tube Q2 is small enough, the maximum output power is close to Ubat ^2/RL, wherein Ubat is the battery voltage, and RL is the resistance value of the heating wire.

When the microphone outputs a low level, i.e., a second level, to the gate G of the first MOS transistor Q1, Q1 is turned off, the gate G of the second MOS transistor Q2 is pulled high by the resistor R1, and Q2 is turned off, so that the power module 200 stops supplying power to the heating element 300.

In this embodiment, the combination of the NMOS transistor and the PMOS transistor is used to realize high power output.
