[0054] Step S101: Obtain the first level information of the drive signal of the first drive circuit, the second level information of the drive signal of the second drive circuit, and the detection signal.

[0055] In this embodiment of the application, the electronic device can be connected to the output terminals of the first driving circuit, the second driving circuit, and the operational amplifier circuit, and directly detect the first level information of the driving signal of the first driving circuit, the second level information of the driving signal of the second driving circuit, and the detection signal from the detection circuit.

[0056] In this embodiment, the first level information and the second level information can be high level information and low level information, respectively. In this embodiment, a high level is applied when a control signal is input, and a low level is applied when no control signal is input. In this embodiment, the driving signal is a control signal.

[0057] Step S102: Determine whether the water tank has been lifted based on the first level information, the second level information, and the detection signal.

[0058] In this embodiment of the application, step S102 can be implemented through the following steps:

[0059] Step S1: When the first level information is low and the second level information is high, determine whether the detection signal is greater than or equal to the first preset voltage value.

[0060] Step S2: If the detection signal is less than the first preset voltage value, it is determined that the water tank has been lifted.

[0061] In this embodiment of the application, the humidifier operates normally when the detection signal is less than the first preset voltage value.

[0062] For example, with AD-UV as the first level signal and AD-W as the second level signal, since AD-UV is at a low level, the value of AD-UV is close to 0, while AD-W is at a normal value. Therefore, the detection signal VAM is VAM = (AD-W - AD-UV) * F.

[0063] In some embodiments, step S102 can be implemented by the following steps:

[0064] Step S3: When the first level information is high and the second level information is low, determine whether the detection signal is less than or equal to the second preset voltage value.

[0065] Step S4: If the detection signal is greater than the second preset value, determine that the water tank is lifted, wherein the first preset voltage value is greater than the second preset voltage value, and the second preset voltage value is greater than 0.

[0066] In this embodiment of the application, if the detection signal is less than or equal to the second preset voltage value, the humidifier works normally.

[0067] For example, the second preset voltage value can be represented by V4, and it can be determined whether VAM is less than or equal to V4.

[0068] In some embodiments, step S102 can also be implemented through the following steps:

[0069] Step S5: When the first level information is high and the second level information is high, determine whether the detection signal is less than the third preset voltage value and greater than or equal to the fourth preset voltage value.

[0070] Step S6: If the detection signal is greater than the third preset voltage value or the detection signal is less than the fourth preset voltage value, it is determined that the water tank is lifted, wherein the first preset voltage value is greater than the third preset voltage value, the third preset voltage value is greater than the fourth preset voltage value, and the fourth preset voltage value is greater than the second preset voltage value.

[0071] In this embodiment of the application, the humidifier is determined to be working normally when the detection signal is less than the third preset voltage value or the detection signal is greater than or equal to the fourth preset voltage value.

[0072] The inspection method provided in this application obtains a detection signal through the connection structure of the detection circuit, thereby enabling the inspection of whether the water tank of the humidifier is lifted based on the detection signal. It does not require the installation of a reed switch or a magnetic induction switch, thereby reducing the manufacturing cost of the humidifier.
