Abstract: Methods, apparatuses, and storage mediums are provided for detecting water shortage for a humidifier. The method includes: obtaining a water level parameter of a water tank; determining a water level state of the water tank according to the water level parameter. When the water level state of the water tank is a water shortage state, energizing a valve connected to a water box so that water can be added to the water tank through the valve. A number of times of energizing the valve is recorded. When the number of times of energizing the valve exceeds a first preset number of times as well as when the water level state of the water tank determined every time after energization of the valve is the water shortage state, confirming that the water box is short of water.

Abstract: A water controller and a water controlling method are provided. The water controller includes: a water tank having a first water outlet; a magnetic control assembly; a water trough having a water inlet, the first water outlet being connected with the water inlet via the magnetic control assembly; an electromagnet configured to switch between a power-on state and a power-off state; wherein when the electromagnet is in a power-on state, a path between the first water outlet and the water inlet is in a connected state under control of the control assembly; and when the electromagnet is in a power-off state, the path between the first water outlet and the water inlet is in a blocking state under the control of the control assembly.

Abstract: The present disclosure relates to a power line assembly and an electronic device using the power line assembly. The power line assembly may include: a power line; a power plug disposed at a first end of the power line and configured to couple with a power outlet; and a power line base disposed at a second end of the power line and having a top surface and a bottom surface, each of the top and bottom surfaces having one or more power-delivery contacts, wherein when the power line base couples with a power-receiving assembly of an electronic device, at least one of the power-delivery contacts contacts with a power-receiving contact of the power-receiving assembly, to deliver power to the electronic device.

Abstract: A blower device for use in an air purifier is disclosed. The blower device includes a first fan and a second fan which have a same air blowing direction and are arranged sequentially in the air blowing direction at an interval. The first fan and the second fan are mounted coaxially and driven synchronously by a motor.
