The present application discloses a battery inspection device. The battery inspection device includes a power supply device, at least one charging port disposed on a surface of the power supply device, at least one display light bar disposed on the surface of the power supply device, and at least one first battery connection line, wherein the first battery connection line is electrically connected to the charging port.

Battery inspection device

Disclosed is an air purifier with an ambient lamp. The air purifier includes an upper housing, a lamp belt, and a lower housing, where a bottom edge of the upper housing is provided with a fixing recess matching the lamp belt in shape, the lower housing includes a base and a supporting plate vertically arranged at a preset position of the base, and the base is fixedly connected to a bottom of the upper housing, such that one end of the supporting plate away from the base presses the lamp belt in the fixing recess, and the lamp belt is arranged opposite an edge of the base at an interval. According to the present invention, the lamp belt is fixed to the bottom of the upper housing, and the lamp belt and the base of the lower housing are arranged at an interval.

Air purifier with ambient lamp

A lift device and a lift system are provided, which comprises: a carrying mechanism including a guiding hole; a lift pin passing through inside the guiding hole; a carrying base, which is connected to the lift pin, wherein when the carrying base is moved upward, the lift pin is moved upward and inside the guiding hole; and a magnetic control device, which is used to send a magnetic control signal, so as to move the lift pin downward. By the lift pin being moved downward and magnetically sucked, a bad process problem and a break risk can be avoided.

Lift device and lift system for substrate loading platform

Disclosed are a high-voltage protection circuit, a high-voltage protection method and a power supply. The high voltage protection circuit comprises a main relay, an auxiliary relay, a first resistor, a second resistor, a first capacitor and a second capacitor, wherein one end of the main relay is connected to the input port of a live line, and the other end thereof is connected to the output port of the live line; one end of the auxiliary relay is connected to the input port of the live line, and the other end thereof is connected between the first resistor and the second resistor; one end of the first capacitor is connected to the output port of the live line, and the other end thereof is connected to a neutral line parallel to the live line; the second capacitor is connected to both ends of the main relay in parallel; and the second resistor and the first resistor are connected between the input port and the output port of the live line in series in sequence. The present invention can effectively solve the problem that quick recovery cannot be achieved in an energy-saving mode, so that the system achieves high efficiency and energy saving, and can ensure high-voltage protection in an energy-saving mode through the bridge connection of the second capacitor to both ends of the main relay, and the adjustment of the capacitance values of the first capacitor and the second capacitor.
