The present application relates to the field of semiconductors and discloses a cleaning device and a cleaning method. The cleaning device comprises a bearing mechanism for supporting an object to be cleaned in a preset direction, and a cleaning mechanism for cleaning the object to be cleaned, the cleaning mechanism comprising a base and a first cleaning member detachably disposed on the base. The first cleaning member comprises a housing for detachably connecting with the base and a first brush head portion disposed on the housing, an accommodating space being formed and surrounded by the housing and the first brush head portion. A second cleaning member is further disposed on the base, the second cleaning member being accommodated in the accommodating space.

Devices and methods for cleaning an array of solar panels in side-by-side relation employ one or more elongated flexible elements, preferably implemented as translucent strips (14a, 14b, 14c, 14d), anchored at their ends relative to the array of solar panels (12). Each strip spans two or more solar panels, and is wind-displaceable so as to contribute to cleaning of at least two of the solar panels (12).

Textile fibers at least partially coated with a coating that includes particles of metal-organic frameworks dispersed in a polymeric base are provided. Also provided are fabrics formed from the textile fibers, protective gear and articles of clothing made from the fabrics, and methods of using the fibers and fabrics to catalyze the hydrolysis of organic molecules, such as organophosphate-based nerve agents, having hydrolysable bonds.

A method and a dishwasher capable of analyzing the closure state of the filter of the dishwasher by using a deep neural network model trained through machine learning of artificial intelligence is provided. The dishwasher may include a microphone configured to obtain a drainage sound signal generated by draining washing water through the filter during operation of the dishwasher, a processor configured to analyze the degree of closure of the filter based on the drainage sound signal, and an alarm generator configured to generate an alarm if the degree of closure is a greater than or equal to a predetermined level. The operational state of the dishwasher may be analyzed based on a drainage sound of the washing water drained to the filter by the degree of closure of the filter.

The present disclosure provides an electric steam control method, a system thereof, and a steam cleaner. The method includes: obtaining current water temperature data of a hot water tank and a current power supply mode; determining whether a temperature corresponding to the current water temperature data is within a preset temperature range; and if the temperature is within the preset temperature range, entering a heat preservation mode, else detecting whether AC power is currently available; if the AC power is available, performing power supply using the AC power, else generating a water temperature alarm signal; and in the heat preservation mode, detecting whether a working state is currently in place; if the working state is in place, detecting whether the AC power is currently available and generating a steam ejection signal, and performing power supply by using the AC or DC power, else maintaining the heat preservation mode.

A liquid treatment apparatus includes a water pump and a plasma jet generating device. A liquid inlet of the water pump is immersed in a liquid. A liquid outlet of the water pump is configured to eject the liquid from the liquid inlet out of the water pump without artificial bubbles in the liquid. A gas inlet of the plasma jet generating device is configured to be located out of the liquid. A pair of electrodes of the plasma jet generating device is configured to generate plasma jet by the gas from the gas inlet. The plasma jet outlet is configured to be immersed in the liquid and in proximity to the liquid outlet of the water pump so that the gas is automatically entrained into the gas inlet of the plasma jet generating device when the liquid is ejected out from the liquid outlet.
