Abstract: A catalyst for hydrorefining crude terephthalic acid, as well as its preparation method and application are provided. The catalyst includes a support and active components. The active components contains palladium and ruthenium in a weight ratio of (3-10):1, on element basis. The palladium is Pd0, and ruthenium includes Ru0 and Ru4+. Ru4+ and Ru0 are in a weight ratio of 0.1-1.0. The catalyst may be particularly suitable for hydrorefining crude terephthalic acid.

Abstract: A foam local cleaning device and a washing machine, the foam local cleaning device including: a housing having a containing cavity; a foam cleaning component connected to the housing and movable relative to the housing, at least used to provide foam detergent during local cleaning, the foam cleaning component having a storage position and a cleaning position relative to the housing; and a signal transmission unit, which transmits a signal to the foam local cleaning device when the foam cleaning component moves to a set position. The signal transmission unit can reflect the position information of the foam cleaning component to ensure that the foam cleaning component is opened or closed in place. The foam cleaning component is switched between the cleaning position and the storage position by a transmission component, which not only reduces the space occupied by the foam cleaning component, but also protects the foam cleaning component.

Abstract: An atomizing generator, a clothing treatment device, and a control method therefor to solve the problems of the structural complexity and poor liquid level measurement accuracy of existing atomizing generators. The atomizing generator includes an outer shell and an atomizing module, an atomization cavity capable of accommodating liquid being disposed in the outer shell, and a liquid inlet, an air inlet, and a mist outlet in communication with the atomization cavity being arranged on the outer shell, the atomizing module including an ultrasonic atomizing sheet, and the atomizing module being arranged to be capable of atomizing the liquid in the atomization cavity by vibration of the ultrasonic atomizing sheet and detecting the height of the liquid level in the atomization cavity by the vibration, which simplifies the structure of the atomizing generator and increases the precision and accuracy of liquid level measurement.

Abstract: The present disclosure discloses a washing machine, including a washing drum, being a water containing tub during washing; a balancing ring, arranged on the washing drum; and a sealing structure, configured to prevent water from overflowing between the washing drum and the balancing ring. According to the washing machine, capacity of the washing drum can be expanded; and meanwhile, since the sealing structure is arranged between the washing drum and the balancing ring, water is prevented from overflowing out of the washing drum between the washing drum and the balancing ring, so as not to corrode a washing machine case or other components due to splashing as time goes, or not to cause short circuit.
