Abstract: The present disclosure discloses a bidirectional flipping mechanism for flipping a TV cabinet and a flip TV cabinet. The bidirectional flipping mechanism includes a driving unit mounted on a mounting base for driving at least one of a first flipping member and a second flipping member to respectively pivot around a first pivot shaft and a second pivot shaft with respect to the mounting base, and thus when the bidirectional flipping mechanism is applied to the flip TV cabinet, an upper part of a vertically placed laser TV on the support plate and the top of the support plate can be as close as possible to the top plate of a cabinet body of the flip TV cabinet, so as to reduce a total height of the cabinet body and avoid a large gap between the support plate and the top plate.

Abstract: A photocatalytic honeycomb assembly and a photocatalytic purification apparatus, which can maximally increase a contact area between polluted air and a photocatalyst while maximally ensuring that the surface of the photocatalyst receives sufficient irradiation of ultraviolet light, and can also make the flow resistance to air flowing in a channel meet requirements in the field of ventilation systems which have high requirements on flow resistance. The photocatalytic honeycomb assembly is formed of one or more photocatalytic honeycomb cores and a photocatalytic honeycomb assembly housing. The one or more photocatalytic honeycomb cores are arranged in a honeycomb form. The photocatalytic honeycomb core is formed of three or more basic core units and a light guide member that is Y-shaped in an end view.
