Abstract: An air guiding device, an air conditioner indoor unit, and an air-conditioning system are provided. The air guiding device has an air guiding part used for guiding a flow of air blown out of an air outlet of the air-conditioning system. The air guiding part is rotatable, so as to change an angle used by the air guiding part for guiding the flow of air. At least one side of the air guiding part, which is in an airflow flowing direction, is provided with a flow straightening grid.

Abstract: Disclosed are an air intake mechanism and a negative pressure system. The air intake mechanism includes a first air intake end, a first air outlet end, and a first passage provided between the first air intake end and the first air outlet end, a first air driving unit is provided on the first passage, a first filter assembly is provided between the first air intake end and the first air driving unit, and a second filter assembly is provided between the first air outlet end and the first air driving unit.

Abstract: Disclosed are a hermetic tarpaulin device and a nursing room. The hermetic tarpaulin device includes a frame and a tarpaulin body. The frame can be unfolded or folded into a predetermined shape. The tarpaulin body can be connected to the frame. When the frame is unfolded, the tarpaulin body is unfolded to form a hermetic space completely isolated from an outside world, and when the frame is folded, the tarpaulin body is folded into a whole. The tarpaulin body can be unfolded with the frame to form a hermetic space completely isolated from the outside world, which can achieve complete isolation from the outside world, thereby improving the isolation effect, and the nursing room can be more convenient to build, and can also reduce the cost and reduce the occupied space.

Abstract: Disclosed is an air conditioning device, including a telescopic main structure, a ventilation air conditioning assembly and a control assembly, the ventilation air conditioning assembly is installed on the main structure, the main structure is configured to form a hermetic space inside it, and is configured to stretch or fold the hermetic space. The ventilation air conditioning assembly is configured to form a differential pressure environment in the hermetic space, the control assembly can be used to control the main structure to stretch or fold, and control the ventilation air conditioning assembly to adjust an air pressure, a temperature and a humidity in the hermetic space.

Abstract: An air conditioner indoor unit includes a chassis, an air duct assembly detachably connected with the chassis, a face frame including a detachment opening configured to allow the air duct assembly to pass through, a first panel configured to open or close the detachment opening, and a second panel configured to cooperate with the first panel to cover a surface of the face frame.

Abstract: An air conditioner indoor unit includes an air outlet frame, a front water receiving tray, and a panel. The air outlet frame includes an upper enclosure plate, a lower enclosure plate, and a side enclosure plate located between and connecting the upper enclosure plate and the lower enclosure plate. The front water receiving tray is above the upper enclosure plate and includes a protrusion section protruding out of the side enclosure plate and a water outlet hose at the protrusion section. The water outlet hose is configured to be received in a receiving cavity formed below the protrusion section and opening forward. The panel includes a cover member configured to cover the receiving cavity when the panel is in a closed state.
