A portable air purifier may include an inlet configured to form a path along which air is suctioned, a filter disposed at an upper side of the inlet and configured to purify air which enters through the inlet and moves upward, a sanitizing portion disposed at a lower side of the filter, installed at a height allowing the sanitizing portion to overlap the inlet, and configured to irradiate sanitizing light toward the filter, and a fan module disposed at an upper side of the filter and configured to rotate a fan to blow air in a direction toward the upper side of the filter.

An air blower enables cold-air dehumidification by removing moisture in summer, can supply instantaneous hot air when the room temperature temporarily goes down, enables hot-air humidification by supplying moisture in winter, enables a four-season use by using an additional humidification function in spring and fall, controls room temperature and room humidity by providing an indoor temperature/humidity sensor and a water temperature sensor, saves energy by intelligently operating and stopping all the functions, provides warning signs through lamps for indicating supply or discharge or lack of water with a high/low water level gauge of a water tank and a high water level gauge of a water tank for dehumidification, prevents safety accidents such as damage or conflagration and the like of components related to a fan driving motor by providing a fan driving motor overheating prevention sensor, prevents the leakage of water when a main body falls down.

A dehumidifier system is provided. The dehumidifier system may include a condensate tank and a dehumidifier. The dehumidifier may be positionable between at least one deployed position and at least one stowed position relative to the condensate tank. The condensate tank and the dehumidifier may telescope relative to each other. The dehumidifier system, or portions thereof, may include one or more stacking structures.

A dehumidifier with a nesting sensor is provided. The dehumidifier system includes a condensate tank and a dehumidifier that may be positionable between at least one deployed configuration and at least one stowed configuration relative to the condensate tank. The stowed configuration has the apparatus nested within an internal volume of the condensate tank. The dehumidifier system includes a protuberance on the bottom of the condensate tank to activate a switch of the dehumidifier, and a magnet on the bottom of the condensate tank to activate a Hall-effect sensor of the dehumidifier.

A lift mechanism and air supply device with lift mechanism, the lift mechanism includes a cylinder, a threaded rod rotationally arranged in the cylinder, a power source for driving the threaded rod to rotate and a threaded holder in threaded connection with the threaded rod, the threaded holder is configured to install the air supply mechanism, a space is formed between the support bracket and the threaded holder, one end of the threaded rod extends between the support bracket and the threaded holder, and a guiding element for preventing the threaded holder from rotating is arranged between the cylinder and the threaded holder.

An air handler unit for use with residential heating, ventilation, and air conditioning (HVAC) systems. The air handler unit has high resistance mediums (HRMs) coupled closely to a wide-angle vane-diffuser mixed-flow fan system. The HRMs are placed immediately upstream and downstream of the wide-angle vane-diffuser mixed-flow fan to form a closely coupled, compact air handler that provides significant efficiency and noise benefits.

A mobile air conditioner includes an air duct assembly connected to an air duct fixing plate. The air duct fixing plate is arranged on and to close a window. The air duct fixing plate includes first and second sub-fixing plates, and an adjusting assembly. The first and second sub-fixing plates fit and slide relative to each other. The second sub-fixing plate includes a plurality of first locking portions. The adjusting assembly is connected to the first sub-fixing plate and selectively engaged with a second mounting plate. The adjusting assembly includes a locking member and a driving member. The locking member includes a second locking portion in locking fit with the first locking portion. The driving member includes a driving portion and a cam portion, which abuts against a side of the locking member facing away from the second locking portion, and the cam portion drives the locking member to move.
