A vibrating piezoelectric atomizer comprising: a piezoelectric tube having a length, a first end defining an opening and a second end, the second end of the piezoelectric transducer tubular body is connected to a horn; the horn is dimensioned to be half wavelength resonator; the horn is folded and located alongside the piezoelectric tube; a metallic disk is connected to the horn near the first end of the piezoelectric tube, whereby by applying an alternating voltage across electrodes of the piezoelectric tube, the piezoelectric tube is excited into a resonant vibration when frequency of excitation equals to half wavelength resonant frequency of the piezoelectric tube's length and vibrates in synchronism and is communicated to the metallic disk to atomize a liquid.

An aftertreatment system for treating constituents of an exhaust gas produced by an engine, comprising: a housing; a selective catalytic reduction (SCR) system disposed within the housing; a reductant injector disposed on a sidewall of the housing upstream of the SCR system and configured to insert a reductant into the exhaust gas; and a vortex generator disposed in the housing, the vortex generator comprising at least one deflector disposed on a surface within the housing, the at least one deflector configured to generate vortices in a portion of the exhaust gas flow flowing over the at least one deflector such that the portion of the exhaust gas remains attached to the surface at a downstream location of the surface.

The humidifier includes a humidification section which vaporizes water to produce humidified air, and a fan which produces in an air passage an air flow delivering the humidified air to the outside. The humidifier further includes a sterilized water producing section which produces sterilized water, an ultrasonic irradiator which produces sterilizing mist through ultrasonic irradiation of the sterilized water, an auxiliary passage through which the sterilizing mist is delivered to the outside, and an operation switching mechanism. The operation switching mechanism is switched between a first operation mode in which the air passage and the auxiliary passage communicate with each other to introduce the sterilizing mist into the air passage, and a second operation mode in which communication between the air passage and the auxiliary passage is blocked.

An ultrasonic humidifier according to an embodiment of the present invention includes: a water bottle accommodating water capable of generating humidification; a water bottle lid covering an upper opening surface of the water bottle and including a humidification outlet for discharging the humidification; and an ultrasonic humidification generating module which floats submersibly in the water accommodated in the water bottle and generates humidifying particles by using ultrasonic waves.

An aerosol-generating system includes an aerosol-generating device and at least two consumables. Each consumable includes an aerosol-forming substrate. The aerosol-generating device further includes a device housing comprising at least two receiving chambers, wherein each consumable is accommodated in a separate receiving chamber of the at least two receiving chambers. The aerosol-generating device further includes at least two mouthpieces, wherein each mouthpiece of the at least two mouthpieces is aligned with a separate consumable of the at least two consumables and wherein the aerosol-generating device is configured to isolate airflows through separate, respective mouthpieces of the at least two mouthpieces.

A decorative humidifier is provided that utilizes the structural features of common houseplants in a new and advantageous ways by providing stalks or stems to form hollow water vapor conduits for humidifying vapor. A planter conceals a water source for the humidifier. Flowers at the end of the stems may serve as water vapor exits. Particular plants may be chosen for advantageous features, such as long and numerous stems and flowers that may serve as an inconspicuous vapor exits. A drying unit may be connected to the vapor tube in order to force dry air through vapor channels to prevent growth of microbes and accumulation of deposits. The natural features of a chosen plant are utilized to create a synergy between aesthetics and function in a decorative humidifier.

An air conditioner includes a humidifying assembly and a control unit to control the humidifying assembly. The humidifying assembly includes a humidifying-receiving unit including a water tank configured to receive water and a humidifying-sterilizing unit configured to irradiate light to sterilize water received in the water tank. The control unit is configured to control a driving time of the humidifying-sterilizing unit based on an amount of water received in the water tank.

A container structure for a floating type humidifier according to the present disclosure, in which the floating type humidifier is installed to be movable in a state in which the floating type humidifier floats on water stored in an accommodating space, includes: a lower body which has therein the accommodating space opened at an upper side thereof, and has a lower surface that is horizontally formed and seated on an installation surface; and an upper body which has a lower end that is correspondingly coupled to an upper end of the lower body, and an upper end that is formed to be bent toward the accommodating space so as to have a curved surface, and allows water flowing in a lateral direction by external force to flow back into the accommodating space.

Provided is a humidifier, including a machine base, a water tank, a water suction pump, and a water inlet pipe. The machine base is located on the water tank, which includes an atomization water reservoir, a water feed base, a control base, an atomization air channel and an atomizer disposed inside. The water feed base includes a water feed opening and a first outflow opening, and the first outflow opening is in communication with the water tank; a water inlet is disposed on the atomization water reservoir, and water in the water tank will flow into the atomization water reservoir through the water inlet pipe by the water suction pump; the atomizer is in communication with the atomization water reservoir through an atomization opening disposed at the atomization water reservoir, and water vapor flows into the atomization air channel and flows to outside along the atomization air channel.
