The present application provides an intelligent air purification robot with a mosquito-repelling function. In the present application, a robot body has an obstacle detection function and can make a turn automatically. That is, the robot body can automatically find a path after being placed in a room, and can purify air everywhere in the room. Dust-laden air enters a housing from an air inlet and is then treated by a plurality of modular units. Moreover, a UV lamp is further provided, so that air can be disinfected at a designated position.

A scent dispenser may comprise a vial retaining mechanism, a heating element, vial sensor, and a controller. The vial retaining mechanism includes a vial coupling that removeably retains a vial containing a scented solution. The includes a wick extending from a cavity of the vial through an opening of a neck of the vial. The heating element is shaped to receive and heat the wick of the vial. The vial sensor includes an array of sensor pads that are arranged in alignment with the vial retained by the vial coupling. The controller is electrically coupled to the heating element and electrically coupled to the array of sensor pads. The controller regulates a temperature level of the heating element, and receives signals from the array of sensor pads and processing the signals to determine a fluid level of the vial.

A volatile material dispenser includes a housing configured to receive a refill containing a volatile material and a wick, the housing including a first cavity supporting a heater arrangement and a second, separate cavity supporting a fan arrangement for dispersing a vapor plume of the volatile material. The first cavity is substantially unobstructed between an upper, interior surface of the housing and an upper surface of the heater arrangement. The housing also includes an aperture through which the vapor plume exits the housing and a plurality of openings through which air from the fan arrangement directs the vapor plume away from the aperture. When a refill is received within the hosing, the upper surface of the heater arrangement is disposed nearer the aperture than a distal end of the wick, and a radial gap is formed between the heater arrangement and the wick.

A scent diffusing device having a first housing connected to a second housing and adapted to provide electrical power to a heating element disposed within the second housing. A cap assembly is removably attached to the second housing. The cap assembly has a support member removably attached to a cover, and a fragrance emitting member removably received within the support member. The support member has a central hollow tube that slidably receives the heating element.

An air scenting assembly includes: a scent container which at least initially contains a scent perfume, and a scent perfume extracting mechanism, which is configured to release scent perfume from the scent container. The scent perfume extracting mechanism includes a scent perfume absorbing element insertable into said scent container, a scent carrying material, a dripping mechanism arranged onto said scent perfume absorbing element, said dripping mechanism is configured to deposit scent perfume from the scent container onto said scent carrying material, and a limiter to restrain extraction of scent perfume from the scent container, wherein the limiter comprises an air duct between the scent perfume absorbing element and the dripping mechanism, and the limiter is air flow controlled, wherein one end of said air duct is placed inside said scent container, and wherein the other end of said air duct is connected to a nozzle, said nozzle being arranged on said scent carrying material so that when said scent carrying material is drenched to saturation, no more air can pass through said scent carrying material and up into said nozzle and said air duct, and so that when the scent carrying material is dry enough passage of air through said air duct is allowed.

A compact diffuser integrates an atomizer and droplet separator into a surrounding sleeve, threadable to a bottle neck as an assembly. The assembly fits into a base, housing a motor and air pump, sealing the sleeve to a silo in the housing. Controls set time span of intermittent operation, intervening delay, and volumetric flow rate. The assembly pops into (and out of) the top end of a silo in the base, registering (aligning) circumferentially and axially to seal an air path from the pump to the atomizer. Access for applying force to the bottom of the assembly facilitates popping out the assembly when empty, or to simply change scent by changing out the assembly. Entire assemblies may be stored to simplify exchange and reduce chances for spills from reservoirs.

A disinfecting unit and method of operating the same includes a cabinet having a vertical axis, a first lamp coupled to the cabinet directing light in a generally radial direction relative to the vertical axis, a second lamp coupled to the cabinet directing light in at least a partially axial direction relative to the vertical axis and a nebulizer that dispenses disinfecting fluid therethrough.

A controllable scent sample dispenser has a microdosing device for outputting, during an activation state, a scent sample at a scent sample outlet to the environment, wherein the microdosing device is placeable adjacent to an animal's nose so that a distance between the outlet of the microdosing device and a nare or nostril of the animal's nose is within a predefined range, and a microdosing driver unit for adjusting a dosing rate of the scent sample output at the scent sample outlet by selectively activating the microdosing device.
