A dry diffuser is disclosed which avoids safety and transport issues typical of liquid diffusers, candles and wax melts and provides systematic controlled diffusion of fragrance (or other active material) over relatively long periods with a programmable user interface.

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 device for mosquito repellents, including a support structure having a first end arranged to be positioned on a surface, and a second end opposite the first end, the distance between the first end and the second end defining a height H of the support structure. The device further includes a first plate arranged at the second end of the support structure perpendicularly to a direction of height of the support structure, the plate being void of openings and suitable for receiving a heated mosquito repellent. The device still further includes a fan attached within the support structure, between the first end and the second end of the support structure, to blow air from the first end towards the second end of the support structure and the first plate, and means for operating the fan. The size and shape of the first plate is such that it covers the fan, when seen from the second end of the support structure in the direction of height of the support structure.

Oxalic acid vaporizer with integral body tube, detachable proximal end air nozzle, and floating heating element is a pest control vaporizer or pesticide vaporizer that is used to protect bees from certain pests, mites, and insects where the pesticide vaporizer expels a vapor that kills harmful pests, mites, and insects but does not harm or affect bees in the colony. Oxalic acid vaporizer with integral body tube, detachable proximal end air nozzle, and floating heating element includes an integral body tube that is without any holes, perforations, punctures, gaps, vents, or discontinuities. Oxalic acid vaporizer with integral body tube, detachable proximal end air nozzle, and floating heating element includes a detachable proximal end air nozzle. Oxalic acid vaporizer with integral body tube, detachable proximal end air nozzle, and floating heating element includes a floating heating element with a floating electrical connection.

An air supply device with air refreshing and insect repellent function include a housing, which comprises: an air duct unit supported inside the housing having a hollow body defining an air channel; a centrifugal fan received inside the air duct unit; two main air inlets arranged at two opposite sides of the housing; an air outlet arranged at a top portion of the housing and channeled through with the air channel inside the air duct unit at a front side of the housing perpendicular to each of the main air inlets; an auxiliary air inlet arranged at a rear side of the housing opposite to the air outlet; an auxiliary component, which is an aromatherapy component or a mosquito repellent component, connected to the housing at the auxiliary air inlet; and an optional heating component detachably connected to the housing at the main air inlet.

The invention relates to a device for dispensing and/or diffusing volatile substances, comprising a housing (32), a storage tank (33) and an electrical heating device (30). The device further comprises a capillary element (34) which is coupled to the heating element in a heat-transferring manner, the capillary element (34) having a substance-receiving area (35) which is in contact with a substance received in the storage tank (33) and which substance is conveyable to a substance-discharging area (36) of the capillary element (34) at which the substance is dispensed. Furthermore, an air inlet (50) is provided, by means of which ambient air (53) enters from outside the housing (32) and forms a pure air flow (40) in the housing interior. An air duct (54) is provided which, starting from the air inlet (50), extends as far as the substance discharging area (36), at which a substance air flow (51) enriched with substance is generated, and which, starting from the substance discharging region (36), is led to an air outlet (38) via which the substance air flow (51) is discharged to the environment. In addition, a control device (39) is provided, by means of which the electrical heating device (30) can be controlled, preferably at intervals.

A volatile composition dispenser and a method of dispensing a volatile composition is provided. The volatile composition dispenser includes a reservoir for containing a volatile composition and a transport member having a first end portion and an opposing second end portion, and an evaporative surface. The first end portion of the transport member is in fluid communication with the reservoir and the second end portion of the transport member is in fluid communication with the evaporative surface. The volatile composition dispenser also includes an air pump in gaseous communication with the reservoir.

A fragrance delivery device, system, and method of use and manufacturing are disclosed. The device has a vapor releasing membrane including a plurality of micropores, wherein each respective micropore has a consistent diameter dimension in both a delivery condition and in a use-condition of the fragrance delivery device. The device further includes a flexible impermeable barrier coupled to the vapor releasing membrane along a perimeter thereof, wherein the vapor releasing membrane and impermeable barrier define a cavity there between having a predetermined volume. A substance is disposed in the cavity up to the predetermined volume, the substance comprising a volatile fragrance disposed in a matrix, wherein the substance has a first viscosity in the delivery condition and a second viscosity in the use-condition, the volatile fragrance being releasable from the matrix when exposed to a predetermined temperature and emittable through the plurality of micropores.

A device for dispersing in the air in the vapor state and a substance that is in the liquid state at ambient temperature, and is contained in a storage container, has a ventilation system with a duct that opens out into the open air and is configured to permit the passage of a flow of air into the duct; at least one dispensing unit is designed to be supplied with a liquid substance by the storage container, the dispensing unit having micro-ducts forming an outlet is provided in the duct in order to constitute an area of evaporation of the substance therein, and a heating unit is provided on or in the dispensing unit, such as to control a flow of the substance through the dispensing unit.
