A device has a container for a substance to be dispensed. A wick as a capillary element in contact with the substance in the container and forms part of the container. The wick has a wick-side substance dispensing area. A heating element produces a substance air flow, which is enriched with substance and flows away from the device, by heating the wick-side substance dispensing area and a substantially substance-free hot air flow that flows away from the device and is warmer than the substance air flow, by heating the air surrounding the heating element. A flow-guiding and/or deflecting apparatus guides and/or deflects at least one of the air flows, preferably the substance-free hot air flow, such that the air flows hit each other, preferably at a defined angle of incidence, and form a common substance-and-hot-air flow flowing away from the device.

An insect trap having a base portion, which has a lighting element and a housing portion, and a trap portion. The trap portion has a frame and a membrane, which has an adhesive surface, is at least partially contained within the frame, and is configured to adhere to an insect. The housing portion is configured to receive and retain the trap portion when engaged therewith.

A mosquito repeller includes a casing, a mosquito repellent liquid bottle, and a first heating element installed in the casing. The first heating element includes a first heat-generating body and a cotton swab. The first heat-generating body is inserted into the cotton swab, and an end of the cotton swab away from the first heat-generating body extends into the mosquito repellent liquid bottle. Since the first heat-generating body is inserted into the cotton swab, heat is concentrated at the center of the cotton swab, and the cotton swab is heated uniformly, and the vaporization of the mosquito repellent liquid is stable to improve the mosquito repelling effect of the mosquito repeller, while reducing the power consumption of the mosquito repeller, saving energy, avoiding a temperature rise of components near the heat-generating components, retarding the ageing of components, and extending the service life of the mosquito repeller.

A volatile material dispenser includes a base and a stand assembly that is coupled with the base. The base includes a fan and a battery therein. The stand assembly includes a platform, a stand that extends from the platform, and a manifold that extends from the stand. The volatile material dispenser also includes a shroud and an air deflector. The shroud is positioned on the base and defines a chimney. The air deflector is positioned between the shroud and the manifold. The air deflector is configured to direct air out of the chimney.

An insect repellent device has a housing that fits onto a liquid repellent reservoir. The housing may have a heater for volatilizing the liquid insect repellent.

A composition includes a gel carrier having a gel phase at a first, ambient temperature and a liquid phase at a second, higher temperature, and an insect repellent chemical in the carrier. The repellent chemical has substantially no volatilization from the gel carrier when the gel carrier is in the gel phase, but volatilizes from the gel carrier when the gel carrier is in the liquid phase.

A volatile material dispenser comprises a base that houses a printed circuit board. The base includes at least one button and a plurality of visual indicators along a front portion. The volatile material dispenser further comprises a stand assembly that is coupled with the base. The stand assembly includes a platform defining a front portion and a rear portion, a stand that is disposed above and on the rear portion of the platform, a manifold that is disposed at an upper end of the stand and defines an outer side surface from which extends a plurality of radially spaced ribs, and a piezoelectric assembly disposed within the manifold. The volatile material dispenser further comprises a cover that is configured to be attachable to and detachable from the base. The cover defines a chimney that defines a longitudinal axis. The manifold includes a refill chassis.

A scent vaporizing and distribution device uses an electric heating element to rapidly vaporize a liquid scent material. An airflow generator is used to create a distribution airflow that distributes the vapor from the device. The airflow generator can be an electric-powered fan or a manually-powered pump or squeezable bladder. The liquid scent material can include a glycol or a water-glycol mixture. A scent material such as liquid or powdered deer urine or a pleasant scent that can be used as a room or automobile or room freshener is mixed with the liquid. The vapor generator can be removable and replaceable such that different scents can be used with a single airflow generator or an empty generator can be replaced.

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.

A device for evaporation of volatile substances, comprising a housing; a container removably mounted in the housing containing liquid volatile substances; a wick of a porous material, provided with a first end and a second end, wherein at least the first end is contained inside the container; a resistor element arranged to contact the second end of the wick; and connecting means for connecting the device to the mains supply to allow the heating of the resistor element; wherein the resistor element is a coiled wire that forms a compressing spring, and wherein the resistor element is compressed and in contact with the second end of the wick when the container is mounted in the housing.
