Discussed is a surface type heating element including a surface type heating element layer including NiCr alloy powders, necks between powder particles of the NiCr alloy powders, and passivation oxide layers formed on a surface of the NiCr alloy powders.

The present invention is directed to an autonomously powered vapor dispensing device comprising an intermediate basin which allows the volatile liquid contained therein to impregnate a dispensing material by capillarity and dispense into the atmosphere; and a heating element which heats the intermediate basin comprising the volatile liquid to force evaporation cyclically of the volatile liquid directly from the intermediate basin.

The present disclosure relates to an aerosol generating device and a heating assembly. The heating assembly includes a heating portion configured to generate infrared light waves in a power-on state and a sleeve for the infrared light waves to pass through. The heating portion includes a heating substrate, an antioxidant layer arranged on the outer surface of the heating substrate and configured to prevent the heating substrate from being oxidized, and an infrared radiation layer arranged on the side of the antioxidant layer away from the heating substrate. An accommodating cavity configured to accommodate the heating portion and non-sealed is formed in the sleeve. In the heating assembly, with the antioxidant layer, the sleeve's accommodating cavity doesn't require sealing, vacuuming, or inert gas filling. This simplifies the assembly process and cuts manufacturing costs.

An aerosol generation device includes: a housing comprising a side wall and a bottom wall, an accommodation cavity being jointly delimited by the side wall of the housing and the bottom wall of the housing; a heating assembly accommodated in the accommodation cavity, the heating assembly emitting a laser to heat an aerosol generation substrate; and a heat dissipation assembly accommodated in the accommodation cavity, the heat dissipation assembly including a main body member, the main body member including a mounting portion and an abutting portion. The heating assembly is mounted at the mounting portion. The abutting portion is closer to the side wall of the housing than the mounting portion so as to dissipate heat from the heating assembly.

The invention related to a sensing system comprising an electrowetting device, which electrowetting device comprises an array of actuation electrodes, and a control system configures to perform droplet operations on a system of droplets present in the sensing system. The invention also relates to a method of operating the sensing system of the invention. The invention also provides novel droplet constructs which can be made and manipulated in the sensing system of the invention.

A heating element can be moved by a machine, such as a machine including a fan, an actuator, or a conveyor. The heating element can be attached to or embedded in a fan or an actuator. Or, the heating element can be attached to or embedded in a conveyor belt of a conveyor. A combination of a heating element and a mover machine can be further combined with a heat radiating wall. The heating element and the machine can be arranged behind the wall. And, when the heating element and the machine are powered on, the heating element converts electrical energy into heat, which increases the temperature of the wall, and the machine moves the heating element to be next to different areas of the wall. This allows for heat to be distributed more evenly to the wall than it would be if the heating element did not move.

An aerosol-generating device is disclosed. The aerosol-generating device includes a storage chamber storing an aerosol-generating substance, a wick that is in communication with the storage chamber, a heating element that is in contact with the wick and contains nanoparticles generating heat through surface plasmon resonance, and a light source configured to emit light toward the heating element. The heating element includes a first part receiving light emitted from the light source and a second part disposed outside the first part and having a plurality of holes formed therein.

This application provides an aerosol generation device and a control method thereof. The aerosol generation device includes, a housing, provided with a through hole and an air inlet; a cavity, where an aerosol-forming substrate is received in the cavity or removed from the cavity through the through hole; a heater, configured to heat the aerosol-forming substrate received in the cavity; a heat drain device, arranged on a gas flow path extending between the air inlet and the through hole; and a circuit, configured to, after the heater starts for heating and before the heater enters an inhalation stage, control the heat drain device to start operation to drain hot air generated by heating out of the housing along the gas flow path. Before a smoker inhales on the aerosol generation device, the heat drain device drains an aerosol comprising vapor out of the housing.

A heat lamp is provided that minimizes visual obstructions between an individual and a food service line, while more evenly distributing heat across food. The heat energy penetrates into the food and does not merely heat the surface. Different heating capabilities can be provided by locating the lamp head at different positions over a large adjustable height range. Additional lighting elements provide illumination to heated surfaces to improve visual appeal. Each heat lamp on a service line may be connected to an adjacent heat lamp through built-in power receptacles. The surfaces of the heat lamp are sealed and/or made of easily cleaned substances and have features compliant to one or more industry standards. The heat lamp may be easily transportable and may be resistant to damage.
