A hot air blower, according to the present invention, which can have the advantage of allowing the inside of a combustion body assembly (40) to be easily opened during a failure since the hot air blower has a structure for maintaining a coupled state when a service cover (80) is closed, and for rotating to an upper side only when the service cover (80) is opened.

A heat gun includes a head portion. The head portion defining a flow passage having an inlet end at one end and an outlet end at another opposite end, and including an inlet portion, an outlet portion and a flow guiding portion disposed between the inlet and outlet ends. The outlet portion is formed with two long sides and two short sides. The flow guiding portion is disposed between the inlet and outlet portions. The flow passage includes two flow guiding protrusions disposed at the flow guiding portion. The two flow guiding protrusions are disposed oppositely and extend oppositely along the long sides.

One or more techniques and/or systems are disclosed for a heating device may comprise a control assembly having a self-contained, on board power supply. A control unit may control the operation of the heater and the power supply may comprise a first power source in electrical communication with the control unit, wherein the control unit controls the operation of the first power source to selectively supply electrical power to at least a portion of the heating device; and, a second power source in electrical communication with the control unit, wherein the control unit controls the operation of the second power source to selectively supply electrical power to at least a portion of the heating device.

A heating apparatus for generating a hot air flow comprises a single fan, a burner heating element and a resistance heating element. In this respect, an air passage that conducts air to be heated and a combustion air passage that leads to a burner adjoin the fan downstream, wherein a combustion air flow in the combustion air passage can be controlled by a control element associated with the combustion air passage.

A portable battery operated heater powered by a battery includes a housing having an air inlet formed at a rear wall and an air outlet formed at a front wall, the housing further comprising an interiorly concave portion extending from the rear wall to the front wall, the interiorly concave portion directing a flow of air from the air inlet to the air outlet; a fan electrically connectable to the battery, the fan being disposed within the housing for creating the flow of air; and a heating element electrically connectable to the battery, the heating element being interposed between the air inlet and the air outlet in such manner that the flow of air passes over the heating element and is heated thereby.

A bladeless fan assembly for creating an air current includes a nozzle mounted on a base housing a device for creating an air flow. The nozzle includes an interior passage for receiving the air flow and a mouth for emitting the air flow. The nozzle defines, and extends about, an opening through which air from outside the fan assembly is drawn by the air flow emitted from the mouth. The nozzle also includes a heater for heating the air flow upstream of the mouth.

A centrifugal blower and heating element apparatus includes a base, a scroll housing having primary and secondary inlet ports, and an integrated heating element, motor and impeller. The apparatus may be provided as a portable appliance used for heating a room. The apparatus may have an elongated aspect ratio and a space efficient design.

The embodiments of the disclosure relate to an air treatment device comprising a housing. The housing is provided with an air inlet, a top of the housing is provided with an first air outlet communicated with the air inlet, and a side part of the housing is provided with a second air outlet communicated with the air inlet; and the housing is provided with a sealing structure, and the sealing structure moves relative to the housing to adjust opening and closing states of at least one of the first air outlet and the second air outlet.

According to an aspect of the present invention, a space heater having wireless charging capability, comprising: a space heater frame; a heating element; a power source; a wireless charging dock positioned within the space heater frame; a remote control; and a rechargeable battery positioned within the remote control, wherein the wireless charging dock is configured to charge the internal rechargeable battery positioned within the remote control.

A foldable space heater comprises a lower housing, a telescopic pole, and an upper housing. The upper housing connected with the telescopic pole via a first hinge joint. The lower housing connected with the telescopic pole via a second hinge joint. An electric wire passed through the lower housing towards the upper housing via the telescopic pole to avoid tripping of the electric wire. The upper housing includes a heating element, and a fan. The heating element connected with the electric wire to convert electric energy into heat. The fan ventilates the radiations associated with the heat. The telescopic pole makes the foldable space heater extendable and retractable. The first hinge joint and second hinge joint makes the foldable space heater collapsible. A user interface provided to operate the foldable space heater. The foldable space heater also equipped with wireless charging.
