This heating assembly comprises a thermally conductive tube (42), to be immersed in a thermally expandable material of a thermostatic element of a valve, an electric heating resistor disposed inside the tube and from which there extend electrically conductive wires (62), and a unitary housing (1) made from plastic, through which the fluid to be regulated flows via the valve, and which is secured by over-molding of a longitudinal end portion (44) of the tube. In order to make the molding of the over-molded housing simple and inexpensive to carry out, while being easy to adapt to various geometric forms of the heating assembly, the invention proposes that, before the housing is molded, a reinforcement (7) for supporting the wires outside the tube, which is separate from the housing, and to which the housing is secured by over-molding, can be securely mounted on the end portion of the tube and supports the wires outside the tube, said wires being externally mounted on the reinforcement, and, when the housing is being molded, keeps the wires in place while the plastic material of the housing coats these wires, the reinforcement and the end portion of the tube.

A concave portion, that is concave in a direction away from a back door glass, is formed at a facing wall of an outer member at a facing region that faces a bus bar portion. Due thereto, a gap between a bottom surface of the concave portion and the bus bar portion that is disposed at the back door glass can be made to be large.

An atomization assembly configured to be combined with a battery assembly to form an electronic cigarette comprises a mouthpiece and a body detachable with the mouthpiece. The body includes an open end to discharge smoke into the mouthpiece, an oil storage cavity for storing tobacco oil is defined inside the body, a receiving groove is defined at the open end, an filler hole connected to the oil storage cavity is defined on a bottom wall of the receiving groove, and an elastomeric seal for sealing up the filler hole is received in the receiving groove. By implementing the filler hole, it is easier to add the tobacco oil, and by implementing the elastomeric seal, the tobacco oil can be avoided leaking out. Further, the atomization assembly is provided with simple structure, compact connection and easy assembly.

A pair of first electrodes is connected to the outer pattern part and a pair of second electrodes is connected to the inner pattern part and spaced apart from the pair of first electrodes, and the pair of second electrodes are located inside the outer pattern part.

The present invention is directed to high temperature energy storage arrangements that utilize electrical heating elements for charging a carbon-based heat retaining core. A high temperature electrically isolating support element is used to support a resistive heating element. The components are designed for extended life in a high temperature thermal core with frequent thermal cycling. The heat retaining core is of graphite or carbon based material that is electrically conductive. The electrically isolating support element reduces leakage current losses while providing high mechanical strength and effective heat transfer from the resistive heating element to the heat retaining core. The contact surface of the electrically isolating support element and the resistive heating element is limited while still providing effective mechanical support. The support element and heating element engage in a manner to locate and position the support element on the heating element.

A unitary garment heating device that integrates with a garment to provide uniform heat throughout the garment. The device includes a plurality of nodes that position on various areas of the garment to distribute the heat. The nodes are fabricated from a conductive metallic yarn. A continuous conduit having no junctions carries current for generating heat, and connects the nodes to form a unitary heating device. The conduit is fabricated from the same material as the nodes, thereby forming a unitary device. The lack of junctions on the conduit helps eliminate problems such as shorts, and moisture exposure form rain or sweat. The conduit runs in a series circuitry to minimize shorts and arcing. The conduit is covered with a laminate and urethane to inhibit contact with moisture. A communication apparatus, such as a smart phone, monitors and regulates the temperature. A power supply and microprocessor are also attached.

An aerosol-generating article may comprise a liquid storage portion containing a liquid aerosol-forming substrate, and a hydrochromic material provided on the liquid storage portion. The hydrochromic material has a first colour when in the presence of or when in contact with the liquid aerosol-forming substrate and a second colour when in the absence of or when not in contact with the liquid aerosol-forming substrate. An aerosol-generating system may comprise the aerosol-generating article, an aerosol-generating element, and an aerosol-generating device. An aerosol-generating device may comprise an electrical power supply, an electronic photosensor, and a controller configured to control a supply of electrical power from the electrical power supply based on a value of an optical property sensed with the electronic photosensor.

A flavored vapor generator (100, 200, 300, 400) used for an electronic smoking apparatus (10) comprises a housing; a liquid retention material (155, 255) which is filled, soaked or immersed with a flavored liquid and received inside the housing; an electric heater (150, 350, 450) for heating the liquid retention material (155, 255) to generate flavored vapor; and a sensor (156, 356, 456) for monitoring soaking or wetness conditions of the liquid retention material (155, 255) and providing signals for determining whether the flavored liquid in the liquid retention material (155, 255) is exhausted or almost exhausted.
