A vaporizer device and associated methodology for providing accurate sampling through substantially efficient, complete and uniform single pass vaporization of a liquid sample by avoiding liquid pre-vaporization and downtime attributable to system damage from incomplete vaporization, particularly in the distribution, transportation, and custody transfer of natural gas. The vaporizer device includes at least one input port for receiving a liquid sample, a channel for directing the liquid to a vaporizer core and a heating assembly within the vaporizer core configured to flash vaporize the liquid sample. The vaporized sample can then be passed to an outlet for sample analysis.

An automatically resettable smoking paraphernalia includes the following components: an outer upper shell, a smoking cup provided inside the outer upper shell, a pushing key, and a spring, etc., wherein the smoking cup, the spring, the outer upper shell can be detached and replaced as a whole, the smoking cup can stick out of the outer upper shell by a distance to extract and unload the cigarette, and then automatically reset. Besides, the smoking cup is hidden inside the upper outer shell, so as to prevent the exposed smoking cup with an excessively high temperature from burning users, meanwhile avoiding a risk of losing the smoking cup.

An electrical connection interface (100) of a device for electrically heating a flow of air flowing within a ventilation, heating and/or air conditioning system of a motor vehicle comprises, in a panel (102), at least one notch that is dimensioned for receiving a connection terminal (126) mounted at the end of an electrode of a heating element of the electric heating device. The electrical connection interface comprises at least one device for limiting the shear (101) of the connection terminal which extends proud from the panel (102) adjacent to the notch.

A treatment instrument including a heat transmitter that includes a treating surface and an installation surface, a substrate attached to the installation surface, and a heat generator formed on a surface of the substrate. The substrate surface and heat generator together form an uneven surface. First and second adhesion layers formed of a material having thermal conductivity and electrical insulation are provided between the installation surface and the substrate. The first adhesion layer is in close contact with the installation surface, and the second adhesion layer is in close contact with the heat generator and the substrate surface. The second adhesion layer is inserted into a recess in the uneven surface formed by the heat generator on substrate surface so as to increase the contact area between the second adhesion layer and the uneven surface.
