Abstract: A high-frequency heating device, includes: a housing, a thermal insulation cup, and a magnetic induction coil. The housing includes a cavity and the magnetic induction coil is disposed in the cavity. The thermal insulation cup is nested in the magnetic induction coil.

Abstract: A shisha device comprises a cooling element (13) disposed along an airflow channel to cool an aerosol. The cooling element unit utilizes active cooling and may additionally utilize passive cooling. The cooling element may comprise a conduit (21) comprising a thermally conductive material. The cooling element may be integrally formed with an accelerating element (14) disposed along the airflow channel. Cooling may occur before or during acceleration of the aerosol by the accelerating element. The cooling may contribute to the condensation in the aerosol.

Abstract: An apparatus (100) for crimping a band of material and a method of crimping and shaping a band of material is disclosed. The apparatus (100) comprising a crimping portion (1) comprising a first crimping roller (2) defining a first rotational axis and a second crimping roller (3) defining a second rotational axis, wherein the first and second crimping rollers are configured to allow a band of material to pass therebetween and towards an adjacent apparatus; and an adjustment portion (20) configured to adjust the position of at least one of the first and second rotational axes relative to the position of the adjacent apparatus to thereby adjust the tension in the band of material between the crimping portion and the adjacent apparatus.

Abstract: A tobacco feeding device incudes a glass tube, a push rod, and a piston. The piston is movable along the inner wall of the glass tube. The push rod includes an air passage. The glass tube includes a feeding inlet. When the piston moves along the inner wall of the glass tube, a gap between the feeding inlet and the piston is exposed and a tobacco material is added to the tobacco feeding device. When in use, smoke produced by the tobacco material circulates in the air passage.

Abstract: An atomization assembly, including an e-liquid tank, a connector, a seal ring, a spring, a first fixed ring, an atomizer, a silicone seal, a silicone plug, and a base. The spring is disposed in the seal ring. The seal ring is disposed around the connector. The connector, the seal ring, and the spring are disposed in the first fixed ring. The silicone seal is disposed on the base. The base is disposed on the e-liquid tank. Two ends of the first fixed ring are connected to the base and the e-liquid tank, respectively. The silicone plug is fixed on the base. The atomizer is fixed on the first fixed ring.

Abstract: A system for smoking a product includes a vase for containing a liquid. The vase has a closed bottom, and a side wall extending from the closed bottom and an open top that is unobstructed. The system further includes a bottle for inserting into and removing from the vase. The bottle has an open bottom, an open top, a flange circumscribing the bottle adjacent the open top, and a conical opening in the open top that is unobstructed. In addition, the system includes a grommet mounted to the open bottom of the bottle such that the open bottom is substantially unobstructed. Lastly, the system includes a bowl with a conical exterior that is complementary in shape to the conical opening in the bottle. The bowl can form a conical, glass-to-glass seal with the bottle.

Abstract: The present disclosure has provided an automatic multichannel apparatus for assessing hot coal fallout propensity of burning cigarettes and an assessing method thereof. The apparatus comprises a multichannel rotary plate unit, an automatic supplying unit for cigarette samples, an automatic ignition and burning line detection unit for cigarette samples, a cigarette holding and force applying unit, an automatic hot coal fallout detection and removal unit, a smoke collecting unit during suction, a suction unit, a gas exhaust unit arranged in a main frame, and an electric circuit and air path control unit for controlling actions and processes of the above units. The apparatus operates based on certain steps and performs automatic ignition and burning line detection on cigarette samples inserted into a rotary plate in sequence.

Abstract: An electronic cigarette including an atomization assembly and a battery assembly. The atomization assembly is disposed on the battery assembly. The atomization assembly includes a base seat. The battery assembly includes a copper threaded ring and a control panel. The base seat is in threaded connection to the copper threaded ring so that the atomization assembly is integrated with the battery assembly. The control panel includes a pneumatic switch disposed in an air passage of the electronic cigarette. When in use, the air passes through the air passage to activate the pneumatic switch to work.

Abstract: A handheld hookah includes a gas valve assembly including a gas valve and a central shaft. The gas valve includes a first air duct and a second air duct. The central shaft includes a third air duct and a fourth air duct. The first air duct and the second air duct each includes a first end and a second end. When in use, the handheld hookah is placed vertically and added with water, a liquid level of the water is lower than that of the first end of the second air duct, but higher than that of the second end of the first air duct. The first end of the first air duct is connected to the third air duct so that the smoke goes into the first air duct from the third air duct. The second end of the first air duct is disposed in the water.
