Abstract: An atomizer includes an elastic member. The elastic member includes an atomization core, a support base, an air regulation ring, and a seal ring. The support base includes an e-liquid inlet. The atomization core is disposed on the support base to atomize e-liquid. The seal ring is disposed in the support base and below the atomization core. The air regulation ring is disposed around the support base; when the air regulation ring is pulled down, the atomization core is ejected from the top of the atomizer for replacement, and the e-liquid inlet of the support base is automatically sealed by the seal ring so that no e-liquid leaks out of the atomizer.

Abstract: A glass atomizer includes a member for e-liquid injection and vapor discharge. The member for e-liquid injection and vapor discharge includes an outer glass tube and an inner glass tube disposed in the outer glass tube. The outer glass tube includes an air inlet. The inner glass tube includes a top end, and the outer edge of the top end includes a plurality of grooves. The top end is integrated with the inner wall of the outer glass tube.

Abstract: A hookah, including a high-frequency heating component and a filter assembly. The high-frequency heating component includes a conductive cup and a magnetic induction coil. The conductive cup is disposed in the magnetic induction coil and configured to accommodate a tobacco material. When in use, an alternating current is introduced to the magnetic induction coil, and a magnetic induction effect is generated, so that the conductive cup is heated and the heat is transferred to the tobacco material whereby the tobacco material is heated and smoke is produced. The smoke is filtered in the filter assembly and inhaled by a user.

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 tobacco roaster includes an electromagnetic induction roasting module. The electromagnetic induction roasting module comprises a cup, a metal insert, and a magnetic induction coil. The metal insert is disposed in the cup. In a power-on state of the magnetic induction coil, the metal insert produces heat to heat a tobacco material in the cup to produce smoke.

Abstract: An electronic cigarette includes a squeezing module. The squeezing module includes a first seal ring, a movable part, a spring, and a fixed base. The movable part is disposed in the fixed base and the outer wall of the movable part is slidable along the inner wall of the fixed base. The first seal ring is disposed between the outer wall of the movable part and the inner wall of the fixed base. The spring is disposed in the fixed base and below the movable part to reset the movable part when a pressure force on the movable part is withdrawn.

Abstract: An electronic cigarette including an atomization assembly and a battery assembly. The atomization assembly is disposed on the battery assembly. The battery assembly includes an air column and a plate including a pneumatic switch. When in use, airflow passes through the air column to drive the plate including the pneumatic switch to work. The air column and the plate are disposed on the top end of the battery assembly, and the air column is staggered with the plate thus preventing an e-liquid from flowing onto the plate.

Abstract: A heating handle includes a housing and a magnetic induction coil. The housing is L-shaped and includes a through hole, and the magnetic induction coil is disposed in the through hole.

Abstract: A hookah, including a pipe body, a handle, a high-frequency heater, a smoke filter, and a cigarette holder. The high-frequency heater is disposed in the pipe body. The smoke filter and the cigarette holder are disposed in the handle.

Abstract: A smoke generation and filtration device includes: a heating component, configured to heat tobacco material to generate smoke; and a smoke filtration component including water, configured to filter toxins out from the generated smoke passing through the water. The smoke filtration component includes a first end and a second end opposite to the first end; and the heating component is detachably connected to the first end, and the second end includes a contact part through which a user inhales the smoke.

Abstract: The atomizer includes a housing, and an atomization assembly disposed in the housing. When in use, the atomizer is detachably connected to a high-frequency heater. The atomization assembly includes an atomizing core, a heating element, and a sleeve. The sleeve is connected to and enclosed by the housing, and a cavity is formed between the sleeve and the housing. The atomizing core and the heating element are fixedly disposed in the sleeve. The atomizing core includes a first surface and a second surface which are disposed back to back. The sleeve includes a main body through which e-liquid flows from the cavity into the sleeve and accumulates around the first surface of the atomizing core. The heating element is surrounded by the second surface of the atomizing core.

Abstract: An atomization assembly, including a ceramic core and a stainless-steel tank. The ceramic core includes three or more heating elements connected in parallel. The ceramic core is disposed in the stainless-steel tank.

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 rechargeable battery includes a battery cell, a copper threaded ring, a joint, an insulation ring, a first ethylene-vinyl acetate (EVA) ring, a second EVA ring, a battery cartridge, a silicone ring, a pneumatic switch, a support, and a base cover. The copper threaded ring comprises a 510-type threaded interface and a surface provided with a cross-shaped indentation operating as an air inlet of the battery. The insulation ring is disposed in the copper threaded ring. The joint is a hollow structure and is disposed in the insulation ring. The copper threaded ring is disposed on a top end of the battery cartridge.
