- An exemplary atomizer includes a housing and an atomizing core arranged in the housing. The housing defines a liquid chamber configured for accommodating tobacco liquid. The atomizing core is configured for atomizing the tobacco liquid to form aerosol. The atomizing core includes a hollow tubular heating body and a liquid conducting element wrapping around the heating body. The liquid conducting element is configured guiding the tobacco liquid in the liquid chamber to the heating body for atomization. The heating body defines a passage for aerosol. The heating body is made of metal. The heating body includes a sidewall defining a plurality of openings.

- Referring to
FIGS. 1-2 , anatomizer 10 for an electronic cigarette is shown. Theatomizer 10 includes ahousing 101, and an atomizingcore 103 in thehousing 101. Thehousing 101 defines aliquid chamber 102 for containing tobacco liquid. The atomizingcore 103 is configured (i.e., structured and arranged) for atomizing the tobacco liquid to form aerosol. Anend cover 108 is provided at an end of thehousing 101, and theend cover 108 includes amouthpiece 109 for inhaling aerosol. Theend cover 108 is detachably connected to thehousing 101, and is configured for sealing a top opening of theliquid chamber 102. Tobacco liquid can be filled into theliquid chamber 102 when screwing off theend cover 108. Anelectrical connecting assembly 106 is detachably provided at the other end of thehousing 101. Theelectrical connecting assembly 106 includes a plurality ofscrew threads 107 for connecting with an external power supply. The atomizingcore 103 acquires power via theelectrical connecting assembly 106. The atomizingcore 103 is detachably arranged on theelectrical connecting assembly 106, and is in theliquid chamber 102. When theelectrical connecting assembly 106 is detached, the atomizingcore 103 can be replaced easily. - The atomizing
core 103 includes a hollowtubular heating body 20 and a liquid conductingelement 105 wrapping around theheating body 20. The liquid conductingelement 105 is configured for guiding the tobacco liquid in theliquid chamber 102 to theheating body 20 for atomization. Theheating body 20 defines apassage 202 allowing the aerosol to flow out. Theheating body 20 is made of metallic material, and defines a plurality of openings evenly arranged in a sidewall. - In the present embodiment, the
heating body 20 is made of metallic material with a certain electrical resistivity and a relatively high strength. Quite usefully, theheating body 20 is made of 316 stainless steel, 304 stainless steel, nickel chromium alloy, or iron-chromium-aluminum alloy. The liquid conductingelement 105 may be made of cotton cloth, fiber cotton, or glass fiber or other porous material. Theheating body 20 is a metallic tube, and is in fully contact with the liquid conductingelement 105, so that the tobacco liquid in the liquid conductingelement 105 is heated uniformly. - An
air pipe 120 is further provided in theliquid chamber 102. A top end of theair pipe 120 is connected to themouthpiece 109, and a bottom end of theair pipe 120 is connected with the atomizingcore 103. Since theheating body 20 is arranged in the atomizingcore 103, themouthpiece 109 is connected with thepassage 202 of theheating body 20 via theair pipe 120, so that the aerosol in thepassage 202 can be expelled via themouthpiece 109. - A
cover body 104 is provided nesting theair pipe 120. A top end of thecover body 104 is connected with theend cover 108, and thecover body 104 is movable together with theend cover 108. When theend cover 108 is detached for filling tobacco liquid, a bottom end of thecover body 104 hermetically abuts against a bottom of theliquid chamber 102 driven by a spring. In this way, thecover body 104 nests theatomizing core 103, and the tobacco liquid in theliquid chamber 102 cannot flow into the atomizing core, thus avoiding liquid leakage during process of injecting tobacco liquid. After theend cover 108 is coupled to thehousing 101, theend cover 108 is capable of driving thecover body 104 to move upwards, so that the tobacco liquid in theliquid chamber 102 flows into theatomizing core 103. - Referring to
FIG. 2 , theatomizing core 103 further includes acylindrical shell 110. Theheating body 20 and theliquid conducting element 105 are received in theshell 110. Theshell 110 defines a plurality ofliquid inlets 111 in a sidewall. The tobacco liquid in theliquid chamber 102 can enter theliquid conducting element 105 via theliquid inlets 111 and be conveyed to theheating body 20. Theshell 110 includes anair inlet 112 and anair outlet 113 at two opposite ends. Theair inlet 112 and theair outlet 113 are in communication with each other via thepassage 202 in theheating body 20. Theshell 110 includes a plurality ofscrew threads 114 adjacent to theair outlet 113. Thescrew threads 114 are configured for connecting with theair pipe 120. Theshell 110 further includes a plurality ofscrew threads 115 adjacent to theair inlet 112. Thescrew threads 115 are configured for connecting with the electrical connectingassembly 106. - Referring to
FIG. 3 , aheating body 20 according to a first embodiment is shown. Theheating body 20 is formed by a metal foil.

Finally, twoelectrode parts electrode parts assembly 106, respectively. Theheating body 20 can heat uniformly. Further, a contact surface between theheating body 20 and theliquid conducting element 105 is large. Accordingly, an amount of aerosol generated by theheating body 20 is large. - Referring to
FIG. 4 , aheating body 30 according to a second embodiment is shown. Theheating body 30 is made of a metallic tube. The metallic tube defines apassage 302 for aerosol extending through the metallic tube. Two ends of the metallic tube are connected withelectrode parts openings 301. The strip shapedopenings 301 are not in communication with each other, and may be formed by etching. Quite usefully, theopenings 301 extend along a circumferential direction of the sidewall. Theopenings 301 in two adjacent rows are in a staggered fashion. It is to be understood that, in other embodiments, theopenings 301 may extend along an axial direction of the tube body. - Referring to
FIG. 5 , aheating body 40 according to a third embodiment is shown, in which electrode parts are omitted.
