Atomizing device and electronic cigarette having same

Abstract

An atomizing device of an electronic cigarette includes an atomizing sleeve, an air pipe located in the atomizing sleeve, a heating assembly arranged on the air pipe, a heating assembly fixing base fixing and supporting the heating assembly, a metallic sleeve supporting the heating assembly fixing base, and a sealing cover. The sealing cover and the heating assembly fixing base are respectively located at two opposite ends of the air pipe. The atomizing sleeve, the air pipe, the sealing cover, the heating assembly fixing base, and the metallic sleeve cooperatively define a sealed tobacco solution reserving space without a reservoir cotton received therein. An electronic cigarette using the atomizing device is also provided.

What is claimed is: 
     
         1 . An atomizing device of an electronic cigarette, comprising:
 an atomizing sleeve;   an air pipe located inside the atomizing sleeve;   a heating assembly arranged on the air pipe;   a heating assembly fixing base fixing and supporting the heating assembly;   a metallic sleeve supporting the heating assembly fixing base; and   a sealing cover, wherein the sealing cover and the heating assembly fixing base are respectively located at two opposite ends of the air pipe, and the atomizing sleeve, the air pipe, the sealing cover, the heating assembly fixing base, and the metallic sleeve cooperatively define a sealed tobacco solution reserving space without a reservoir cotton received therein.   
     
     
         2 . The atomizing device of  claim 1 , further comprising a tobacco solution obstructing ring arranged on the air pipe and above the heating assembly. 
     
     
         3 . The atomizing device of  claim 2 , wherein the tobacco solution obstructing ring comprises a first ring and a second ring in communication with the first ring, a diameter of the second ring is greater than that of the first ring, and the second ring is in contact with the heating assembly. 
     
     
         4 . The atomizing device of  claim 3 , wherein an outer wall of the second ring has a cutout surface facing toward the atomizing sleeve. 
     
     
         5 . The atomizing device of  claim 2 , wherein the tobacco solution obstructing ring is made of a flexible material. 
     
     
         6 . The atomizing device of  claim 1 , wherein the atomizing sleeve has a tobacco solution obstructing structure integrally formed thereon, the tobacco solution obstructing structure has a through hole surrounding the air pipe, and an end of the tobacco solution obstructing structure is in contact with the heating assembly. 
     
     
         7 . The atomizing device of  claim 6 , wherein an inner wall of the tobacco solution obstructing structure has a cutout surface facing toward the air pipe. 
     
     
         8 . The atomizing device of  claim 1 , wherein the sealing cover is made of a flexible material, the sealing cover has a tobacco solution filling hole, and the tobacco solution filling hole is a blind hole. 
     
     
         9 . The atomizing device of  claim 1 , wherein the heating assembly comprises a glass fiber core and a heating coil winding around the glass fiber core; the heating assembly fixing base comprises a central through hole, a first sidewall through hole and a second sidewall through hole, two ends of the heating coil respectively extend through the first sidewall through hole and the second sidewall through hole, and respectively bend at an outer wall of the heating assembly fixing base and an inner wall of the central through hole. 
     
     
         10 . The atomizing device of  claim 1 , further comprising a nozzle arranged on the sealing cover and in communication with the air pipe. 
     
     
         11 . An electronic cigarette comprising an atomizing device of  claim 1 , and a battery assembly connected to the atomizing device.
