DETAILED DESCRIPTION

Embodiments of the present disclosure will now be described in detail below and with references to the drawings.
Referring to FIGS. 1-2, an atomizer 11 for an electronic cigarette includes a housing 10, a mouthpiece cover 20 at one end of the housing 10. The mouthpiece cover 20 defines an air outlet 201. Then referring to FIGS. 3 and 5, an atomizing part 60 for atomizing tobacco solution and a solution cup 31 are disposed in the housing 10. The solution cup 31 defines a solution reservoir 30 for reserving the tobacco solution. The atomizing part 60 includes an atomizing cup 62 with an atomizing cavity 621, and an atomizing unit 61 arranged in the atomizing cavity 621. The housing 10 defines an air inlet 202, an aerosol outlet 102, and an air passage 101 communicating with the air inlet 202 and the aerosol outlet 102. The mouthpiece cover 20 is arranged at one end of the housing 10 with the aerosol outlet 102. The air outlet 201 communicates with the aerosol outlet 102. A first solution conducting component 40 is arranged between the solution reservoir 30 and the atomizing part 60. The atomizing part 60 is configured for conducting the tobacco solution from the solution reservoir 30 to the atomizing cup 62, and is capable of preventing the tobacco solution from leaking out. In the present embodiment, the first solution conducting component 40 is a porous ceramic body. The first solution conducting component 40 absorbs the tobacco solution stored in the solution reservoir 30 by capillary action, holds the tobacco solution, and prevents the tobacco solution from leaking out. After the tobacco solution permeates the first solution conducting component 40, the tobacco solution is stored in the first solution conducting component 40, and is then provided to the atomizing unit 61 for atomization. In the present embodiment, the solution cup 31 is substantially cylindrical, the air passage 101 is a gap formed between the solution cup 31 and the housing 10, and the first solution conducting component 40 is plate shaped.
Because the first solution conducting component 40 is arranged between the solution reservoir 30 and the atomizing part 60, and the first solution conducting component 40 is made of porous ceramic, the first solution conducting component 40 can convey the tobacco solution from the solution reservoir 30 to the atomizing cup 62 for atomization by the capillary action due to porous characteristics. The first solution conducting component 40 can prevent the tobacco solution in the solution reservoir 30 from leaking out. Thus, the first solution conducting component 40 conducts the tobacco solution well, and has the effect of preventing the tobacco solution from leaking out. Furthermore, the present atomizer 11 has the advantage of simple assembly.
Referring to FIG. 3, a connecting tube 50 for fixing the solution cup 31 is fixed in the housing 10. The atomizing part 60 is received in the connecting tube 50. Also referring to FIG. 4, the solution reservoir 30 includes an opening end 301. The first solution conducting component 40 is disposed in the opening end 301, and abuts against one end of the atomizing cup 62 with the atomizing cavity.
A first electrode 70 and a second electrode 90, which are configured for connecting to an external power source 12 (referring to FIG. 9), are further arranged in the housing 10. An insulator 80 is disposed between the first electrode 70 and the second electrode 80, and the insulator 80 makes the first electrode 70 insulated from the second electrode 80. In the present embodiment, the insulator 80 is an insulated ring nesting the second electrode 90, and is made of silica gel. The insulator 80 makes the first electrode 70 not in contact with the second electrode 90. Referring to FIG. 5, the atomizing unit 61 includes a heating wire 612 and a second solution conducting component 611. One end of the heating wire 612 is electrically connected to the first electrode 70 of the atomizer 11, and the other end of the heating wire 612 is electrically connected to the second electrode 90 of the atomizer 11. The second solution conducting component 611 is in contact with the first solution conducting component 40 so that the tobacco solution reserved in the first solution conducting component 40 is conveyed to the heating wire 612 for atomization. In the present embodiment, the first electrode 70 is electrically connected to a negative electrode of the power source 12, and the second electrode 90 is electrically connected to a positive electrode of the power source 12. The first electrode 70 includes screws for connecting with the external power source 12, and the screws are internal screws 701. The air inlet 202 is formed in the second electrode 90.
In the present embodiment, the second solution conducting component 611 is made of glass fiber, the housing 10 is made of a partially transparent housing, and the solution cup 31 is made of transparent material. Because the quantity of the tobacco solution in the solution reservoir 30 can be clearly seen through a transparent part of the housing 10, it is prevented that the heating wire 612 keeps heating after the tobacco solution is used up. In other embodiments, the second solution conducting component 611 may also be made of porous ceramic, and the entire solution cup 31 and the entire housing 10 may be made of transparent material.
Referring to FIGS. 6-8, the present embodiment mainly differentiates the first embodiment in that: an housing 10′ and the solution cup 31 of the first embodiment are integrally formed; a solution reservoir 30′ has an annular structure, defines an air passage 101′ centrally located within the solution reservoir 30′, and the air passage 101′ functions similarly as the air passage 101; a first solution conducting component 40′ includes a porous ceramic body 402 and a cotton cloth 404 formed on the bottom of the porous ceramic body 402. The cotton cloth can further prevent the tobacco solution from leaking out. In the present embodiment, screws for connecting the external power source 12 are external screws 702. The housing 10′ is an entirely transparent shell. The mouthpiece cover 20′ is made of semi-transparent material.
Referring to FIG. 9, an electronic cigarette includes an atomizer 11 according to the first embodiment, and a power source 12. The atomizer 11 and the power source 12 are connected via screw threads. The power source 12 is configured for supplying power for the atomizer 11. In other embodiments, the atomizer 11 can also be replaced by the atomizer 10′ as described in the second embodiment.
It is understood that the above-described embodiments are intended to illustrate rather than limit the disclosure. Variations may be made to the embodiments and methods without departing from the spirit of the disclosure. Accordingly, it is appropriate that the appended claims be construed broadly and in a manner consistent with the scope of the disclosure.
