liquid passage. The liquid blocking element is configured for
absorbing and storing the tobacco liquid flowed from the liquid
passage. However, in the atomizer, the tobacco liquid may leak from
the liquid blocking element.
[0003] What is needed, therefore, is an atomizing head, an atomizer
and an electronic cigarette using same, which can overcome the
above shortcomings.

FIRS EMBODIMENT
[0032] Referring to FIGS. 1-2, an atomizing head 100 for an
electronic cigarette is shown. The atomizing head 100 includes a
holder 110, an air inlet 151, an air outlet 141, a piercing element
120, a first electrode 160, a second electrode 150, a buffer
chamber 111, an atomizing cavity 1232, and an atomizing component
170. The piercing element 120 is configured for pricking a liquid
supply. The atomizing component 170 is configured (i.e., structured
and arranged) for absorbing heating tobacco liquid in the buffer
chamber 111 and heating the tobacco liquid. Both of the air outlet
141 and the air inlet 151 are in communication with the atomizing
cavity 1232. The air inlet 151 is defined in the second electrode
150. The first electrode 160 and the second electrode 150 are
configured for connecting to an external power supply. An
insulating body 180 is sandwiched between the first electrode 160
and the second electrode 150. The piercing element 120 includes a
liquid inlet 121, and the liquid inlet 121 communicates with the
buffer chamber 111.
[0033] After the piercing element 120 pierces the liquid supply,
the tobacco liquid in the liquid supply first flows into the buffer
chamber 111 via the liquid inlet 121, and is then absorbed by the
atomizing component 170. Accordingly, liquid leakage of the
atomizing head is greatly improved.
[0034] Referring to FIGS. 3-4, the piercing element 120 includes a
connecting part 123 and a piercing part 122. The piercing part 122

[0037] Referring to FIGS. 2 and 5, the holder 110 is further
provided with a fixing cover 140, and the air outlet 141 is defined
in the fixing cover 140. The fixing cover 140 further defines an
assembling hole 143 and a slot 142. The slot 142 is configured for
giving way to the liquid passage 1233, so that the tobacco liquid
can flow into the buffer chamber 111 via the liquid passage
smoothly. The assembling hole 143 allows the piercing element 122
to pass through. The atomizing head 100 further includes a liquid
blocking gasket 130. The liquid blocking gasket 130 is laminated on
the fixing cover 140. The liquid blocking gasket 130 nests the
piercing part 122, and is configured for sealing the liquid supply
after the liquid supply is pierced. In the present embodiment, the

atomizing head 100 further includes a liquid blocking element 190
in the atomizing cavity 1232. The liquid blocking element 190
prevents tobacco liquid dropped from the atomizing component 170
from flowing out of the air inlet 151. In the present embodiment,
the liquid blocking element 190 may be made of glass fiber material
or ceramic material.
[0040] Referring to FIG. 6, as an alternative embodiment, a liquid
conducing body 12331 may be arranged in the liquid passage 1233.
One end of the liquid conducting body 12331 is positioned in the
liquid inlet 121, and an opposite end of the liquid conducting body
12331 is positioned in the buffer chamber 111. The liquid
conducting body 12331 is configured for conveying the tobacco
