insulating ring 75 is disposed between the first positive electrode
contact 73 and the first through hole 710 to electrically isolate
the first positive electrode contact 73 and the lower cover 71
while enhancing the sealing effect.
[0050] The second positive electrode contact 74 is sleeved in the
second insulating ring 76. The second positive electrode contact 74
and the second insulating ring 76 are inserted into one end of the
first through hole 710 away from the first positive electrode
contact 73, so that the first positive electrode contact 73 can be
inserted into and electrically contacts with the second positive
electrode contact 74.
[0051] Furthermore, in order to enhance the sealing property of the
reservoir chamber 51, a sealing ring 77 is disposed between the
liquid storage tube 50 and the lower cover 71.
[0052] Referring to FIG. 3 and FIG. 4 together, in the first
embodiment of the present disclosure, the atomizing head 90a
includes an atomizing head sleeve 91a having an atomizing chamber
910a therein, an atomizing assembly 93a, and a separator 95a. The
atomizing head sleeve 91a is generally a tubular body open at both
ends and includes a base 911a and a tube portion 912a provided on
the base 911a. A liquid inlet hole 913a in communication with the
liquid storage tube 50 is defined on the pipe wall of the tube
portion 912a, a vent 914a in communication with the atomizing
chamber 910a is defined at the top of the tube portion 912a.
[0053] The atomizing assembly 93a is received in the atomizing
chamber 910a. the atomizing assembly 93a includes a liquid guiding
member 930a, a heating element 932a, and a fixing seat 934. The
liquid guiding member 930a is provided with a receiving hole 9301.
The heating element 932a is housed in the receiving hole 9301. The
fixing base 934 is sleeved outside of the liquid guiding member
930a and is provided with a liquid guiding groove 9341 in
communication with the liquid inlet hole 913a. In one embodiment,
the receiving hole 9301 is perpendicular to the atomizing head
sleeve 91a.
[0054] In one embodiment, the atomizing assembly 93a is received in
the atomizing chamber 910a in a direction perpendicular to the axis
of the atomizing head sleeve 91a. The liquid guiding member 930a is
a substantially semi-cylindrical body. The receiving hole 9301 is
disposed along the axial direction of the liquid guiding member
930a and extends through the opposite ends of the liquid guiding
member 930a. The axial direction of the receiving hole 9301 is
perpendicular to the axial direction of the atomizing head sleeve
91a. The heating element 932a is a hollow cylindrical spiral
heating wire open at both ends and is housed in the receiving hole
9301 in the axial direction of the receiving hole 9301. It can be
understood that, in other embodiments, the heating element 932a may
also be a hollow heating pipe open at both ends. The fixing base
934 is a hollow semi-cylindrical shape engaging with the liquid
guiding member 930a and is sleeved outside of the liquid guiding
member 930a. The liquid guiding groove 9341 in communication with
the liquid inlet hole 913a is respectively defined at both ends of
the fixing seat 934 in the radial direction thereof.
[0055] The separator 95a is connected between the atomizing
assembly 93a and the air outlet pipe 37, and isolates the vent 914a
to form an air inlet 915a and an air outlet 916a on both sides of
the atomizing assembly 93a. The separator 95a is perpendicular to
the axis of the heating element 932a, whereby the air inlet 915a is
in communication with the opening of one end of the heating element
932a, the air outlet 916a is in communication with the opening of
the opposite end of the heating element 932a. The gap between the
vent pipe 35 and the air outlet pipe 37 forms an intake passage 917
in communication with the intake hole 310 and the air inlet 915a.
The air outlet pipe 37 defines an outlet passage 918 in
communication with the air outlet 916a and the mouthpiece connector
10. Thereby, the outside air enters the intake passage 917 from the
passage between the adjustment groove 330 and the intake hole 310,
to the air inlet 915a, and to the inner cavity of the heating
element 932a via the opening of one end of the heating element
932a. Then, the outside air is sufficiently mixed with the smoke,
and sequentially flows out from the opposite end of the heating
element 932a, the air outlet 916a, the outlet passage 918a, and the
mouthpiece connector 10 for the user to inhale. Since the outside
air flows through the entire inner cavity of the Heating element
932a, on the one hand, the outside air can take all the smoke out
to prevent the smoke from being liquefied and formed into an
effusion after the atomizer 100 is stopped. On the other hand, the
temperature distribution of the inner cavity of the heating element
932a is uniform, without local overheating, and further, the
leakage of the smoke liquid adsorbed by the liquid guiding member
930a due to the sudden drop in temperature and the sudden drop in
pressure is prevented from forming effusions.
[0056] Specifically, the separator 95a has a substantial plate
shape. An edge of the separator 95a facing one end of the atomizing
assembly 93 is recessed inward to form a latching groove 950a
engaging with the outer circumference of the fixing seat 934. In
the embodiment, the latching groove 950a has a semi-circular
arcuate shape. The separator 95a is engaged with the fixing seat
934 through the latching groove 950a in a direction perpendicular
to the axis of the liquid guiding member 930a. In this embodiment,
one end of the separator 95a is vertically clamped on the fixing
seat 934 through the latching groove 950a. The vent 914a having a
circular cross-section shape is isolated by the separator 95a to
form an air inlet 915a and an air outlet 916a. The air inlet 915a
and the air outlet 916a has a semicircular cross-section,
respectively. The cross section of the air outlet pipe 37 is a
semicircular shape matching the air outlet 916a, and one end of the
separator 95a with respect to the fixing seat 934 abuts against the
air outlet pipe 37. The air inlet 915a and the air outlet 916a are
in communication with each other through the inner cavity of the
heating element 932a, so that the outside airflow passes from the
intake hole 310, the intake passage 917, and the air inlet 915a
successively, to the inner cavity of the heating element 932a in
the lateral direction, and then flowing out through the air outlet
916a, the outlet passage 918 and the mouthpiece connector 10
successively.
[0057] Furthermore, the atomizing head 90a further includes an
atomizing head positive electrode contact 96 and an atomizing head
insulating ring 97. The atomizing head positive electrode contact
96 is disposed at the bottom of the base 911a and electrically
connected to the first positive electrode contact 73 through the
second positive electrode contact 74. The atomizing head insulating
ring 97 is disposed between the atomizing head positive electrode
contact 96 and the base 911a and electrically insulates both.
[0058] Referring to FIG. 5 and FIG. 6, in the second embodiment of
the present disclosure, the atomizing head 90b includes an
atomizing head sleeve 91b having an atomizing chamber 910b (shown
in FIG. 7) therein, an atomizing assembly 93b, and a separator 95.
The atomizing head sleeve 91b is generally a tubular body open at
both ends. The atomizing head sleeve 91b includes a base 911b and a
tube portion 912b provided on the base 911b. The corresponding
positions of the bottom edge of the tube portion 912b and the top
edge of the base 911b are recessed to form an arc-shaped notch, and
when the two are assembled integrally, the corresponding notches
collectively define a liquid inlet hole 913b in communication with
the liquid storage tube 50. A vent 914b in communication with the
atomizing chamber 910b is defined at the top of the tube portion
912b.
[0059] The atomizing assembly 93b is received in the atomizing
chamber 910, especially the atomizing assembly 93b is received in
the atomizing chamber 910b in a direction perpendicular to the
axial direction of the atomizing head sleeve 91b. The atomizing
assembly 93b includes a liquid guiding member 930b and a heating
element 932b. The liquid guiding member 930b has a cylindrical rod
shape and is inserted into the liquid inlet hole 913b in the axial
direction of the liquid inlet hole 913b. The heating element 932b
is a hollow heat generating tube open at both ends, a liquid inlet
groove is defined on the circumferential side of the heat
generating tube. It can be understood that, in other embodiments,
the heating element 932b can also be a hollow cylindrical spiral
heating open at both ends. The heating element 932b is sleeved on
the outer circumference of the liquid guiding member 930b along the
axial direction of the liquid guiding member 930b.
[0060] Referring to FIG. 7 and FIG. 8, the separator 95b has a
substantially long plate shape, which is disposed on the top of the
atomizing assembly 93b in the direction parallel to the axis of the
liquid guiding member 930b. In the embodiment, one end of the
separator 95b abuts against the top of the heating element 932b in
the axial direction of the liquid guiding member 930b, the opposite
end of the separator 95b is clamped in the vent 914b and isolates
the vent 914b to form the air inlet 915b and the air outlet 916b.
The air inlet 915b and the air outlet 916b are in communication
with each other through the bottom of the outer periphery of the
heating element 932b. The external airflow passes from the air
inlet 915b, to the bottom along the top of one side of the outer
circumference of the heating element 932b, and to the top along the
bottom of the other side of the outer periphery of the heating
element 932b, then flows out through the air outlet 916b. Thus, the
external airflow can flow through the entire heating element 932b
in the atomizing chamber 910b, thereby reducing the temperature
difference and avoiding effusion problems. Further, the outside air
can bring all the smoke out, to prevent the smoke from returning to
the liquid state and forming effusions after the atomizer 100 is
stopped.
[0061] Referring to FIGS. 9-11, in the third embodiment of the
present disclosure, the atomizing head 90c includes an atomizing
head sleeve 91c having an atomizing chamber 910c therein, an
atomizing assembly 93c, and a separator 95c. The atomizing head
sleeve 91c is generally tubular open at two ends. The atomizing
head sleeve 91c includes a top cover 911c and a tube portion 912c
connected to the lower portion of the top cover 911c. The top cover
911c has a tubular shape open at two ends, the opposite sides of
the inner wall surface are provided with a receiving groove 919c in
the direction of the axis of the inner wall. A vent 914c is defined
at the top of the top cover 911c. The top edge of the tube portion
912c and the corresponding position of the receiving groove 919c on
the inner wall of the top cover 911c are recessed to form a notch
920c, when the receiving groove 919c and the notch 920c are
integrally assembled, the receiving groove 919c is aligned with and
in communication with the corresponding notch 920c.
[0062] The atomizing assembly 93c is housed in the atomizing
chamber 910c in the axial direction parallel to the atomizing head
sleeve 91c and includes a liquid guiding member 930c and a Heating
element 932c. The liquid guiding member 930c has a hollow
cylindrical rod shape open at two ends. A liquid inlet hole 913c in
communication with the liquid guiding member 930c is defined on the
circumferential side of the tube portion 912c. In the embodiment,
the heating element 932c is a hollow cylindrical spiral heating
wire that is open at two ends. The heating element 932c is axially
sleeved in the liquid guiding member 930c along the liquid guiding
member 930c and abuts against the inner wall of the liquid guiding
member 930c. It can be understood that, in other embodiments, the
heating element 932c can also be a hollow cylindrical tube with an
opening at two ends.
[0063] The separator 95c is substantially a T-shaped plate. The
wider end of the separator 95c is supported on the tube portion
912c, and is inserted into the notch 920c and the receiving groove
919c.
[0064] The narrower end of the separator 95c is inserted into the
heating element parallelly along the axial direction of the liquid
guiding member 930c, to isolate the vent 914c to form the air inlet
915c and the air outlet 916c. The air inlet 915c and the air outlet
916c communicate with each other through the bottom of the inner
cavity of the heating element 932c. The external airflow flows in
through the air inlet 915c, to the bottom along the top of the
inner side of the heating element 932c, and to the top along the
bottom of the other side of the heating element 932c and flows out
through the air outlet 916c. Thus, the external airflow can pass
through the entire heating element 932c in the atomizing chamber
910c, thereby reducing the temperature difference and solving the
problem of fluid accumulation. On the other hand, the outside air
can bring all the smoke out, to prevent the smoke from returning to
the liquid state and forming effusions after the atomizer 100 is
stopped.
[0065] The present disclosure also provides an electronic cigarette
(not shown) having any one of the above atomizer 100.
[0066] In the present disclosure, the vents 914a/b/c of the
atomizing heads 90a/b/c are separated by the separators 95a/b/c to
form the air inlet 915a/b/c and the air outlet 916a/b/c. The air
inlet 915a/b/c and the air outlet 916a/b/c are in communication
with each other through the inside chamber, the inner bottom or the
outer bottom of the heating elements 932a/b/c in the atomizing
assemblies 93a/b/c. Thereby, when the outside air enters, the
external airflow can across through or flow through the entire
heating element 932a/b/c in the atomizing chamber 910c, thereby
reducing the temperature difference and avoiding effusion problems.
Further, the outside air can bring all the smoke out, to prevent
the smoke from returning to the liquid state and forming effusions
after the atomizer 100 is stopped.
[0067] The above-mentioned embodiments merely represent several
implementations of the present application, and the descriptions
thereof are more specific and detailed, but they shall not be
understood as a limitation on the scope of the present application.
It should be noted that, for those of ordinary skill in the art,
variations and improvements may still be made without departing
from the concept of the present application, and all of which shall
fall into the protection scope of the present application.
Therefore, the scope of protection of the present application shall
be subject to the appended claims.
