Description
BACKGROUND OF THE PRESENT INVENTION
[0001] 1. Field of Invention
[0002] The present invention relates to a lighter, and more
particularly to a piezoelectric lighter with a pivot nozzle head,
wherein the nozzle head is adapted to turn with respect to a
lighter body so as to selectively adjust an ignition angle of the
nozzle head.
[0003] 2. Description of Related Arts
[0004] A lighter is a common tool that replaces matches for
igniting cigarettes and cigars. Generally, a conventional lighter,
such as a piezoelectric lighter, comprises a lighter casing having
a liquefied fuel storage, a gas nozzle extended to a ceiling of the
lighter casing and communicating with the liquefied fuel storage
for controlling a flow of gas, a piezoelectric unit disposed in the
lighter casing for generating sparks when the piezoelectric unit is
depressed, and a pusher button slidably mounted on the lighter
casing and arranged when the pusher button is depressed downwardly,
the piezoelectric unit is depressed while the gas is released from
the liquefied fuel storage to the gas nozzle and is ignited by the
sparks.
[0005] However, such piezoelectric lighter has a major drawback
that such piezoelectric lighter can provide a single ignition
angle. Since the gas nozzle is fixed to the lighter casing in an
upright manner, the gas can only upwardly ejected from the gas
nozzle to form the flame when the lighter is ignited. For example,
when the user wants to lighten up a candle, he or she may merely
put the lighter at a slanted position that the gas nozzle is
pointing at the top of the wick such that the flame can directly
lighten the wick. Since the gas is upwardly ejected from the gas
nozzle, the lighter cannot effectively lighten the candle when the
lighter is in such slanted position.
[0006] In order to solve the above problem, the lighter
manufacturer can make the piezoelectric lighter that the gas nozzle
is inclinedly supported at the lighter casing such that the gas
nozzle is adapted to directly pointing at the wick of the candle
while the lighter casing is at an upright manner. However, such
lighter is not practical use for lightening a cigarette. In
addition, most users would like to use a utility lighter having an
elongated gas nozzle tube to lighten up the candle. However, the
utility lighter is bulky that the user is unable to carry the
utility lighter in his or her pocket.
SUMMARY OF THE PRESENT INVENTION
[0007] A main object of the present invention is to provide a
piezoelectric lighter, which comprises a nozzle head adapted to
turn with respect to a lighter body so as to selectively adjust an
ignition angle of the nozzle head.
[0008] Another object of the present invention is to provide a
piezoelectric lighter, wherein the nozzle head is pivotally mounted
on the lighter body such that the user is able to pivotally turn
the nozzle head to select the gas ejecting either at an upright
manner or at an inclined manner from the nozzle head so as to
enhance the practical use of the piezoelectric lighter.
[0009] Another object of the present invention is to provide a
piezoelectric lighter, wherein the nozzle head comprises a nozzle
seat pivotally mounted to the lighter body and a gas emitting
nozzle mounted on the nozzle seat in a stationary manner such that
when the nozzle seat is turned with respect to the lighter body,
the gas emitting nozzle is correspondingly supported by the nozzle
seat so as to ensure the gas ejecting at the gas emitting
nozzle.
[0010] Another object of the present invention is to provide a
piezoelectric lighter, which does not require to alter the original
structural design of the lighter so as to minimize the
manufacturing cost of the lighter incorporating with the nozzle
head.
[0011] Another object of the present invention is to provide a
piezoelectric lighter, wherein no expensive or complicated
mechanism is required to employ in the piezoelectric lighter, so
that the present invention successfully provides an economic and
efficient solution not only for allowing the nozzle head to be
turned to adjust the ignition angle of the lighter but also for
facilitating the practical use of the lighter.
[0012] Accordingly, in order to accomplish the above objects, the
present invention provides a piezoelectric lighter, comprising:
[0013] a lighter body having a liquefied gas storage and a gas tube
communicatively extending therefrom;
[0014] a piezoelectric unit, which is disposed in the lighter body
for generating piezoelectricity, comprising a movable operating
part extended upwardly and an ignition tip, wherein when the
movable operating part is depressed downwardly, sparks are
generated from the ignition tip;
[0015] a pusher button slidably mounted to the lighter body to
depress the movable operating part of the piezoelectric unit and to
release a flow of gas from the liquefied gas storage through the
gas tube at the same time;
[0016] a nozzle head comprising a nozzle seat and a gas emitting
nozzle supported on the nozzle seat in a stationary manner for
controlling the gas ejecting at the gas emitting nozzle; and
[0017] a nozzle joint, which is movably coupling the nozzle head
with the lighter body, having a guiding slot allowing the gas tube
extending to the gas emitting nozzle and the ignition tip of the
piezoelectric unit extending to a position closed to the gas
emitting nozzle, wherein the nozzle seat is adapted to be
selectively turned with respect to the lighter body via the nozzle
joint to selectively adjust an orientation of the gas emitting
nozzle so as to adjust an gas ejecting angle of the nozzle head
with respect to the lighter body.
[0018] These and other objectives, features, and advantages of the
present invention will become apparent from the following detailed

when the movable operating part 21 is depressed downwardly, sparks
are generated from the ignition tip 22.
[0026] The pusher button 30 is slidably mounted to the lighter body
10 to depress the movable operating part 21 of the piezoelectric
unit 20 and to release a flow of gas from the liquefied gas storage
11 through the gas tube 12 at the same time.
[0027] The piezoelectric lighter further comprises a nozzle head 40
and a nozzle joint 50 movably coupling the nozzle head 40 with the
lighter body 10.
[0028] The nozzle head 40 comprises a nozzle seat 41 and a gas
emitting nozzle 42 supported on the nozzle seat 41 in a stationary
manner for controlling the gas ejecting at the gas emitting nozzle
42.
[0029] The nozzle joint 50 has a guiding slot 501 allowing the gas
tube 12 extending to the gas emitting nozzle 42 and the ignition
tip 22 of the piezoelectric unit 20 extending to a position closed
to the gas emitting nozzle 42, wherein the nozzle seat 41 is
adapted to be selectively turned with respect to the lighter body
10 via the nozzle joint 50 to selectively adjust an orientation of
the gas emitting nozzle 42 so as to adjust an gas ejecting angle of
the nozzle head 40 with respect to the lighter body 10.
[0030] According to the preferred embodiment, the lighter body 10
has a U-shaped top portion defining two inner sidewalls 101 and a
top ceiling wall 102 to receive the nozzle head 40 between the two
inner sidewalls 101 on top of the tope ceiling wall 102. The
lighter body 10 further has a pusher slot 13 formed on a sidewall
to guide the pusher button 30 sliding on the lighter body 10.
[0031] The gas tube 12 is made of flexible material such as plastic
adapted to flexibly extend from the liquefied gas storage 11 to the
gas emitting nozzle 42 to guide the gas flowing thereto.
[0032] The lighter body 10 further comprises a gas releasable valve
14 operatively mounted on the liquefied gas storage 11 for
controlling the gas flowing therefrom and a gas lever 15, which is
disposed in the lighter body 10 in a pivotal movable manner, having
an engaging end 151 engaged with the gas releasable valve 14 and a
depressible end 152 arranged in such a manner that when the
depressible end 152 of the gas lever 15 is depressed downwardly,
the engaging end 151 of the gas lever 15 lifts up the gas
releasable valve 14 for releasing gas from the liquefied gas
storage 11.
[0033] As shown in FIG. 2, the pusher button 30, which is slidably
mounted on the sidewall of the lighter body 10 along the pusher
slot 13, has a depressing arm 31 extended into the lighter body 10
to rest on top of the movable operating part 21 of the
piezoelectric unit 20 and arranged in such a manner that when the
pusher button 30 is depressed downwardly, the movable operating
part 21 of the piezoelectric unit 20 and the depressible end 152 of
the gas lever 15 are respectively depressed at the same time to
generate the sparks and to release the gas so as to ignite the
piezoelectric lighter.
[0034] The nozzle seat 41 comprises a supporting platform 411
substantially supporting the gas emitting nozzle 42 in a stationary
manner to retain the gas tube 12 connecting to the gas emitting
nozzle 42 in a gas communicating manner, wherein the ignition tip
22 of the piezoelectric unit 20 is securely mounted to the nozzle
seat 41 to retain the ignition tip 22 of the piezoelectric unit 20
at a position closed to the gas emitting nozzle 42 such that when
the nozzle seat 41 is driven to turn, the gas tube 12 and the
ignition tip 22 of the piezoelectric unit 20 are retained in
position for allowing the gas flowing towards the gas emitting
nozzle 42 and the sparks generated at the ignition tip 22 of the
piezoelectric unit 20 towards the gas emitting nozzle 42
respectively.
[0035] The nozzle head 40 further comprises a windshield 43, having
a top flame opening 431, securely mounted to the nozzle seat 41 to
enclose the gas emitting nozzle 42 at a position that the gas
emitting nozzle 42 is aligned with the top flame opening 431. The
windshield 43 further has two opposing side stopper surfaces 432
adapted to bias against the top ceiling wall 102 of the lighter
body 10 so as to limit a pivot movement of the nozzle head 40.
Accordingly, the nozzle head 40 is adapted to pivotally turn
180.degree. between the two inner sidewalls 101 of the lighter body
10. Therefore, the two side stopper surfaces 432 of the windshield
43 prevent the over-turning of the nozzle head 40.
[0036] As shown in FIG. 3, the nozzle joint 50 comprises two pivot
shafts 51 outwardly and integrally extended from two sides of the
nozzle seat 41 to rotatably mount to the inner sidewalls 101 of the
lighter body 10 respectively so as to allow the nozzle head 40

formed on each of the pivot shafts 51 as a guiding through channel
such that the gas tube 12 is extended through one of the pivot
shafts 51 to communicatively connect to the gas emitting tube 42
while the ignition tip 22 of the piezoelectric unit 20 is extended
through another pivot shaft 51 to a position closed to the gas
emitting nozzle 42.
[0037] According to the present invention, the nozzle head 40 can
be normally turned at a position that the gas emitting nozzle 42 is
in an upright manner as a regular piezoelectric lighter such that
when the pusher button 30 is depressed downwardly, the gas ejecting
from the gas emitting nozzle 42 is ignited at the orientation of
the gas emitting nozzle 42. When the nozzle head 40 is pivotally
turned to adjust the orientation of the gas emitting nozzle 42 with
respect to the lighter body 10, the gas is ejected correspondingly
to adjust the igniting angle of the piezoelectric lighter. It is
worth to mention that when the nozzle head 40 is pivotally turned,
the nozzle seat 41 retains the gas tube 12 and the ignition tip 22
of the piezoelectric unit 20 in position so as to ensure the gas
ejecting at the gas emitting nozzle 42 and being ignited
properly.
[0038] As shown in FIGS. 4 and 5, a piezoelectric lighter of a
second embodiment illustrates an alternative mode of the first
embodiment of the present invention, wherein the nozzle head 40' is
adapted to turn in different direction via the nozzle joint 50' in
comparison with the first embodiment.
[0039] As shown in FIG. 4, the piezoelectric lighter of the second
embodiment has a structural configuration same as the structure of
the piezoelectric lighter of the first embodiment, expect the shape
of the lighter body 10', the nozzle head 40' and the nozzle 50',
wherein the lighter body 10' has a top ceiling wall 102' pivotally
supporting the nozzle head 40' via the nozzle joint 50', as shown
in FIG. 5.
[0040] The nozzle seat 41' comprises a supporting platform 411'
substantially supporting the gas emitting nozzle 42' in a
stationary manner to retain the gas tube 12 connecting to the gas
emitting nozzle 42' in a gas communicating manner, wherein the
ignition tip 22 of the piezoelectric unit 20 is securely mounted to
the nozzle seat 41' to retain the ignition tip 22 of the
piezoelectric unit 20 at a position closed to the gas emitting
nozzle 42' such that when the nozzle seat 41' is driven to turn,
the gas tube 12 and the ignition tip 22 of the piezoelectric unit
20 are retained in position for allowing the gas flowing towards
the gas emitting nozzle 42' and the sparks generated at the
ignition tip 22 of the piezoelectric unit 20 towards the gas
emitting nozzle 42' respectively. As shown in FIG. 4, the gas
emitting nozzle 42' is supported by the nozzle seat 41' at a
position transversely above the top ceiling wall 102' of the
lighter body 10'.
[0041] The nozzle head 40' further comprises a windshield 43',
having a side flame opening 431', securely mounted to the nozzle
seat 41' to enclose the gas emitting nozzle 42' at a position that
the gas emitting nozzle 42' is aligned with the side flame opening
431'. Accordingly, the windshield 43' has a tubular structure that
the nozzle seat 41' is securely mounted within the windshield
43'.
[0042] As shown in FIG. 4, the nozzle joint 50' comprises a pivot
shaft 51' downwardly extended from the nozzle seat 41' to rotatably
mount to the top ceiling wall 102' of the lighter body 10' so as to
allow the nozzle head 40' pivotally turning thereon, wherein the
guiding slot 501' is formed at the pivot shaft 51' as a guiding
through channel such that the gas tube 12 and the ignition tip 22
of the piezoelectric unit 20 are respectively extended through the
pivot shaft 51' to communicatively connect to the gas emitting
nozzle 42' and to a position closed to the gas emitting nozzle 42'.
Accordingly, the pivot shaft 51' is integrally and downwardly
extended from the windshield 43' wherein the gas tube 12 and the
ignition tip 22 of the piezoelectric unit 20 are extended through
the windshield 43' to communicate with the gas emitting nozzle
42'.
[0043] The pivot shaft 51' has a stopper edge 511' adapted to bias
against the top ceiling wall 102' of the lighter body 10' so as to
limit a pivot movement of the nozzle head 40'. Accordingly, the
nozzle head 40 is adapted to pivotally turn more than 180.degree.
on the top ceiling wall 102' of the lighter body 10'. A blocking
edge 512' is formed in the lighter body 10' at the pivot shaft 51'
to block the pivot movement of the nozzle head 40' when the stopper
edge 511' of the pivot shaft 51' reaches the blocking edge 512' of
the lighter body 10'. Therefore, the stopper edge 511' of the pivot
shaft 51' prevents the over-turning of the nozzle head 40'.
[0044] One skilled in the art will understand that the embodiment
of the present invention as shown in the drawings and described
above is exemplary only and not intended to be limiting.
