Abstract
The present invention relates to a lighter with a simple safety device, which comprises a frame, a wind blocking cover, a gas outlet valve, a gas pressing plate, a fuel storage cavity, a piezoelectric mechanism (electronic) 2 which can generate electric sparks, and a pressing knob 1, wherein a support elastic body 3 is arranged below the piezoelectric mechanism, and the position corresponding to the piezoelectric mechanism is provided with a movable switch device 23 which can prevent the piezoelectric mechanism from moving. When the movable switch device is in a free state, the piezoelectric mechanism 2 can not generate electric sparks because of the retraction function of the support elastic body 3. When the movable switch device is pressed downwards, the part of the piezoelectric mechanism close to the support elastic body is clamped and can not move, and the piezoelectric mechanism can generate electric sparks by pressing downwards the pressing knob.
Description
Technical field
The present invention relates to a kind of igniter, especially a kind of safety lighter with the piezoelectric device igniting
Background technology
The ordinary electronic lighter structure is simple, security is low.The complex structure that existing safety lighter has is the button insurance safety lighter of 03211463.x as China Patent No., and safety device has more than ten parts to constitute; The structural strength that has is lower, is easy to damage, and be 00255436.4 to have the lighter of safeties as China Patent No., the adult is not opening the safeties situation, the fragile lighter of push button.Though the safety device of these safety lighters has limited children's use, thumb had a plurality of additional move when the adult used, and this also makes troubles to the adult.
Summary of the invention
In order to overcome existing safety lighter safety device complex structure, fragile, the awkward problem of being grown up the invention provides a kind of safety lighter, and this lighter safety device structure is comparatively simple, and is not fragile, and it is easy to use to be grown up, and safe in utilization.
The technical solution adopted for the present invention to solve the technical problems is: a kind of lighter, comprise frame, windshield, air outlet valve, the plate of calming the anger, fuel storage chamber, produce electric spark piezoelectric device (electronics just), press press button, in piezoelectric device (electronics) below a support elastic body is arranged, and piezoelectric device (electronics) correspondence position there is a movable switch device.The effect of movable switch device is moving of control piezoelectric device (electronics): when the movable switch device was in free state, piezoelectric device (electronics) can move up and down in its mounting groove; When the movable switch device is depressed, then piezoelectric device (electronics) is stuck and can not moves down, and realizes the control to piezoelectric device.
(1) when the movable switch device is in free state, piezoelectric device can move up and down in its mounting groove.As shown in Figure 1, this is principle of the invention figure, omit known parts such as frame, windshield, air outlet valve, the plate of calming the anger, fuel storage chamber among Fig. 1, in piezoelectric device (electronics) 2 belows a support elastic body 3 is arranged, and piezoelectric device (electronics just) correspondence position is provided with a movable switch device 4.If the sparking stroke of piezoelectric device is Lfh0 (a sparking stroke be meant piezoelectric device get angry to want compressed length), pressing down stroke by the press button maximum is Lay0, and Lay0 must be more than or equal to Lfh0.When by press button 1 to pressing down Lay length, if piezoelectric device 2 shrinks Lyd, support elastic body 3 shrinks Lzc, Lay=Lyd+Lzc is then arranged, the elastomer that selection has suitable stiffness factor supports, as long as satisfy: press and press range Lay0 under the press button, Lzc is greater than (Lay0-Lfh0) for support elastic body amount of contraction, and piezoelectric device can not produce electric spark.
Because: Lay=Lyd+Lzc
Lzc＞(Lay0-Lfh0)
When Lay=Lay0, can derive Lyd＜Lfh0, piezoelectric device does not reach sparking stroke Lfh0, just can not produce electric spark.
(2) be depressed when the movable switch device, then piezoelectric device (electronics just) is stuck and can not moves down, owing to press down the sparking stroke of stroke greater than piezoelectric device by the downward maximum of press button, presses down by press button and can make piezoelectric device produce electric spark.Must depress the movable switch device at first consciously when using this lighter, depress by press button again and just can make the lighter sparking, this uses to children has increased difficulty; Form the people when holding lighter, depress the movable switch device, be easy to use.Particularly, in the time of need striking sparks repeatedly, more can show the advantage of the safety device of this lighter in that once igniting is unsuccessful.This safety device had both limited children's accident and had used, and did not change adult's use habit again.The adult directly depresses by press button when not depressing the movable switch device, can not damage lighter, also can not strike sparks, and uses safer.
The movable switch device has at least a part to be exposed on the shell or stretches out shell among the present invention, is convenient to finger and stirs.
Piezoelectric device can move up and down in mounting groove.
What the movable switch device limited is moving down near this part piezoelectric device of support elastic body (electronics just).
If the sparking stroke of piezoelectric device is Lfh0 (a sparking stroke be meant piezoelectric device get angry to want compressed length), pressing down stroke by the press button maximum is Lay0, and Lay0 must be more than or equal to Lfh0.
Because piezoelectric device can move up and down in mounting groove, so the conductor wire of piezoelectric device will have enough length.
