Description
Technical field
The present invention relates to lighter field, especially a kind of first light rear heavy formula safe lighter.
Background technology
Lighter, burning torch, as the daily igniter of one, are widely used.
Igniter conventional is at present a kind of electronic ignition utensil utilizing the inflammable gas such as butagas, natural gas to be fuel, what it directly pressed with finger igniter usually presses hand, the piezoelectricity in the piezoelectric device in igniter is emitted sparks light inflammable gas to produce flare.Because himself is equipped with flammable gas; when not establishing safety piece and increasing the weight of operating physical force; hand is pressed unrestricted in pressing igniter; be not intended to maloperation, child play or have the unexpected percussion igniter of hard object part press hand time; very easily light igniter, injury children even endanger public security.Therefore, some areas and country are to not establishing the igniter of safeties or expressly will forbid production and selling.
The igniter of existing installation insurance device generally arranges locking mechanism pressing hand, namely when it is in latched position, press hand cannot press because being stopped by it, only has the lock-out state removing igniter, user's ability Successful Operation igniter, but because needs increase safety insurance mechanism, increase cost; In addition, lighter user, when using safe lighter, because needs at least two actions complete whole firing action, complicated operation, easily loses market.
Summary of the invention
The object of the invention is in order to solve above-mentioned the deficiencies in the prior art provide a kind of first light after heavy formula safe lighter, effectively can avoid the unconscious operation of child and the potential safety hazard brought.
In order to achieve the above object, one designed by the present invention is light rear heavy formula safe lighter first, comprise housing, be placed in the oil groove in housing, piezoelectric element and go out pneumatic module, the described pneumatic module that goes out comprises air outlet valve and the skid plate controlling air outlet valve opening and closing, described piezoelectric element comprises the piezoelectricity push rod of piezoelectricity shell and the upper and lower displacement of relative piezoelectricity shell energy, be provided with above described piezoelectric element can drive the upper and lower displacement of piezoelectricity shell press hand, it is characterized in that described piezoelectricity push rod is positioned at the downside of described piezoelectricity shell, the below of described piezoelectricity push rod is provided with a block, space is provided with between described block and piezoelectricity push rod, described piezoelectricity push rod overcoat has a spring, described spring-loaded is on block.
The piezoelectric element of the technical program is made the upper and lower displacement relative to piezoelectricity shell of piezoelectricity push rod by pressing piezoelectricity shell thus played the effect of igniting.Press subordinate on time, compression stress due to spring be less than piezoelectric element by the power of beating, spring is compressed in advance, piezoelectric element entirety moves down, when block is conflicted in piezoelectricity push rod bottom, required by playing power increase, pressing needed for lower igniting of pressing power and piezoelectric element now beats power, piezoelectricity shell continues to move down, and piezoelectricity push rod is static, piezoelectricity shell side utilizes lever principle simultaneously, one end of skid plate is moved down, the other end lifts air outlet valve, air release is made (to drive the structure of skid plate displacement more ripe at present, therefore do not describe in detail at this), last piezoelectric element culminates, piezoelectric element generation current, make the gas ignition of release.Press hand operated power first light rear heavy, operate comfortable, and the potential safety hazard effectively avoided the unconscious operation of child and bring; Adopt wireless piezoelectric assembly, assemble more convenient.
Improving further and supplementing as said structure, the present invention also comprises any combination of following additional technical feature or these features:
The inner side edge of described piezoelectricity shell is provided with projection, and the gap of described projection above skid plate and between projection and skid plate is more than or equal to the space between block and piezoelectricity push rod, by the displacement of protruding conflict skid plate when piezoelectricity shell moves down, and reliable transmission; And ensure that skid plate prematurely opens air outlet valve, shorten the time difference that skid plate opens air outlet valve and piezoelectric element generation current, reduce the waste of gas in oil groove.
Described piezoelectricity push rod lower end is provided with a plush copper, and described block upper surface has the groove that a size is a bit larger tham above-mentioned plush copper, and described groove is positioned at immediately below described plush copper, plays the effect of guiding.
Described plush copper outer ring sleeve has yielding rubber, and piezoelectricity push rod is moved to yielding rubber downwards and conflicts to block and yielding rubber deformation, cannot play cushioning effect.
Described block is oil groove wall, and block is also the cell wall of oil groove while playing conflict piezoelectricity push rod, rational in infrastructure.
Described piezoelectric element is wireless piezoelectric assembly, assembles more convenient.
Described presses the piezoelectricity shell of conflicting described in connection subordinate side, and transmission is more reliable.
Described block is provided with protruding cylinder, and described spring housing is located at outside described cylinder, plays the position-limiting action to spring.
Described column top is provided with spherical groove, and the lower surface of described piezoelectricity push rod is spherical, plays certain location and guiding slips into effect to piezoelectricity push rod.
The one that the present invention obtains is light rear heavy formula safe lighter first, by being inverted piezoelectric element, piezoelectricity push rod is arranged down, space is set between piezoelectricity push rod and block, make to press hand on time downwards, piezoelectric element has the idle stroke to bottom offset, press hand continue under on time, then need the larger pressing force driving piezoelectric element igniting, heavy after pressing force is first light, operate comfortable, and the potential safety hazard effectively avoided the unconscious operation of child and bring; Adopt wireless piezoelectric assembly, assemble more convenient.
