Description
Technical field
The utility model relates to the lighter field, heavy formula safe lighter after especially a kind of elder generation is light.
Background technology
Lighter, burning torch are widely used as a kind of daily igniter.
Igniter commonly used is that a kind of inflammable gases such as butagas, natural gas that utilize are the electronic ignition utensil of fuel at present, its usually directly press...with one's finger hand of pressing of pressure point fire device emits sparks piezoelectricity in the piezoelectric device in the igniter to light inflammable gas to produce flare.Owing to himself flammable gas being housed; in the situation that do not establish safety piece and increase the weight of operating physical force; press that to press hand in the igniter unrestricted; be not intended to maloperation, the child plays or have the unexpected percussion igniter of hard object press hand the time; very easily light igniter, injury children even endanger public security.Therefore, some areas and country are to the igniter of not establishing safeties or will expressly forbid production and selling.
The igniter of existing installation insurance device generally arranges locking mechanism pressing hand, namely when it is in latched position, pressing hand can't press because being stopped by it, only has the lock-out state of removing igniter, the user could successfully operate igniter, but owing to needing to increase safety insurance mechanism, increase cost; In addition, the lighter user is when using safe lighter, owing to needing at least two actions to finish whole igniting action, complicated operation is easily lost market.
The utility model content
The purpose of this utility model is heavy formula safe lighter provide a kind of elder generation light in order to solve above-mentioned the deficiencies in the prior art after, can effectively avoid child's unconscious operation and the potential safety hazard brought.
In order to achieve the above object, the light rear heavy formula safe lighter of a kind of elder generation that the utility model is designed, comprise housing, place the oil groove in the housing, piezoelectric element and go out pneumatic module, describedly go out the skid plate that pneumatic module comprises that air outlet valve and control air outlet valve open and close, described piezoelectric element comprises the piezoelectricity push rod of piezoelectricity shell and the upper and lower displacement of relative piezoelectricity shell energy, described piezoelectric element top is provided with the hand of pressing that can drive the upper and lower displacement of piezoelectricity shell, 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, be provided with the space between described block and the piezoelectricity push rod, described piezoelectricity push rod overcoat has a spring, and described spring-loaded is on block.
Thereby the piezoelectric element of the technical program is to make the upper and lower displacement relative to the piezoelectricity shell of piezoelectricity push rod play the effect of igniting by pressing the piezoelectricity shell.Press subordinate on time, because the compression stress of spring is less than the power of beating of pressing of piezoelectric element, make in advance compression of spring, piezoelectric element integral body moves down, when block is conflicted in piezoelectricity push rod bottom, requiredly increase by beating power, at this moment lower by power be the igniting of piezoelectric element required by the power of beating, the piezoelectricity shell continues to move down, and the piezoelectricity push rod is static, and piezoelectricity shell one side is utilized lever principle simultaneously, and an end of skid plate is moved down, the other end lifts air outlet valve, make air release (structure that drives the skid plate displacement is ripe at present, therefore not at this detailed description), last piezoelectric element culminates, the piezoelectric element generation current is lighted the gas of release.Press hand operated power heavy after first light, operate comfortablely, and effectively avoid child's unconscious operation and the potential safety hazard brought; Adopt the wireless piezoelectric assembly, assemble more convenient.
Improve and replenish as the further of said structure, the utility model also comprises any combination of following additional technical feature or these features:
The inner side edge of described piezoelectricity shell is provided with projection, described projection in above the skid plate and the gap between projection and the skid plate more than or equal to the space between block and piezoelectricity push rod, when the piezoelectricity shell moves down by the displacement of protruding conflict skid plate, reliable transmission; And the assurance skid plate is not opened air outlet valve too early, shortens the time difference that skid plate is opened air outlet valve and piezoelectric element generation current, reduces the waste of gas in the 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, described groove be positioned at described plush copper under, play the effect of guiding.
Described plush copper outer ring sleeve has yielding rubber, the piezoelectricity push rod be moved to downwards yielding rubber conflict to block and yielding rubber can't deformation till, play cushioning effect.
Described block is the oil groove wall, and block also is the cell wall of oil groove when playing conflict piezoelectricity push rod, and is rational in infrastructure.
Described piezoelectric element is the wireless piezoelectric assembly, assembles more convenient.
The described described piezoelectricity shell of subordinate side's conflict connection of pressing, transmission is more reliable.
Described block is provided with the cylinder of projection, and described spring housing is located at outside the 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, and the piezoelectricity push rod is played certain location and guiding slips into effect.
Heavy formula safe lighter after a kind of elder generation that the utility model obtains is light, by being inverted piezoelectric element, the piezoelectricity push rod is arranged down, between piezoelectricity push rod and block, the space is set, so that press hand on time downwards, piezoelectric element has the idle stroke to bottom offset, press hand continue lower on time, heavy after the larger pressing force of demand motive piezoelectric element igniting then, pressing force are light first, operate comfortablely, and effectively avoid child's unconscious operation and the potential safety hazard brought; Adopt the wireless piezoelectric assembly, assemble more convenient.
