Description
Technical field
The utility model relates to a kind of igniter, is specifically related to the igniter that a kind of operating physical force increases the weight of.
Background technology
Lighter, burning torch are widely used as a kind of daily igniter.
Igniter commonly used at present is a kind of electronic ignition utensil that utilizes inflammable gases such as butagas, natural gas for fuel, its directly press...with one's finger usually button ignition switch 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 is housed; do not establishing safety piece and increasing the weight of under the situation of operating physical force; it is unrestricted to push in the igniter button ignition switch; when being not intended to maloperation, the child plays or the button ignition switch of the unexpected percussion igniter of hard object being arranged; very easily light igniter, injury children even endanger public security.Therefore, area that has 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 is provided with locking mechanism at button ignition switch, promptly when it is in latched position, button ignition switch can't be pressed because of being stopped by it, has only the lock-out state of removing igniter, the user could successfully operate igniter, but, increase cost owing to need to increase security insurance mechanism; In addition, the lighter user is when using the insurance lighter, owing to need at least two actions to finish whole igniting action, complicated operation is lost market easily.
The another kind of structure of the igniter of existing installation insurance device is to increase the weight of igniting push-botton operation power in the igniter.Increasing the weight of the button ignition switch operating physical force can have following dual mode to realize:
Mode 1: increase the spring-operated power of piezoelectricity inside in the igniter, make the button ignition switch operating physical force,, therefore can realize preventing the purpose of child because the hand-power of children below 5 years old is difficult to start the operating physical force of 4.5Kg greater than 4.5Kg.
Mode 2: U.S. Pat 6267582 discloses a kind of igniter that increases the weight of operating physical force, its piezoelectricity that directly contacts with button ignition switch outside in igniter, increasing a secondary spring, make button ignition switch when pressing down piezoelectricity, also directly push secondary spring, thereby increase the operating physical force of button ignition switch, make the button ignition switch operating physical force greater than 4.5Kg, because the hand-power of children below 5 years old is difficult to start the operating physical force of 4.5Kg, therefore can realize preventing the purpose of child.
Drawbacks such as but the igniter that more than increases the weight of the button ignition switch operating physical force exists the automation efficiency of assembling not high, and the igniting life-span is not long are lost market easily.
The utility model content
The technical assignment of technical problem to be solved in the utility model and proposition is to overcome above-mentioned prior art defective, the igniter that increases the weight of the button ignition switch operating physical force of the increasingly automated assembling of a kind of usefulness is provided, effectively avoids child's unconscious operation and the potential safety hazard brought.
The technical solution of the utility model is such: a kind of igniter that increases the weight of operating physical force, comprise oil groove, igniter and air-out apparatus, wherein air-out apparatus comprises air outlet valve, skid plate, igniter comprises button ignition switch, piezoelectricity and the piezoelectricity rubber that is positioned under the piezoelectricity, described piezoelectricity comprises piezoelectricity housing and piezoelectricity push rod, described piezoelectricity push rod can stretch in the piezoelectricity housing under the external force effect, and after external force is eliminated, be returned to original position under the effect of its inner push rod spring, be with secondary spring on the described piezoelectricity push rod, it is characterized in that described piezoelectricity push rod upper end is provided with the piezoelectricity cap, the secondary spring that is with on the piezoelectricity push rod can not be broken away from from the piezoelectricity push rod, improve the automation efficiency of assembling.Conflict at button ignition switch in described piezoelectricity cap upper end, when ignition location, the operating physical force of button ignition switch is greater than 4.5Kg.
Push button ignition switch, the expenditure knee-joint of button ignition switch lower end contacts skid plate, simultaneously skid plate is promoted downwards near piezoelectricity one end, at this moment skid plate passes through fulcrum, its end that is connected on the air outlet valve is moved up, discharge inflammable gas thereby open air outlet valve, piezoelectricity produces instant high-voltage thereupon and inspires electric spark, and then light gas, form flame.The bottom of oil groove is provided with intake valve, and intake valve is used to add and fills inflammable gas, and they assemble connection in the usual way.
Description of drawings
Fig. 1 is the structural representation that is in safety position of the present utility model.
Fig. 2 is the piezoelectricity cap and the push rod joint portion enlarged diagram of the utility model piezoelectricity.
The specific embodiment
As shown in Figure 1, the parts that constitute the utility model prior art have: comprise oil groove 1, igniter and air-out apparatus, wherein air-out apparatus comprises air outlet valve 2, skid plate 3, igniter comprises button ignition switch 4, piezoelectricity 5 and be positioned at the piezoelectricity rubber 6 that piezoelectricity is used to cushion for 5 times, described piezoelectricity comprises piezoelectricity housing 7 and piezoelectricity push rod 8, described piezoelectricity push rod 8 can stretch in the piezoelectricity housing 7 under the external force effect, and after external force is eliminated, be returned to original position under the effect of its inner push rod spring, be with secondary spring 9 on the described piezoelectricity push rod 8, described piezoelectricity push rod 8 upper ends are provided with piezoelectricity cap 10, the secondary spring 9 that is with on the piezoelectricity push rod 8 can not be broken away from from piezoelectricity push rod 8, improve the automation efficiency of assembling.Conflict at button ignition switch 4 in described piezoelectricity cap 10 upper ends, when ignition location, the operating physical force of button ignition switch is greater than 4.5Kg.
