Abstract

The utility model relates to a safety lighter, consisting of an oil tank, an ignition device, a gas outlet device, an air cover arranged on the upper end of the gas outlet device, wherein a position-limit block with a distance away from the upper surface of the pressing hand less than 4.5 mm is arranged at the two sides of the upper end where the oil tank is matched, the length of the position-limit block is shorter than the length of the pressing hand. Only the position of the acting force is intentionally selected to keep away from the blocking of the upper end bracket of the oil tank, the pressing hand can be pressed downwards and the lighter is ignited. Consequently, all the accidents and property loss caused by the lighter operation of children are avoided.

Description

A kind of insurance lighter

[technical field]

The utility model relates to a kind of electronic lighter, particularly a kind of insurance lighter.

[background technology]

Lighter at present commonly used is a kind of electronic ignition utensil that utilizes inflammable gases such as butagas, natural gas for fuel, and its sub-lighter of piezoelectricity that directly press...withes one's finger is usually pressed hand, piezoelectricity in the piezoelectric device is emitted sparks light inflammable gas to produce flare.Owing to himself flammable gas is housed, do not establishing under the situation of safety piece, push that to press hand unrestricted, when being not intended to maloperation, the child plays or having the unexpected percussion lighter of hard object to press hand, very easily light lighter, injury children even endanger public security.Therefore, area that has and country are to the lighter of not establishing insurance or will expressly forbid production and selling.

Existing lighter generally is provided with locking mechanism to button ignition switch, and promptly when it was in latched position, button ignition switch can't be pressed because of being stopped by it, but owing to need to increase security insurance mechanism, increases cost; 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.

[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 insurance lighter that provides a kind of utilization to dwindle the effective area that the user pushes can effectively be avoided child's unconscious operation and the potential safety hazard brought.

The technical solution of the utility model is such: the insurance electronic lighter, mainly comprise oil groove, be installed in igniter and air-out apparatus in the oil groove, and the fan housing that is positioned at the air-out apparatus upper end, wherein air-out apparatus comprises air outlet valve, skid plate, igniter comprises presses hand, piezoelectricity and is positioned at piezoelectricity rubber under the piezoelectricity, it is characterized in that described oil groove and press the upper end that hand cooperates, there is limited block both sides outside pressing hand.Described limited block upper edge with press the entopic upper edge of hand distance less than 4.5mm.Described limited block length is less than pressing pushing degree.

The utility model has changed on the conventional piezoelectric insurance lighter, can not directly push and press hand, makes the mentality of designing of piezoelectricity discharge igniting simultaneously.At the simple understanding of child, adopt the method for reduction operation active area and limited block on the utility model, realize child below 5 years old is played safety effect the operation of piezoelectric lighter, and less to other lighter user's operating influence.

[specific embodiment]

As Fig. 1, shown in Figure 2, constitute that the utility model prior art comprises oil groove 1, presses hand 2, the piezoelectric device in oil groove 13, air-out mechanism 4, the skid plate 5 of between piezoelectric device 3 and air-out mechanism 4, giving vent to anger.Air-out mechanism 4 comprises air outlet valve 6; Be useful on the air-out needle 7 and the taking fire spring 8 of giving vent to anger in the air outlet valve 6; On air-out mechanism 4, be provided with flame adjusting ring 9 to adjust tolerance.Piezoelectric device 3 comprises piezoelectricity 10, the piezoelectricity rubber 11 that piezoelectricity 10 lower ends are used to cushion.The top of piezoelectricity 10 is the piezoelectricity caps 12 that act on skid plate 5, and piezoelectricity cap top is to press hand 2.And the fan housing 13 that is positioned at whole air-out mechanism 4 upper ends.With the bottom 15 that plays sealing function.

Normally push any position of pressing hand 2, press hand 2 following piezoelectricity caps 12 and press down skid plate 5, make air-out needle 7 liftings, press down piezoelectricity 10 simultaneously, produce the high pressure spot spark, light the fuel gas that discharges from air-out needle 7, produce flame.

After external force disappears, under piezoelectricity 10 contained spring power effects, piezoelectricity cap 12, skid plate 5 and press hand 2 and be returned to the normal position, air-out needle 7 interrupts discharging fuel gas, fray-out of flame.

Practicality as shown in Figure 3, Figure 4 comprises oil groove 1, presses hand 2, the piezoelectric device in oil groove 13, air-out mechanism 4, the skid plate 5 of giving vent to anger between piezoelectric device 3 and air-out mechanism 4.Air-out mechanism 4 comprises air outlet valve 6; Be useful on the air-out needle 7 and the taking fire spring 8 of giving vent to anger in the air outlet valve 6; On air-out mechanism 4, be provided with flame adjusting ring 9 to adjust tolerance.Piezoelectric device 3 comprises piezoelectricity 10, the piezoelectricity rubber 11 that piezoelectricity 10 lower ends are used to cushion.The top of piezoelectricity 10 is the piezoelectricity caps 12 that act on skid plate 5, and piezoelectricity cap top is to press hand 2.Described oil groove 1 is with pressing the spacing block set 14 that both sides external that hand 2 cooperates respectively has position-limiting action.The upper edge of described spacing block set 14 with press the distance of hand 2 upper edges less than 4.5mm.The length of described spacing block set 14 is seen partly consumer's energy front and is pressed hand 2 less than the length of pressing hand 2, and the bottom 15 that plays sealing function.

Push when pressing hand 2 according to normal mode, operator's finger is owing to be subjected to the barrier effect of oil groove 1 upper limit projection 14, can not press down and press hand 2, make piezoelectricity 10 and skid plate 5 inoperative, thereby hinder the generation of whole igniting action, play the effect of insurance, particularly to the child below 5 years old, owing to do not know wherein, can not produce and be not intended to operation, thereby can avoid largely operating various fire incidents and the property loss that lighter causes because of child below 5 years old.

Have only when the operator is placed in finger and press hand 2, there is not part that the spacing block set 14 of oil groove 1 exists when beating, because spacing block set 14 does not play barrier effect to the operator, the piezoelectricity cap 12 of pressing subordinate face presses down skid plate 5, make air-out needle 7 liftings, press down piezoelectricity 10 simultaneously, produce the high pressure spot spark, light the fuel gas that discharges from air-out needle 7, produce flame.

The utility model includes but not limited to the foregoing description, and every lighter components of utilizing all belongs to protection domain of the present utility model to the stopping and selectively use by the safety structure of beating the position or other equivalent structure of operator finger.
