Description
Technical field
The present invention relates to a kind of lighter, particularly relate to a kind of child resistant lighter
Background technology
Lighter is the burning things which may cause a fire disaster machine, and it produces flame ignition article or other burning things which may cause a fire disaster.Lighter is by housing, fuel mechanism, and ignition mechanism and operating mechanism are formed.Fuel mechanism provides the part of fuel, and by using the fuel difference can divide fuel gas mechanism, alcohol mechanism etc. is fired in fuel oil mechanism.Ignition mechanism is the part that produces spark ignition fuel, by the method branch that produces spark electronic ignition mechanism and two kinds of friction flint ignition mechanisms is arranged.Two kinds of piezoelectric igniting mechanism and battery high-tension coil ignition mechanisms are arranged again in electronic ignition mechanism.The high-tension current of the high-tension current of piezoelectric igniting mechanism or battery high-tension coil ignition mechanism is the electric current that is used for producing the electric spark fire fuel, and we are called the firing circuit of electronic ignition mechanism the circuit that this electric current passes through.It is the gap that is used for producing the electric spark of fire fuel that a gap is arranged near the fuel outlet of fuel mechanism in this firing circuit, and we claim that it is an ignition gap.Operating mechanism is that the operation lighter is beaten the part of combustion, and it is being controlled ignition mechanism and is producing spark, and what there was a fuel door in fuel mechanism is also controlling closing and opening of fuel door.Press hand in the operating mechanism, pressing hand is exactly the part of staff direct control, and it can also have other function concurrently, and general lighter has one or two to press hand.General lighter fuel outlet from press the nearer volume of hand less be easy to carry to be mainly used in light cigarette.A kind of fuel outlet is mainly used in and lights other burning things which may cause a fire disaster from pressing lighter that hand volume far away seldom carries greatly, and this lighter often claims burning torch.Housing is a part of installing and protect fuel mechanism, ignition mechanism and operating mechanism.Whatever operating mechanism adult of general lighter and children are easy to operate to play combustion, like to play with a cigarette lighter easily burn oneself even cause that fire gives family and social Jonah of children.
In order to prevent that lighter from damaging children, the lighter that a lot of anti-children play combustion has been invented by various countries.U.S. Bic Corp is 00807069.5 at the application number of China's application, and the patent of utility lighter by name has just been described the lighter that a kind of children of preventing play combustion.This lighter electronic assembly (electronic ignition mechanism) is connected in first electric pathway and second electric pathway.First electric pathway is included in first gap (ignition gap) of outlet (fuel outlet).Second electric pathway has effectively and the invalid configuration form.The resistance of second electric pathway is less than the resistance of first electric pathway in the invalid configuration form, thereby the electric current that this electronic building brick is produced flows in second electric pathway selectively; The resistance of second electric pathway is greater than the resistance of first electric pathway in effective configuration, thereby electric current is flowed in first electric pathway selectively, and skips first gap and form spark, lights the fuel from fuels sources.This is a kind of lighter with electronic ignition mechanism as can be known from above-mentioned, the firing circuit of this electronic ignition mechanism is the circuit that two external circuit in parallel of a power supply are arranged, article one, external circuit is the ignition gap circuit, the second external circuit be can make resistance less than with greater than first external circuit circuit.This firing circuit be actually in the firing circuit of general electronic lighter electronic ignition mechanism, be parallel with can make resistance less than with firing circuit greater than second external circuit of ignition gap circuitous resistance.When the resistance of second external circuit less than first external circuit (ignition gap circuit) resistor current by second external circuit, by first external circuit, do not produce electric spark at ignition gap, lighter does not fire, this just has anti-children and plays the combustion effect; When the resistance of second external circuit became bigger than first external resistance, electric current just passed through first external circuit by second external circuit, and electric current just produces electric spark at ignition gap, and lighter can be operated and play combustion, and this plays combustion with regard to guaranteeing that the adult uses with lighter.But the resistance of this lighter firing circuit second external circuit must change by the position of operating knob, in the time will operating resistance that knob pushes second external circuit, just can operate lighter and play combustion greater than the position of first external resistance, this method of operating children learn easily, easily lighter is played combustion, so the effect that the anti-children of this lighter play combustion is bad.
Summary of the invention
The technical problem to be solved in the present invention is can make resistance less than improving with electronic lighter greater than second external circuit of ignition gap circuitous resistance to above-mentioned being parallel with in firing circuit, plays the reliable adult of combustion child resistant lighter easy to use so that a kind of anti-children to be provided.
The scheme that solves the problems of the technologies described above is: a kind of child resistant lighter, by housing, fuel mechanism, electronic ignition mechanism and operating mechanism are formed, be parallel with in the firing circuit of electronic ignition mechanism can make resistance less than with second external circuit greater than the ignition gap circuitous resistance, in the firing circuit of electronic ignition mechanism in parallel made resistance less than with second external circuit greater than the ignition gap circuitous resistance be Swing type switch in parallel, Swing type switch is installed in the lighter, Swing type switch is by moving contact, static contact, magnetic force spare and also can forming by other part, moving contact magnetic force spare and static contact relatively moves within the specific limits, moving contact has open position and closed position in its range of movement, magnetic force spare and moving contact can pass through magnetic interaction, moving contact stops at open position under magneticaction open Swing type switch, when Swing type switch is opened moving contact contact with static contact or the gap of moving contact and static contact less than ignition gap, moving contact stops at the lighter whipping and can overcome magnetic force when making the moving contact closed position down move to the closed position from open position Swing type switch is closed under inertia and gravity effect, the gap of moving contact and static contact was greater than ignition gap when Swing type switch was closed, and Swing type switch is closed the back and made the moving contact closed position also can not have gravity effect lower moving contact can get back to open position from the closed position at magnetic force down the time at lighter to make Swing type switch recover to open.
Below technical solution problem scheme is described
Swing type switch is an electric switch.Swing type switch is by moving contact, static contact, magnetic force spare and also can being made up of other part.Moving contact and static contact are made by conductor, and static contact can be exactly the termination of lead.Usually Swing type switch has first magnetic force spare of movable contact, one or two static contact, and the gap of two static contacts is greater than ignition gap when two static contacts.Here also to illustrate a bit when a plurality of (comprising two) and only calculate a moving contact when moving contact is linked together by conductor,, only calculate a static contact when a plurality of (comprising two) when static contact is linked together by conductor.It is exactly that the moving contact of Swing type switch and static contact or two static contacts are communicated with two poles with the ignition gap external circuit respectively and form external circuit in parallel that Swing type switch is parallel in the firing circuit.Swing type switch is installed in the lighter, and the part that is exactly Swing type switch directly or by other part is installed on the lighter part.
How the moving contact of Swing type switch is installed in the lighter is decided by the structure of moving contact.For making moving contact when motion frictional resistance little, often moving contact is made pendulum, pendulum is exactly the part of main off-axis one side of quality of can rotate around the axis.Pendulum can have only the friction in axle and hole when rotating outside the deacration resistance, and frictional resistance is little.When moving contact be when pendulum we just can cooperate moving contact is installed on the lighter part by axis hole, or be installed on the special part by the axis hole cooperation and refill in lighter.Outside the deacration resistance, can have only rolling friction during the ball motion, frictional resistance is also very little, also is fit to do moving contact.We just are installed in moving contact in the lighter part cavity or in the special part cavity and refill in lighter when moving contact is ball.
Magnetic force spare is can be by magnetic force and the interactional part of moving contact.First is that one of permanent magnet is that ferromagnet (ferromagnetic material adult) or two are permanent magnets for magnetic force spare and movable contact.But we require magnetic force spare and the interactional magnetic force of moving contact is attraction, so when all being permanent magnet, two of magnetic force spare and moving contacts require their opposite poles relative.The permanent magnet that has is that good conductor is to do moving contact, but we make permanent magnet with magnetic force spare usually, and moving contact is made ferromagnet.The magnetic force that moving contact is subjected to is exactly and the interactional attraction magnetic force of magnetic force spare.
Swing type switch is as two static contacts of a moving contact, during switch opens, each static contact can have a gap with moving contact respectively, moving contact and static contact just have two gaps like this, when two gaps, the moving contact of saying in the scheme and the gap of static contact be less than ignition gap, just refer to these two gaps and less than ignition gap.When Swing type switch is closed as two static contact switches of a moving contact, it is that moving contact and static contact have two gaps that each static contact has a gap with moving contact respectively, the moving contact of saying in the scheme and the gap of static contact be greater than ignition gap, just refer to these two gaps and greater than ignition gap.
When Swing type switch is opened since moving contact contacts with static contact or the gap of moving contact and static contact less than ignition gap, the resistance of Swing type switch circuit (second external circuit) is just less than the resistance of ignition gap circuit (first external circuit), therefore, electronic ignition mechanism does not just pass through ignition gap by Swing type switch when producing electric current, can not produce the electric spark of fire fuel at ignition gap, lighter can not be operated and play combustion.The gap of its moving contact and static contact is greater than ignition gap when Swing type switch is closed, so the resistance when Swing type switch is closed is greater than the ignition gap circuitous resistance, when producing electric current in electronic ignition mechanism like this, electric current is just by the ignition gap circuit, not by the Swing type switch circuit, electric current will produce the electric spark of fire fuel at ignition gap, and lighter can be operated and play combustion.Lighter can not be operated and play combustion when Swing type switch was opened as can be known from last analysis, and lighter could be operated and play combustion when Swing type switch was closed.
The moving contact closed position is exactly the open position closed position meaning below in the above of moving contact down.The moving contact closed position can be down the closed position roughly down.The lighter whipping is variable motion in short-term, and moving contact is done variable motion in short-term with lighter just can be because of inertia static contact and the motion of magnetic force spare relatively.Moving contact is near from magnetic force spare when open position, far away from magnetic force spare when the closed position, so, the attraction magnetic force that moving contact is subjected to when open position is big, when moving contact from open position when move in the closed position, the suffered magnetic force of moving contact is with leaving apart from becoming square decline, and the magnetic force that is subjected to when moving contact arrives the closed position is little, and the moving contact of Swing type switch stops at open position and makes switch opens under magneticaction usually.Only make the moving contact closed position down, only can not move to the closed position from open position Swing type switch is closed, when needing the lighter whipping to stop to make the moving contact closed position down Swing type switch is closed by the gravity moving contact of moving contact.Making method commonly used that Swing type switch closes is to place the moving contact closed position and get rid of when stopping (Here it is, and the lighter whipping stops at moving contact closed position a kind of situation down) moving contact to next and can overcome magnetic force leave open position and move to the closed position under inertia and gravity effect down in lighter, the magnetic force that is subjected to is little though moving contact arrives that effect of inertia behind the closed position disappears, and moving contact just is maintained in its closed position under the gravity effect Swing type switch is closed.As long as Swing type switch closes the back the closed position that makes moving contact by lighter not down the time, because at this moment the gravity of moving contact is opposite with magnetic force even commentaries on classics is identical with magnetic force direction, moving contact just can also can have at magnetic force and gets back to open position from the closed position under the gravity effect Swing type switch recovery is opened like this.
When lighter of the present invention used, the whipping lighter cut out Swing type switch just can to handle and presses hand lighter is played combustion as stated above, so this lighter of adult's use is easily.Lighter use the back if the lighter orientation change make the moving contact closed position not down Swing type switch recover again to open.The Swing type switch of this lighter does not have operating knob, children play combustion with lighter after can not Swing type switch being closed by the operation knob, even the accidental whipping lighter of children cuts out Swing type switch, but the lighter orientation change make the moving contact closed position not down the time Swing type switch recover again to have opened, children do not close Swing type switch and just play not so lighter, so this is that a kind of anti-children play the reliable lighter of combustion.The present invention just provides a kind of anti-children to play the reliable adult of combustion child resistant lighter easy to use like this.
For making the present invention improve the following optimization measure that remakes more:
Lighter head (lighter fuel outlet termination) up when 1, general lighter used.This lighter head-up the time Swing type switch moving contact closed position not necessarily down, Swing type switch is not necessarily closed.When make the moving contact closed position down lighter head lighter is not beaten when combustion up, just burning user's hand easily, also article are lighted in inconvenience.For this reason, we do the moving contact closed position of Swing type switch towards lighter bottom (with sparking head opposite end) like this lighter the moving contact closed position is just down head-up the time, during lighter of the present invention after use optimizing like this, can be head-up and get rid of when stopping Swing type switch to next and just close with lighter, just can resemble operation then and lighter be played combustion the common lighter, the adult uses just more convenient.Lighter use general horizontal placement moving contact closed position, back not down Swing type switch recover again to open.
2, we are provided with cushion pad at the place, closed position of Swing type switch moving contact, can alleviate moving contact moves to the closed position from open position collision and bounce-back like this.

Fig. 1 is the longitudinal section of lighter among the embodiment 1.
Fig. 2 is the partial sectional view of lighter among the embodiment 2.
The specific embodiment
Swing type switch is made up of moving contact 12, static contact, magnetic force spare 13, cushion pad 14.Magnetic force spare 13 is permanent magnets, and its upper and lower side is a magnetic pole.Magnetic force spare 13 is installed in lighter shell 1 chamber by magnetic shell 15.Lead 16 bottoms are installed on magnetic shell 15 outer wall grooves and housing 1 inwall, and its lower end is exactly the static contact of Swing type switch.Moving contact 12 is pendulum, is made by the ferromagnetic material steel, and its right-hand member has at the half front axle 17 of a straight line and back semiaxis, and its quality is mainly in the two-semiaxle left side.The half front axle 17 of moving contact 12 is installed in the π body 6 preceding plate holes, and back semiaxis is installed in plate 18 holes, π body 6 back and just moving contact 12 is directly installed on the π body 6, is installed in indirectly in the housing 1.Cushion pad 14 is sponges, and it clings in housing 1 chamber.Moving contact 12 is installed on the π body 6 and can rotates in magnetic force spare 13 and cushion pad 14 restricted portions relative to magnetic force spare 13 and static contact (lead 16 lower ends) around its semiaxis.Because magnetic force spare 13 is permanent magnets, moving contact 12 be ferromagnet they just by attracting magnetic interaction.It is exactly the open position of moving contact at its range of movement that moving contact 12 presses down the position that is parked in magnetic force spare 13 lower ends at this magneticaction.The little place 19 of moving contact 12 its left end when open position just contacts with lead 16 lower ends (static contact) and makes switch opens.It is exactly the closed position of moving contact at its range of movement that moving contact 12 left ends are pressed the position that is parked in cushion pad 14.Moving contact 12 when the closed position and the gap of static contact greater than ignition gap switch cuts out.The open position of Swing type switch moving contact is by the sparking heading, and the closed position is by the lighter bottom direction, and Here it is Swing type switch moving contact closed position is towards the situation of lighter bottom.
The electrode cable 20 of piezoelectric igniting mechanism 7 is piezoelectric igniting mechanism 7 one electrode outlet lines.The ignition trigger spare 10 of piezoelectric igniting mechanism 7 and lower end 21 all are another electrode eductions of piezoelectric igniting mechanism 7.Taking fire spring 22 is installed on the burner 5.Taking fire spring 22 is communicated with another electrode of piezoelectric igniting mechanism 7 by burner 5, skid plate 9 and ignition trigger spare 10.It is relative with taking fire spring 22 that the hole of inner cover 23 is passed in the termination of the electrode cable 20 of piezoelectric igniting mechanism 7, and their gap is exactly near the ignition gap of firing circuit fuel outlet.Electric current is just by electrode cable 20, ignition gap, taking fire spring 22, burner 5, skid plate 9 ignition trigger spares 10 when piezoelectric igniting mechanism 7 hits the living electricity of pressure, flow to another electrode and produce electric spark from an electrode of piezoelectric igniting mechanism, Here it is former firing circuit at ignition gap.
The termination of the upper end of lead 16 and electrode wires 20 all strips out insulating barrier and is through in the same hole of inner cover 23 and contacts, and the static contact of Swing type switch is that the lower end of lead 16 just is communicated with piezoelectric igniting mechanism one electrode by lead 16 and electrode cable 20 like this.The moving contact 12 of Swing type switch is communicated with another electrode of piezoelectric igniting mechanism by its semiaxis, π body 6 and piezoelectric igniting mechanism 7 lower ends.Swing type switch just is parallel in the firing circuit like this, and firing circuit just has two external circuit in parallel of a power supply like this, and its first external circuit is exactly the ignition gap circuit, and its second external circuit is exactly the Swing type switch circuit.
Swing type switch moving contact 12 is big against magnetic force that magnetic force spare 13 is subjected to when open position, and the magnetic force that far is subjected to from magnetic force spare 13 when the closed position is little.Because the closed position of Swing type switch moving contact 12 is towards the lighter bottom, the closed position of lighter moving contact head-up the time just down.Lighter head-up Swing type switch moving contact 12 magnetic force that moving contact 12 is subjected to when open position has the trend that moving contact 12 is clockwise rotated, the gravity that moving contact 12 is subjected to has the trend that moving contact 12 is rotated counterclockwise, and makes switch opens but the big moving contact 12 of magnetic force just stops at open position.Lighter is head-up got rid of when stopping to next, be exactly that the lighter whipping stops at the moving contact 12 closed positions a kind of situation down that makes, moving contact 12 just overcomes magnetic force and turns to the closed position from open position under inertia and gravity effect, though effect of inertia disappeared after moving contact 12 arrived the closed position, the little closed position that just stops under the gravity effect of the magnetic force that they are subjected in the closed position is closed whipping.After closing, Swing type switch do not make moving contact 12 closed positions not down the time up when the sparking head, the gravity of moving contact 12 is not opposite with magnetic force direction even identical, and moving contact 12 just also can have at magnetic force to be got back to open position and make Swing type switch recover to open under the gravity effect.Also can make moving contact get back to open position under effect of inertia by the whipping lighter after Swing type switch is closed makes Swing type switch recover to open.
Usually Swing type switch is opened, and using this lighter method commonly used is lighter head-up to be got rid of Swing type switch is closed just can handle to next press hand 8 lighter is played combustion.It is such that lighter is beaten the combustion process, and manipulation is pressed hand 8 and moved downward, and presses hand 8 one side pressures skid plate 9 is clockwise rotated, and presses on the other hand ignition trigger spare 10 is moved downward.Skid plate 9 rotates opens combustion gas from 5 mouthfuls of ejections of burner by burner 5 with air valve, the piezoelectric igniting mechanism 7 that puts in place of ignition trigger spare 10 motion subsequently hits to press and gives birth to, because at this moment Swing type switch is closed the gap of its moving contact 12 and static contact greater than ignition gap, the Swing type switch circuitous resistance is greater than first external resistance, electric current just produces electric spark by first external circuit at ignition gap, the combustion gas of ejection is lighted, and flame is gone here and there out from the burner 25 of fan housing 24.Lighter use back relieving is pressed hand 8 each part and is resetted, and air valve is closed fray-out of flame.If opening, Swing type switch just operates lighter, combustion gas also can be from 5 mouthfuls of ejections of burner, piezoelectric igniting mechanism 7 also can hit to press and give birth to, but because Swing type switch is being opened, moving contact 12 contacts with static contact, the resistance of Swing type switch circuit just is significantly smaller than first external resistance, and electric current just by the Swing type switch circuit, does not produce electric spark by first external circuit, ignition gap, the combustion gas of ejection can not be lighted, lighter does not fire.
When the adult uses the present embodiment lighter, lighter head-up can be got rid of Swing type switch to next and just close, just can resemble then and lighter be played combustion the operation common lighter, so this lighter of adult's use is easily.Swing type switch does not have operating knob, when playing this lighter, children can not Swing type switch be closed by the operation knob, even children are fired the whipping lighter by chance Swing type switch is closed, but the sparking head changes towards direction Swing type switch is opened, children do not close Swing type switch and do not fire this lighter with regard to playing, therefore, this lighter is that anti-children play the reliable lighter of combustion.
The Swing type switch of lighter among the embodiment 1 removed change the outfit that to go up moving contact be that the Swing type switch of ball just becomes embodiment 2 lighter.Fig. 2 is embodiment 2 lighter partial views.The high pad 26 of plastics is contained in former π body 6 positions in the lighter shell 1.Putting sheet metal 27 above the high pad 26 of plastics, the lower end 21 of piezoelectric igniting mechanism 7 is pressed in this above sheet metal 27.Switch housing 28 is contained in lighter shell 1 chamber.Magnetic force spare 13, moving contact 12, the cushion pad 14 of Swing type switch are housed in the switch housing 28.Magnetic force spare 13 is that its upper and lower side of permanent magnet is a magnetic pole, and it is installed in upper end, switch housing 28 chamber.Cushion pad 14 is made by sponge, and it is installed in lower ports place, switch housing 28 chamber.Moving contact 12 is balls, is that the ball that the ferromagnetic material steel is made is a steel ball.Lead 16 bottoms are pressed on switch housing 28 outer wall grooves and housing 1 inwall, and its lower end penetrates in switch housing 28 chambeies from the aperture 29 on switch housing 28 left sides, and it is exactly a static contact of Swing type switch.Sheet metal 27 peaks with heading penetrate in switch housing 28 chambeies from the aperture 30 on switch housing 28 the right, and it is exactly another static contact of Swing type switch.Lead 16 lower ends and sheet metal 27 peaks with heading promptly in twos the gap of static contact greater than ignition gap.Moving contact 12 is laterally gapped in switch housing 28, and it can move up and down in magnetic force spare 13 and cushion pad 14 restricted portions in switch housing 28 chambeies.Because magnetic force spare 13 is permanent magnets.Moving contact 12 is ferromagnets, and they are just by attracting magnetic interaction.Moving contact 12 under magneticaction with magnetic force spare 13 position contacting, be exactly the open position of moving contact 12 in its range of movement.Moving contact 12 just cuts off the gap of two static contacts when open position, it can contact with a static contact with another static contact gap less than ignition gap, it also can be all gapped respectively with two static contacts, Here it is moving contact 12 has two gaps with static contact, these two gaps and less than ignition gap.The position that moving contact 12 is pressed on the cushion pad 14 is exactly the closed position of moving contact at its range of movement.Moving contact 12 is when the closed position, and two static contacts and moving contact 12 are all gapped, these two gaps and greater than ignition gap.The open position of Swing type switch moving contact 12 relies on the sparking heading, and the closed position relies on the lighter bottom direction, and Here it is moving contact 12 closed positions are towards the situation of lighter bottom.
Moving contact 12 was at open position when Swing type switch was opened, the gap of moving contact 12 and static contact is less than ignition gap, the Swing type switch circuitous resistance is just less than the ignition gap circuitous resistance, at this moment if hitting, piezoelectric igniting mechanism 7 presses when giving birth to electricity, electric current does not just pass through the ignition gap circuit by the Swing type switch circuit, do not produce electric spark at ignition gap, lighter can not be operated and play combustion.When switch cuts out moving contact 12 just in the closed position at this moment moving contact and two static contact gaps and greater than ignition gap, and two static contact gaps are also greater than ignition gap, so, the resistance of Swing type switch circuit is greater than the ignition gap circuitous resistance, at this moment if hitting, piezoelectric igniting mechanism 7 presses when giving birth to electricity, electric current does not just pass through the ignition gap circuit by the Swing type switch circuit, and ignition gap will produce electric spark, and lighter just can be operated and play combustion.
Usually moving contact 12 stops at open position under magneticaction, if moving contact 12 is at open position and when making the closed position down, the gravity of moving contact is just opposite with suffered magnetic force direction, but at this moment moving contact 12 is bigger against the magnetic force that magnetic force spare 13 is subjected to, and moving contact 12 just still stops at open position.When moving contact 12 closed positions down downwards during the whipping lighter, be exactly that the lighter whipping stops at the moving contact closed position a kind of situation down that makes, moving contact 12 just overcomes magnetic force and moves to the closed position from open position under inertia and gravity effect, moving contact 12 arrives the closed position, effect of inertia closes Swing type switch but moving contact just stops at the closed position in the closed position from the little moving contact of magnetic force that magnetic force spare 13 far is subjected under the gravity effect after disappearing.After closing, Swing type switch make moving contact 12 closed positions not down the time when lighter, the gravity of moving contact is just not opposite with magnetic force direction, even commentaries on classics is identical with magnetic force direction, and moving contact 12 is that ball when motion resistance is little, and moving contact 12 just also can have under magneticaction and just is rolled into open position under the gravity effect from the closed position Swing type switch recovery is opened like this.Because we do the closed position of moving contact 12 towards lighter bottom, the closed position of lighter moving contact 12 head-up the time facilitates the lighter operation like this and plays combustion just down.
The front we by analysis Swing type switch when opening lighter can not operate and play combustion, lighter can be operated and play combustion when Swing type switch was closed.Usually Swing type switch is opened, and uses present embodiment lighter method commonly used to be, lighter is head-up got rid of Swing type switch to next just can close, and just can resemble then to operate lighter to be played combustion the common lighter.Lighter uses the general horizontal placement in back, moving contact 12 closed positions not down Swing type switch recover again to open.So it is very easily that the adult uses this lighter.When children play this lighter, so owing to close Swing type switch and play and not fire, even accidental getting rid of closed Swing type switch, but the sparking head makes Swing type switch recover to open again towards changing, so this is that a kind of children of preventing play the reliable lighter of combustion.
