Abstract

A lighter is composed of shell, middle sleeve, gas tube, manually pressed wheel unit, lower valve, valve (6), pressure reducing piece, upper pressure reducing piece and paressure stabilizing valve. The combustible gas flows through lower valve, cavity, gas channel, upper cavity to automatically open valve (6), presure reducing piece, shunt chamber, upper pressure reducing piece and pressure stabilizing valve to output, where it burns. Its advantages are quantitative burning of gas and high safety as use of quard on lighter top.

Description

Lighter

The present invention relates to a kind of lighter, the simple type plastic cement lighter of particularly carrying.

Widely used on the market at present plastic cement lighter lacks safety, is struck sparks by child easily, and in addition, the user will gas valve with hand when striking sparks during use, can not timing automaticly stop working.

The object of the present invention is to provide the timing automatic flame-out lighter of a kind of energy.

The present invention realizes like this, a kind of lighter promptly is provided, comprise the housing that constitutes lighter profile and its inner part supporting mass, the middle cover of hollow is inserted and secured on the precalculated position of housing, be provided with the hand wheel assembly that is used to strike sparks in the middle cover, the cover lower end was provided with at least two air valves that can form the rationing combustible gas during the tracheae of supply combustible gas was fixed on the combustible gas gas circuit between electric pipe and hand wheel assembly.

This lighter can also comprise the protective cover that is located at the top, covers the hand wheel.

The invention has the advantages that, by on the combustible gas supply channel of lighter, adopt plural air valve structure, making the combustible gas of each supply is quantitative combustible gas, thereby realizes timing automatic flame-out purpose, in addition, add a protective cover at the lighter top, cover the hand wheel, just prevented the possibility that the hand wheel is struck sparks by false touch fully, ensured transportation and carried process safe.

Describe embodiments of the invention with reference to the accompanying drawings in detail, among the figure,

Fig. 1 is the structural representation of timing automatic flame-out lighter of the present invention;

Fig. 2 is the comparative descriptions figure of single air valve lighter and many air valves of the present invention lighter;

Fig. 3 is the structural representation that includes protective roof structure of the present invention.

Consult Fig. 1, timing automatic flame-out lighter of the present invention includes housing 11, middle cover 12, tracheae 13, hand wheel assembly 14, axle sleeve 15, particularly, also include sliding sleeve 1, lower valve 2, cavity 3, air drain 4, upper cavity 5, valve 6, decompression sheet 7, diffluence room 8, on reduce pressure sheet 9, pressure maintaining valve 10.Wherein, housing 11 forms the shell of lighter and the supporter of parts such as skeleton and middle cover 12, the precalculated positions that middle cover 12 inserted and be fixed on housing 11, middle cover 12 is shell constructions of hollow, hollow space is waney cylindrical cavity, the cavity of its upper end is used to install pressure maintaining valve 10 and axle sleeve 15, hand wheel assembly 14 is installed in the axle sleeve 15, be used for igniting, the lower end of middle cover has snapped in tracheae 13, with sliding sleeve 1, lower valve 2, valve 6, decompression sheet 7, during being installed in, last decompression sheet 9 in cover 12 and the tracheae 13, formed cavity 3, air drain 4, upper cavity 5, diffluence room 8, each parts and each position, groove chamber indicate in the drawings.

The course of work of the present invention is as follows: when the hand wheel sparking of rotating, flint promotes downwards, pressing promotion lower valve 2 downwards by sliding sleeve 1 opens, the fuel gas of pressure is injected in two air drains 4 by both sides along direction shown in the arrow by cavity 3 quantitatively, and process air drain 4 enters in the upper cavity 5, because the automatic Open valve 6 of pressure of this gas, through decompression sheet 7, directly go in the diffluence room 8, again by last decompression sheet 9, automatically by the air pressure opened pressure maintaining valve 10 of this gas, light to top outlet, the flame of lighter takes fire.When forcing down in certain pressure in the fuel gas, each valve of 10 is closed automatically from valve 6 to pressure maintaining valve, cuts off the fuel gas supply, thereby makes the rapid auto extinguishing of flame.

Consult Fig. 2, Fig. 2 is the functional status key diagram relatively of the lighter of single air valve and many air valves, transverse axis is burning time, in second, the longitudinal axis is a flame height, in centimetre, broken line 1 is combustion efficiency and the rear situation with lighter of two or more air-valve devices, broken line 2 is corresponding situations of the lighter of single air valve, can know among the figure and find out, the flame height after the lighter of many air valves (two or more) device is lighted is higher, in the time of nearly two seconds, auto extinguishing does not stay any rears, and the lighter of single air valve flame height after lighting lowers rapidly, and leave long rear, the just flame-out danger in residual about one second of rear shown in the figure, therefore, many air valves designs of the present invention are just much superior.

Consult Fig. 3, Fig. 3 is the structure key diagram that includes protective roof structure of the present invention, the structure of the part on the left side has given explanation among this figure in Fig. 1, here no longer repeat, outside Fig. 1 parts, also set up protective cover 17 especially, be located at the top, and pellet shot from a slingshot location lock 18, windshield 19, reinforcement 20, add air valve 21, like this, after having additional shelter-clad 17, protective cover 17 can cover hand wheel, avoided fully in transportation or carry in produce the possibility of false touch sparking, particularly, also adopt elastic pellet shot from a slingshot location lock, be used to make protective cover 17 safety and firmnesses, can be stabilized in two positions that cover and open fully.The position that illustrated protective cover is opened is away from flame, and the flame of lighter can not be burned to protective cover, even the protective cover of plastic cement does not have problem yet, can not run into by flame.

The place has set up metal windshield 19 in the other flame ignition of hand wheel, offers two big air-vents in the both sides of cover, and making has enough air-breathings, and rapid heat dissipation.

Reinforcement is set up in bottom at the inner chamber of housing, and reinforcement 20 is upwards holded up along the middle part from the bottom, has strengthened the structural strength of housing on the one hand, lowers in addition in the fuel gas and presses, and makes the function of safe in utilization and stable fire.

Set up in the bottom inside of housing and to add air valve 21, flammable liquid gasification inside can attach new flammable liquid gasification again after finishing, to be fit to the environmental requirement of country variant.
