Description
Technical field
The present invention relates to a kind of lighter,, be meant the high-grade lighter of the replaceable fuel box of metal shell especially more specifically to a kind of lighter with replaceable fuel box.
Background technology
The structure of modern lighter remains fairly simple, the fuel gas that stores with liquid state be the lighter structure of fuel comprise liquid fuel gas storage with release control device, igniting (in fact be meant and produce spark) device, determine the burner apparatus (or also comprising its switching mechanism) of flare producing method etc.Lighter must include the liquefied gas as fuel holder of fuel supplying, so that provide flame or bright eruption after the burning.A kind of liquefied gas as fuel holder of routine has a relief valve that communicates with nozzle and one and adds air valve, be used for coming through this valve, in such a way refilling fuel, promptly when the fuel of lighter was used up, the user can refill fuel by gas filling bottle.One of them direction of development of lighter is to adopt the replaceable fuel box recently, replaces an empty fuel cassette with a fully loaded fuel cassette, and purpose is to make the lighter life-span be able to maximum prolongation.
A kind of lighter of replaceable fuel box is disclosed in Japanese documentation JP2001 one 12737A.In this scheme, fuel cassette and superstructure can freely change.But its fuel cassette must could be fixed by relative rotation between its special member with superstructure, and both will rotate relative to one another just removable by this specialized structure, when the refuelling box, also needs shell is pulled down fully.Therefore, its structure is comparatively complicated comparatively speaking.And, also must unload just dismantled and assembled fuel cassette of lower casing, it is not too convenient to use.
Disclose a kind of simple type lighter of replaceable gas container in Chinese patent literature cn2146664, in this scheme, fuel cassette (gas container) also can freely change with superstructure.But in its fuel cassette and the superstructure nozzle cooperate that the structure explanation that provides is promptly unclear to be difficult to carry out again, do not match with the commercial gas relief valve of routine, also caused this product also disclosed applicating adn implementing not till now in market.
The applicant discloses a kind of lighter of replaceable fuel box in an own Chinese patent application 02116399.5 of authorizing.In this scheme, fuel cassette and superstructure also can freely change, as long as the door closure of housing bottom is just opened and the fuel cassette of this case lighter can be taken out or be inserted in the housing, shut the door subsequently and just can finish the operation of refuelling box.So it is relatively simple for structure, it is comparatively convenient to operate.But could discharge gas because the gas release valve of inflation lighter all upwards pulls out valve, cost of manufacture is higher so patent can not adopt conventional gas release valve.The applicant has carried out a series of improvement to it again for this reason, has proposed a kind of lighter and replaceable fuel box of new construction.Disclosed Chinese patent Shen 200520127099.8, name is called " lighter of replaceable fuel box and replaceable fuel box thereof " and has done serial improvement on removable fuel cassette and lighter thereof, and both are used as the application's list of references in the lump.
Summary of the invention
The object of the invention provides a kind of lighter with replaceable fuel box, it is relatively simple for structure reliable, operation is also convenient, the leakage that is released fuel between can preventing from the fuel cassette to the nozzle, adopt commercially available conventional gas relief valve to be combined in the replaceable fuel box, thereby its cost of manufacture is lower.
To achieve these goals, the invention provides a kind of lighter of replaceable fuel box, comprising: one has a receptive cavity and a housing that makes described receptive cavity and extraneous opening of linking up; Be provided with gas nozzle in described case top, described nozzle is connected with the replaceable fuel box by a head protector, reaches one from the gas dispatch tube of head protector extension to described gas nozzle; One is bearing on the housing, is used to produce the ignition system towards the spark of this nozzle; A gas release lever is supported on the described replaceable fuel box with the pivot motion mode, this bar have actuating that matches with gas release valve on the described replaceable fuel box terminal and one drive end, when this driving end is depressed, this actuating is terminal to make progress the described gas release valve of lifting and discharges the fuel that is liquefied from described replaceable fuel box in the pivoting action mode, and the gas release lever also is connected with removably with described gas release valve; And a driving gas release lever drives the terminal mechanism that presses down, its characteristics are: described head protector is fixedly supported upon in the described housing, wherein said head protector has an inner chamber, settle the operating side of described gas release valve in the chamber with removably, be provided with seal between the inner chamber of head protector and the operating side of gas release valve, the operating side of head protector and gas release valve constitutes sealing movingly at gas release valve when described replaceable fuel box discharges burned liquefied gas.
The lighter of replaceable fuel box provided by the invention, replaceable fuel box and superstructure cooperate and the lighter internal structure on all done a large amount of improvement design on the door closure that when fuel cassette is changed, is mated with ining addition, the lighter structure of this form is more become rationally with reliable, operation simultaneously is also convenient, the leakage that is released fuel between can preventing from the fuel cassette to the nozzle, and can combine with the lighter outward appearance is good, the assembling of lighter is also very simple.
