Description
Technical field
The utility model belongs to a kind of lighter, especially a kind of combustion head.
Background technology
The air outlet valve of existing windproof lighter needs windproof combustion head is installed, existing combustion head, in the middle of fire collecting cover, turriform air-out needle is installed, the lower end of turriform air-out needle and sleeve upper end riveted joint, casing part is installed into pneumatic module, and described air intake assembly can adopt supercharging sheet, sealing ring, screen pack and the tail cap arranged from top to bottom.The technical problem that existing structure exists: 1, air-out needle and sleeve pipe assemble bother, 2, air intake assembly easily comes off, reliability is poor.
Summary of the invention
In order to the assembling trouble, the air intake assembly that overcome existing lighter combustion head easily come off, the deficiency that reliability is poor, the utility model provides a kind of easy to assembly, lighter combustion head that reliability is good.
The utility model solves the technical scheme that its technical problem adopts:
A kind of lighter combustion head, comprise fire collecting cover, escape pipe and air intake assembly, the top of described escape pipe is arranged in described fire collecting cover, the top of described escape pipe is provided with venthole, the middle part of described escape pipe is provided with air admission hole, and the bottom of described escape pipe is provided with the inner chamber installed for described air intake assembly, and described air intake assembly is arranged on described inner chamber, the lower end of described escape pipe is provided with interior flanging, and the lower end of described air intake assembly is pressed on described interior flanging.
Described interior flanging is horizontal or skewed.Can be 90 ° with the side of described sleeve pipe, can be also acute angle or obtuse angle with the side of described sleeve pipe, as long as can by air intake assembly positioning instant.
In this frame mode, interior flanging can locate described air intake assembly, and promote the reliability of air intake assembly, the normally overall ring-type of described interior ring, certainly, also can adopt other shapes such as ring-type profile of tooth.
Described air intake assembly comprises supercharging sheet, sealed elastic cover and screen pack, described supercharging sheet is positioned at the upper end of sealed elastic cover, described sealed elastic cover is sleeved on the inner chamber of described escape pipe, described filtration net cover is contained in the inner chamber of described sealed elastic cover, and the bottom of described sealed elastic cover is positioned on described flanging.
Described air intake assembly comprises supercharging sheet, sealing ring, screen pack and the tail cap arranged successively from top to bottom, and the bottom of described tail cap is positioned on described flanging.Certainly, the air intake assembly of other common form can also be adopted.
The external wall of upper portion of described escape pipe installs elastomer, and elastomeric outer wall is close to the inwall of described fire collecting cover.Certainly, air-out needle and fire collecting cover also can direct interference fit.
Technical conceive of the present utility model is: abandoned the locate mode of existing air intake assembly, and flanging in the lower end of sleeve pipe adopts, this interior flanging is located reliably to air intake assembly, enhances the reliability of connection.The processing of interior flanging adopts bordering tool conveniently to realize, and processes easy.Further, the sleeve pipe of original lighter and air-out needle are designed to one in escape pipe, more can simplify assembling.
The beneficial effects of the utility model are mainly manifested in: easy to assembly, reliability is good.

Fig. 1 is a kind of structural representation of lighter combustion head.
Fig. 2 is the structural representation of another kind of lighter combustion head.
Fig. 3 is the structural representation of another lighter combustion head.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
With reference to Fig. 1 ~ Fig. 3, a kind of lighter combustion head, comprise fire collecting cover 1, escape pipe 3 and air intake assembly, the top of described escape pipe 3 is arranged in described fire collecting cover 1, and the top of described escape pipe 3 is provided with venthole 2, and the middle part of described escape pipe 3 is provided with air admission hole 4, the bottom of described escape pipe 4 is provided with the inner chamber installed for described air intake assembly, described air intake assembly is arranged on described inner chamber, and the lower end of described escape pipe 3 is provided with interior flanging 5, and the lower end of described air intake assembly is pressed on described interior flanging 5.
Described interior flanging 5 is horizontal or skewed.Can be 90 ° with the side of described sleeve pipe, can be also acute angle or obtuse angle with the side of described sleeve pipe, as long as can by air intake assembly positioning instant.
In this frame mode, interior flanging 5 can locate described air intake assembly, and promote the reliability of air intake assembly, the normally overall ring-type of described interior ring, certainly, also can adopt other shapes such as ring-type profile of tooth.
Described air intake assembly comprises supercharging sheet 6, sealed elastic cover 8 and screen pack 7, described supercharging sheet 6 is positioned at the upper end of sealed elastic cover 7, described sealed elastic cover 7 is sleeved on the inner chamber of described escape pipe 3, described screen pack 7 is sleeved on the inner chamber of described sealed elastic cover 8, and the bottom of described sealed elastic cover 8 is positioned on described flanging 5.
Described air intake assembly comprises supercharging sheet 6, sealing ring 9, screen pack 7 and the tail cap 10 arranged successively from top to bottom, and the bottom of described tail cap 10 is positioned on described flanging 5.Certainly, the air intake assembly of other common form can also be adopted.
The external wall of upper portion of described escape pipe 3 installs elastomer 11, and the outer wall of described elastomer 11 is close to the inwall of described fire collecting cover 1.Certainly, air-out needle and fire collecting cover also can direct interference fit.
In the present embodiment, abandoned the locate mode of existing air intake assembly, flanging in the lower end of sleeve pipe adopts, this interior flanging is located reliably to air intake assembly, enhances the reliability of connection.The processing of interior flanging adopts bordering tool conveniently to realize, and processes easy.Further, the sleeve pipe of original lighter and air-out needle are designed to one in escape pipe, more can simplify assembling.
