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, inside pipe casing is installed into pneumatic module, described air intake assembly has two kinds of common forms, and a kind of structure is: the supercharging sheet arranged from top to bottom, sealing ring, screen pack and tail cap, described tail cap and sleeve interference grafting; Another kind of structure is: supercharging sheet, resilient sleeve and screen pack, described resilient sleeve is plugged in sleeve pipe.The technical problem that existing structure exists: air intake assembly easily comes off, and reliability is poor.
Summary of the invention
In order to the air intake assembly overcoming existing windproof combustion head easily comes off, the deficiency that reliability is poor, the utility model provides a kind of air intake assembly to be not easy the Novel igniter combustion head come off, reliability is good.
The utility model solves the technical scheme that its technical problem adopts:
A kind of Novel igniter combustion head, comprise fire collecting cover, air-out needle and sleeve pipe, air-out needle is installed at the middle part of described fire collecting cover, described air-out needle is provided with venthole, the lower end of described air-out needle is connected with the upper end of described sleeve pipe, and the top of described sleeve pipe is provided with air admission hole, and the lower lumen of described sleeve pipe is installed into pneumatic module, the inner chamber lower end of described sleeve pipe is provided with interior folding piece, and the lower end of described air intake assembly is positioned in described folding piece.
Preferably, described interior folding piece is interior ring; Certainly, also can be other versions, as long as can by the lower end positioning instant of air intake assembly;
In this frame mode, interior folding piece can locate the lower end of described air intake assembly, and the normally overall ring-type of described interior ring, certainly, also can adopt other shapes such as ring-type profile of tooth, segmented.
The interior knuckle of described interior folding piece, being preferably 90 °, certainly, also can be other angles, as long as location, the lower end of air intake assembly can be propped up.
Further, described air intake assembly comprises supercharging sheet, sealing ring, screen pack and the tail cap arranged from top to bottom, and the lower end of described tail cap is positioned on described ring.Wherein, described tail cap can with internal surface of sleeve pipe interference fit, also can be empty set.
Or: described air intake assembly comprises supercharging sheet, resilient sleeve and screen pack, described resilient sleeve is hollow form, described supercharging sheet is positioned at the upper end of resilient sleeve, described resilient sleeve is sleeved on the lower lumen of described sleeve pipe, described filtration net cover is contained in the inner chamber of described resilient sleeve, and the lower end of described resilient sleeve is positioned on described ring.
The external diameter of described resilient sleeve is less than or equal to the lower inner diameter of described sleeve pipe.The resilient sleeve at this place, fixes the position of resilient sleeve lower end by interior folding piece, make the upper end of resilient sleeve can upwards contact supercharging sheet, the upper-end contact face of supercharging sheet and resilient sleeve is sealing state; Certainly, the external diameter of resilient sleeve also can be selected slightly larger than the bottom diameter of described sleeve pipe.
Technical conceive of the present utility model is: the inner chamber lower end of sleeve pipe is provided with interior ring, and this interior ring can effectively support whole air intake assembly, ensures the reliability of air intake assembly assembling; And from the angle of processing technology, do not increase parts, during making, only need the lower end of sleeve pipe to carry out infolding operation, easy to operate.
The beneficial effects of the utility model are mainly manifested in: easy to assembly, air intake assembly is not easy to come off, reliability is good.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of Novel igniter combustion head.
Fig. 2 is the structural representation of another kind of Novel igniter combustion head.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
See figures.1.and.2, a kind of Novel igniter combustion head, comprise fire collecting cover 1, air-out needle 3 and sleeve pipe 5, air-out needle 3 is installed at the middle part of described fire collecting cover 1, and described air-out needle 3 is provided with venthole 2, and the lower end of described air-out needle 3 is connected with the upper end of described sleeve pipe 5, the top of described sleeve pipe 5 is provided with air admission hole 4, the bottom of described sleeve pipe 5 is installed into pneumatic module, and the inner chamber lower end of described sleeve pipe 5 is provided with interior folding piece 10, and the lower end of described air intake assembly is positioned in described folding piece 10.
Preferably, described interior folding piece 10 is interior ring; Certainly, also can be other versions, as long as can by the lower end positioning instant of air intake assembly;
In this frame mode, interior folding piece can locate the lower end of described air intake assembly, and the normally overall ring-type of described interior ring, certainly, also can adopt other shapes such as ring-type profile of tooth, segmented.
The interior knuckle of described interior folding piece 10, being preferably 90 °, certainly, also can be other angles, as long as location, the lower end of air intake assembly can be propped up.
Further, described air intake assembly comprises supercharging sheet 6, sealing ring 7, screen pack 8 and the tail cap 9 arranged from top to bottom, and the lower end of described tail cap 9 is positioned on described ring 10.Wherein, described tail cap 9 can with sleeve pipe 5 inwall interference fit, also can be empty set.
Or: described air intake assembly comprises supercharging sheet 6, resilient sleeve 11 and screen pack 8, described resilient sleeve 11 is in hollow form, described supercharging sheet 6 is positioned at the upper end of resilient sleeve 11, described resilient sleeve 11 is sleeved on the lower lumen of described sleeve pipe 5, described screen pack 8 is sleeved on the inner chamber of described resilient sleeve 11, and the lower end of described resilient sleeve 11 is positioned on described ring 10.
The external diameter of described resilient sleeve 11 is less than or equal to the lower inner diameter of described sleeve pipe 5.The resilient sleeve at this place, fixes the position of resilient sleeve lower end by interior folding piece, make the upper end of resilient sleeve can upwards contact supercharging sheet, the upper-end contact face of supercharging sheet and resilient sleeve is sealing state; Certainly, the external diameter of resilient sleeve also can be selected slightly larger than the bottom diameter of described sleeve pipe.
In the present embodiment, the inner chamber lower end of sleeve pipe 5 is provided with interior ring 10, this interior ring 10 can effectively support whole air intake assembly, ensures the reliability of air intake assembly assembling; And from the angle of processing technology, do not increase parts, during making, only need the lower end of sleeve pipe to carry out infolding operation, easy to operate.
