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, bulge loop is provided with in the middle part of inside pipe casing, stack supercharging sheet, sealing ring and screen pack successively below bulge loop, finally seal with sealing gasket, become as a whole.The technical problem that existing structure exists: assembling trouble, sealing gasket easily come off, and reliability is poor.
Summary of the invention
In order to the assembling trouble, the sealing gasket 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, 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, the top of described sleeve pipe is provided with air admission hole, the bottom of described sleeve pipe is installed into pneumatic module, described air intake assembly comprises supercharging sheet, resilient sleeve, screen pack and trim ring, 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, the lower inner wall of described sleeve pipe is provided with ring-type draw-in groove, described filtration net cover is contained in the inner chamber of described resilient sleeve, described trim ring contacts the bottom at described screen pack.
Further, 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, as long as 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.
Further again, the outer wall of described resilient sleeve is provided with ring-type bulge loop, and described ring-type bulge loop is connected in described ring-type draw-in groove.
Further, the inwall of described sleeve pipe is provided with at least two-layer ring-type draw-in groove.
The lower end of described resilient sleeve is provided with tail cap.Tail cap can be had, also can not have.
The internal diameter top of the inner chamber of described resilient sleeve is little, the large formation step in bottom, under described screen pack is positioned at described step.This is a kind of preferred type of attachment, certainly, also can adopt other types of attachment.
The external diameter of described trim ring is more than or equal to the internal diameter of the lower lumen of described resilient sleeve.Wherein, described trim ring serves the effect of fixing screen pack, can effective location screen pack.Preferably, the external diameter of trim ring is more than or equal to the lower lumen internal diameter of described resilient sleeve, and form interference fit, such structure can make trim ring strut described resilient sleeve, further the firmness of strengthening resilient sleeve; Certainly, the external diameter of trim ring also can be less than the internal diameter of described resilient sleeve.
Technical conceive of the present utility model is: abandoned the mode of existing sealing gasket, directly adopts resilient sleeve to seal, simplifies the structure.
The beneficial effects of the utility model are mainly manifested in: easy to assembly, reliability is good.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
With reference to Fig. 1 ~ Fig. 6, a kind of lighter 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, described air-out needle 3 is provided with venthole 2, 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, described air intake assembly comprises supercharging sheet 6, resilient sleeve 10, screen pack 7 and trim ring 8, described resilient sleeve 10 is in hollow form, described supercharging sheet 6 is positioned at the upper end of resilient sleeve 10, described resilient sleeve 10 is sleeved on the lower lumen of described sleeve pipe 5, the lower inner wall of described sleeve pipe 5 is provided with ring-type draw-in groove 9, described screen pack 7 is sleeved on the inner chamber of described resilient sleeve 10, described trim ring 8 contacts the bottom at described screen pack 7.
Further, the external diameter of described resilient sleeve 10 is less than or equal to the lower inner diameter of described sleeve pipe 5.The resilient sleeve at this place, as long as 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.
Further again, the outer wall of described resilient sleeve 10 is provided with ring-type bulge loop, and described ring-type bulge loop is connected in described ring-type draw-in groove 9.
Further, the inwall of described sleeve pipe 5 is provided with at least two-layer ring-type draw-in groove 9.
The lower end of described resilient sleeve 10 is provided with tail cap.Tail cap can be had, also can not have.
The internal diameter top of 10 inner chambers of described resilient sleeve is little, the large formation step in bottom, under described screen pack 7 is positioned at described step.This is a kind of preferred type of attachment, certainly, also can adopt other types of attachment.
The external diameter of described trim ring 8 is more than or equal to the internal diameter of the lower lumen of described resilient sleeve 10.Wherein, described trim ring 8 serves the effect of fixing screen pack 9, can effective location screen pack.Preferably, the external diameter of trim ring 8 is more than or equal to the lower lumen internal diameter of described resilient sleeve 10, and form interference fit, such structure can make trim ring 8 strut described resilient sleeve 10, further the firmness of strengthening resilient sleeve 10; Certainly, the external diameter of trim ring 8 also can be less than the internal diameter of described resilient sleeve 10.
In the present embodiment, abandon the mode of existing sealing gasket, directly adopted resilient sleeve to seal, simplify the structure.
