Description

Lighter combustion head
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 comprises fire collecting cover, sleeve pipe, turriform air-out needle and air intake assembly, in the middle of described fire collecting cover, turriform air-out needle is installed, the lower end of turriform air-out needle and sleeve upper end riveted joint, the bottom of described fire collecting cover is sleeved on the external wall of upper portion of described sleeve pipe, and inside pipe casing is installed into pneumatic module.The technical problem that existing structure exists: 1, the bottom of described fire collecting cover and the top of described sleeve pipe are Hard link, and connection reliability is poor; 2, can not carry out dismounting refitting after assembling, cannot carry out secondary utilization to parts, production cost is high.
Summary of the invention
In order to overcome the deficiency that between the fire collecting cover of existing lighter combustion head and sleeve pipe, connection reliability is poor, cost is high, the utility model provides the lighter combustion head that a kind of connection reliability is good, reduce costs.
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, the bottom of described fire collecting cover is sleeved on the external wall of upper portion of described sleeve pipe, the external wall of upper portion of described sleeve pipe has annular groove, install the first elastomer in described annular groove, described first elastomer is conflicted in the lower inner wall of described fire collecting cover.
Further, the inner ring of the upper end of described sleeve pipe is provided with step, and the lower end of described air-out needle is positioned on described step.
Further again, the middle part outer wall of described air-out needle is provided with outer flange collar, arranges the second elastomer between the upper end of described sleeve pipe and described outer flange collar.
Further, described air-out needle and described sleeve pipe are in one.This is a kind of mode that can adopt, and certainly, it is conventional version that air-out needle and sleeve pipe separate.
Described first elastomer and the second elastomer are elastic ring; Such as adopt conventional O type circle, certainly, also can adopt other closed elastic body, or semiclosed elastomer etc.
Technical conceive of the present utility model is: in this programme, by existing hard connecting mode, changes to and is flexible coupling by elastomeric, improve the reliability of connection, and avoiding is the situation of external vibration, also can not produce loosening; Moreover, after adopting this elastomeric connected mode, mutually can dismantle between fire collecting cover and sleeve pipe, and carry out secondary utilization, reduce cost.
The beneficial effects of the utility model are mainly manifested in: connection reliability is good, reduce costs.
Accompanying drawing explanation
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.
Fig. 4 is again 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, 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, the bottom of described fire collecting cover 1 is sleeved on the external wall of upper portion of described sleeve pipe 5, the external wall of upper portion of described sleeve pipe 5 has annular groove, in described annular groove, the first elastomer 10 is installed, described first elastomer 10 is conflicted in the lower inner wall of described fire collecting cover 1.
Further, the inner ring of the upper end of described sleeve pipe 5 is provided with step, and the lower end of described air-out needle 3 is positioned on described step.
Further again, the middle part outer wall of described air-out needle 3 is provided with outer flange collar, arranges the second elastomer 11 between the upper end of described sleeve pipe 5 and described outer flange collar.
Further, described air-out needle 3 and described sleeve pipe 5 are in one.This is a kind of mode that can adopt, and certainly, it is conventional version that air-out needle and sleeve pipe separate.
Described first elastomer and the second elastomer are elastic ring; Such as adopt conventional O type circle, certainly, also can adopt other closed elastic body, or semiclosed elastomer etc.
Described air intake assembly comprises supercharging sheet 6, resilient sleeve 8, screen pack 7 and fixed cover 9, described supercharging sheet 6 be positioned at the upper end of resilient sleeve 10, described resilient sleeve 10 is sleeved on the lower lumen of described sleeve pipe 5, described screen pack 7 is sleeved on the inner chamber of described resilient sleeve 8, the bottom of described resilient sleeve 8 is positioned on described fixed cover 9, and described fixed cover 9 is fixedly connected with the bottom of described sleeve pipe.Certainly, the air intake assembly of other common form can also be adopted.
In the present embodiment, by existing hard connecting mode, change to and be flexible coupling by elastomeric, improve the reliability of connection, avoiding is the situation of external vibration, also can not produce loosening; Moreover, after adopting this elastomeric connected mode, mutually can dismantle between fire collecting cover and sleeve pipe, and carry out secondary utilization, reduce cost.
