Summary of the invention
In order to overcome the deficiency that between the turriform air-out needle of existing lighter combustion head and sleeve pipe, connection reliability is poor, the lighter combustion head that the utility model provides a kind of connection reliability 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, the bottom of described fire collecting cover is sleeved on the external wall of upper portion of described sleeve pipe, the top of described sleeve pipe is provided with overhanging ring, described overhanging ring is plugged on the lower lumen of described air-out needle, and the lower end of described air-out needle is provided with the interior flanging extended internally.
In this programme, described interior flanging stops between air-out needle and sleeve pipe and mutually departs from, described interior flanging selects the structure of a whole circle usually, also flanging in a section can be selected, the situation such as flanging in flanging or three sections in two sections, as long as this interior flanging can play the effect strengthening connecting, prevent from causing loosening between air-out needle and sleeve pipe because expanding with heat and contract with cold or vibrating.
Further, conflict at the middle part outer wall of described sleeve pipe in the lower end of described interior flanging.
The lower lumen of described air-out needle is provided with positioning step, and described overhanging ring is conflicted on described positioning step.
Further, the external wall of upper portion of described sleeve pipe has annular groove, installs elastomer in described annular groove, and described elastomer is conflicted in the lower inner wall of described fire collecting cover.
The lower inner wall of described fire collecting cover is provided with locating table, and the bottom of described locating table and described annular groove maintains an equal level, and described elastomer is positioned at the bottom of described locating table and described annular groove simultaneously.
Described elastomer is 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, and in adopting, the connected mode of flanging, makes connection reliability between turriform air-out needle and sleeve pipe very high.
By hard connecting mode existing between sleeve pipe and fire collecting cover, 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.
The beneficial effects of the utility model are mainly manifested in: connection reliability is good, reduce costs.
Accompanying drawing explanation
Fig. 1 is the structural representation of 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 top of described sleeve pipe 5 is provided with overhanging ring, described overhanging ring is plugged on the lower lumen of described air-out needle 3, the lower end of described air-out needle 3 is provided with the interior flanging 11 extended internally.
In this programme, described interior flanging stops between air-out needle and sleeve pipe and mutually departs from, and described interior flanging 11 selects the structure of a whole circle usually, also can select flanging in a section, the situation such as flanging in flanging or three sections in two sections,
As long as this interior flanging can play the effect strengthening connecting, prevent from causing loosening between air-out needle and sleeve pipe because expanding with heat and contract with cold or vibrating.
Further, conflict at the middle part outer wall of described sleeve pipe 5 in the lower end of described interior flanging 11.
The lower lumen of described air-out needle 3 is provided with positioning step, and described overhanging ring is conflicted on described positioning step.
Further, the external wall of upper portion of described sleeve pipe 5 has annular groove, and install elastomer 10 in described annular groove, described elastomer 10 is conflicted in the lower inner wall of described fire collecting cover 1.
