The windproof combustion head of the lighter, provided by the utility model, has a simplified structure, is convenient for assembling, has high processing efficiency, and is low in processing cost.
Description
Technical field
The utility model belongs to a kind of lighter, especially a kind of combustion head.
Background technology
Need to install windproof combustion head on the air outlet valve of existing windproof lighter, existing combustion head, with reference to Fig. 1, be provided with air-out needle 2 in the middle of the fire collecting cover 1, the lower end of air-out needle 2 is connected with metal sleeve 3, the external wall of upper portion of described metal sleeve 3 is connected with the inner chamber bottom of fire collecting cover, and described metal sleeve 3 overcoats set a nut 4, and described positioning screw cap 4 is connected with the external screw thread of the external wall of upper portion of described metal sleeve 3;
The technical problem that existing structure exists: the connected mode of metal sleeve and fire collecting cover, complex structure, during assembling, at first need the external wall of upper portion of described metal sleeve 3 is connected with the inner chamber bottom of fire collecting cover 1, refill and join positioning screw cap 4,, waste time and energy during assembling because metal sleeve 3, fire collecting cover 1 and positioning screw cap 4 all belong to finding, working (machining) efficiency is lower, has improved processing cost.
Summary of the invention
For the complex structure that overcomes existing lighter combustion head, the deficiency that assembling is wasted time and energy, working (machining) efficiency is lower, processing cost is high, the utility model provides a kind of simplified structure, be convenient to assemble, working (machining) efficiency height, the windproof combustion head of lighter that cuts down finished cost.
The technical scheme that its technical problem that solves the utility model adopts is:
The windproof combustion head of a kind of lighter, comprise fire collecting cover, air-out needle and metal sleeve, the middle part of described fire collecting cover sets out air tube, the lower end of described air-out needle is connected with the upper end of described metal sleeve, the bottom of described metal sleeve is installed into pneumatic module, the inner chamber bottom of described fire collecting cover is stretched on the outer wall top of described metal sleeve, and the inner chamber interference fit of the top of described metal sleeve outer wall and described fire collecting cover.
Further, the inner chamber bottom of described fire collecting cover is provided with first step, and the top of described metal sleeve outer wall is provided with second step, and described second step is positioned on the first step.
Or the middle part of described metal sleeve outer wall is provided with positioning step, and the lower end of described fire collecting cover is positioned on the described positioning step.
The design of above-mentioned step, mainly be for more reliable after the feasible assembling, technology general knowledge in conjunction with those of ordinary skill in the art, also can adopt the mode of other interference fit, interference fit of the present utility model is meant: the external diameter of the outer wall place cross section of described metal sleeve is bigger slightly than the internal diameter of the inner chamber of described fire collecting cover, be the inner chamber that metal sleeve is extruded to fire collecting cover, form a fixed connection.
Further, described air intake assembly comprises supercharging sheet, packing ring, screen pack, sealing ring and the sealing tail cap that sets gradually from top to bottom.
The beneficial effects of the utility model mainly show: simplified structure, be convenient to assembling, working (machining) efficiency height, cut down finished cost.
Description of drawings
Fig. 1 is the structural representation of existing combustion head;
Fig. 2 is the structural representation of the windproof combustion head of a kind of lighter;
Fig. 3 is the structural representation of the windproof combustion head of another kind of lighter.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 2 and Fig. 3, the windproof combustion head of a kind of lighter, comprise fire collecting cover 1, air-out needle 2 and metal sleeve 3, the middle part of described fire collecting cover 1 sets out air tube 2, the lower end of described air-out needle 2 is connected with the upper end of described metal sleeve 3, the bottom of described metal sleeve 3 is installed into pneumatic module, and the inner chamber bottom of described fire collecting cover 1 is stretched on the outer wall top of described metal sleeve 3, and the inner chamber interference fit of the top of described metal sleeve 3 outer walls and described fire collecting cover 1.
Further, the inner chamber bottom of described fire collecting cover 1 is provided with first step, and the top of described metal sleeve 3 outer walls is provided with second step, and described second step is positioned on the first step.
Or the middle part of described metal sleeve 3 is provided with positioning step, and the lower end of described fire collecting cover 1 is positioned on the described positioning step.
The design of above-mentioned step, mainly be for more reliable after the feasible assembling, technology general knowledge in conjunction with those of ordinary skill in the art, also can adopt the mode of other interference fit, interference fit of the present utility model is meant: the external diameter of the outer wall place cross section of described metal sleeve is bigger slightly than the internal diameter of the inner chamber of described fire collecting cover, be the inner chamber that metal sleeve is extruded to fire collecting cover, form a fixed connection.Assembled is as long as be expressed to locating sleeve in the fire collecting cover by external force.
Further, described air intake assembly comprises supercharging sheet 5, packing ring 6, screen pack 7, sealing ring 8 and the sealing tail cap 9 that sets gradually from top to bottom.
The course of work of present embodiment: the gas of lighter is successively by sealing tail cap 9, sealing ring 8, screen pack 7, packing ring 6 and supercharging sheet 5, arrive the venthole at the top of air-out needle 2, also lack a necessary condition but burn, the top of Here it is metal sleeve 3 has a pair of symmetrical holes 10(that crosses and also can just open one and cross symmetrical holes 10), air enters the gas of inside cavity and bottom carrying and mixes crossing symmetrical holes 10 by this, and the venthole that arrives the top of air-out needle 2 goes out gas firing.
With respect to prior art, simplified structure, be convenient to assembling, working (machining) efficiency height, cut down finished cost.
