Abstract
The utility model provides a windproof combustion head of a lighter, which comprises a fire concentrating sleeve, an air outlet needle and a metal casing, wherein the air outlet needle is mounted at the middle part of the fire concentrating sleeve; the lower end of the air outlet needle is connected with the upper end of the metal casing; an air inlet component is mounted at the lower part of the metal casing, and comprises a supercharging sheet, a sealing ring, a filtering net and a sealing tail cap that are sequentially superposed from the top down; an insulation shielding sleeve is mounted outside the metal casing in a sleeving manner; the upper end of the insulation shielding sleeve is higher than the lower end of the fire concentrating sleeve; and the lower end of the insulation shielding sleeve is lower than the lower end of the metal casing. The windproof combustion head of the lighter is good in ignition reliability.
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, turriform air-out needle 3 is installed in the middle of fire collecting cover 1, the lower end of turriform air-out needle 3 and metal sleeve 9 upper end riveted joints are provided with bulge loop, following supercharging sheet 5, sealing ring 6 and the screen pack 7 of stacking successively of bulge loop in the middle part of metal sleeve 9 is inner, seal with sealing tail cap 8 at last, become as a whole.During work, the gas of lighter is successively by sealing tail cap 8, screen pack 7, sealing ring 6 and supercharging sheet 5, arrive the top of turriform air-out needle 3 and four holes by its top go out gas firing, also lack a necessary condition but burn, the top of Here it is metal sleeve 9 has a pair of symmetrical holes 4 of crossing, air enters the gas of inside cavity and bottom carrying and mixes crossing symmetrical holes 4 by this, arrives the top of turriform air-out needle 3 and four ventholes 2 by its top go out gas firing.
The technical problem that existing structure exists: metal sleeve 9 conducts electricity, and during igniting, easily electricity is introduced metal sleeve, causes loss of ignition.
Summary of the invention
For the easy failed deficiency of igniting that overcomes existing lighter combustion head, the utility model provides a kind of reliability of lighting a fire good lighter wind-prevention combustion head.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of lighter wind-prevention combustion head, comprise fire collecting cover, air-out needle and metal sleeve, air-out needle is installed at the middle part of described fire collecting cover, 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, described air intake assembly comprises supercharging sheet, sealing ring, screen pack and the sealing tail cap that stacks successively from top to bottom, described metal sleeve is set with the insulation shielding cover outward, the upper end of described insulation shielding cover is higher than the lower end of described fire collecting cover, and the lower end of described insulation shielding cover is lower than the lower end of described metal sleeve.
Described insulation shielding cover coats described metal sleeve, has played the effect of shielding, can effectively guarantee the igniting of air-out needle.
The beneficial effects of the utility model are mainly manifested in: the igniting reliability is good.
Description of drawings
Fig. 1 is the structural representation of existing combustion head;
Fig. 2 is the structural representation of lighter wind-prevention combustion head.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
with reference to Fig. 2, a kind of lighter wind-prevention combustion head, comprise fire collecting cover 1, air-out needle 3 and metal sleeve 9, air-out needle 3 is installed at the middle part of described fire collecting cover 1, 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 metal sleeve 9, the bottom of described metal sleeve 9 is installed into pneumatic module, described air intake assembly comprises the supercharging sheet 5 that stacks successively from top to bottom, sealing ring 6, screen pack 7 and sealing tail cap 8, the outer suit insulation shielding cover 10 of described metal sleeve 9, the upper end of described insulation shielding cover 10 is higher than the lower end of described fire collecting cover 1, the lower end of described insulation shielding cover 10 is lower than the lower end of described metal sleeve 9.
Described insulation shielding cover 10 coats described metal sleeve 9 get up, and has played the effect of shielding, can effectively guarantee the successful igniting of air-out needle.
