Description
Technical field
The utility model belongs to a kind of lighter, especially a kind of lighter combustion head.
Background technology
It needs that windproof combustion head, existing combustion head, the installation of porcelain cup centre are installed on the air outlet valve of existing windproof lighter
Outlet portion, the outlet portion are equipped with venthole, and the lower end in outlet portion connect with sleeve upper end, the middle part of described sleeve pipe equipped with into
Air intake assembly is installed in the lower part of stomata, casing, and the air intake assembly includes the constrictor arranged from top to bottom, tail cap and strainer
Piece.
Grafting between the lower end and casing in outlet portion, interference fit, which is realized, between the two positions；Outlet portion is with casing in heat
In the case of swollen shrinkage, it is easy to loosen between the two, connection reliability is poor.
Invention content
In order to overcome the shortcomings of that the connection reliability between the outlet portion and casing of existing lighter combustion head is poor, this
The preferable lighter combustion head of connection reliability between a kind of outlet portion of utility model offer and casing.
Technical solution adopted by the utility model to solve its technical problems is：
A kind of lighter combustion head, including porcelain cup, outlet portion and casing, installation outlet portion among the porcelain cup, it is described go out
Gas portion is equipped with venthole, and the middle part of described sleeve pipe is equipped with air admission hole, and air intake assembly is installed in the lower part of casing, the outlet portion
Lower part plugged and fixed continuously becomes in the upper inside wall of described sleeve pipe with the outer diameter in the outlet portion of the junction of casing from top to bottom
Greatly, bigger than the internal diameter of described sleeve pipe with the maximum outside diameter in the outlet portion of the junction of casing.
Further, equal with the upper inner diameter of casing with the minimum outer diameter in the outlet portion of the junction of casing.At this point, with set
The minimum outer diameter in the outlet portion of the junction of pipe is bigger than the upper inner diameter of described sleeve pipe.
Further, continuously become larger from top to bottom with the internal diameter of the casing of outlet portion junction.The shape and outlet of casing
Portion is adapted to, and further improves connection reliability.
Further, the conduct piece interference is plugged on porcelain cup external wall of upper portion.
Flame is set between the conduct piece and porcelain cup top surface and becomes color chips.
The beneficial effects of the utility model are mainly manifested in：With the outer diameter in the outlet portion of the junction of casing on to
Continuously become larger down, enhances the fastness of plugged and fixed；Even if expanding with heat and contract with cold there are larger, the stabilization of connection will not be influenced
Property, improve the reliability connected between outlet portion and casing.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of lighter combustion head.
Fig. 2 is the structural schematic diagram of another lighter combustion head.
Specific implementation mode
The utility model is further described below in conjunction with the accompanying drawings.
Referring to Figures 1 and 2, a kind of lighter combustion head, including porcelain cup 5, outlet portion 1 and casing 2, among the porcelain cup 5
Outlet portion 1 is installed, the outlet portion 1 is equipped with venthole 1-4, and the middle part of described sleeve pipe 2 is equipped with air admission hole 2-2, under casing 2
Air intake assembly is installed in portion, and the lower part plugged and fixed in the outlet portion 1 is in the upper inside wall of described sleeve pipe 2, the junction with casing
The outer diameter of outlet portion 1-2 continuously become larger from top to bottom, the maximum outside diameter with the outlet portion 1-2 of the junction of casing is than the set
The internal diameter of pipe 2 is big.
Further, equal with the upper inner diameter of casing 2 with the minimum outer diameter of the outlet portion 1-2 of the junction of casing.At this point,
It is bigger than the upper inner diameter of described sleeve pipe with the minimum outer diameter in the outlet portion of the junction of casing.
Further, continuously become larger from top to bottom with the internal diameter of the casing 2-1 of outlet portion junction.The shape of casing 2 with
Outlet portion 1 is adapted to, and further improves connection reliability.
4 interference of the conduct piece is plugged on 5 external wall of upper portion of porcelain cup.
Flame is set between 5 top surface of the conduct piece 4 and porcelain cup and becomes color chips 3.
The middle part in the outlet portion 1 is equipped with main venthole 1-3, is equipped with for auxiliary between the outlet portion 1 and supporting rack 10
The auxiliary venthole 1-1 of igniting, the upper end in the outlet portion is helped to be equipped with gas gathering ring, the gas gathering ring is equipped with upper venthole, institute
Auxiliary venthole is stated to be connected to the upper venthole.
The air intake assembly includes constrictor 6, tail cap 8 and filtering net plate 7, and 2 inner wall of described sleeve pipe is provided with venthole, the limit
The top surface of flow 6 abuts against on venthole, and the bottom surface of the constrictor 6 connects with the tail cap 8, and the filtering net plate 7 is located at institute
The inner cavity of tail cap 8 is stated, the aperture of the metering hole of the constrictor is less than the aperture of the venthole.8 sleeve of the tail cap
It inside stretches section 2-3 positioning or described sleeve pipe bottom mounting-fixing base 9, the tail cap 8 is located in the fixed seat 9.
The scheme of the present embodiment has abandoned the form between existing air-out needle and casing, the institute with the junction of casing
The outer diameter for stating outlet portion continuously becomes larger from top to bottom, enhances the fastness of plugged and fixed；Even if expanding with heat and contract with cold there are larger,
The stability for not interfering with connection improves the reliability connected between outlet portion and casing.
