Abstract
The invention relates to an aerating device, in particular to an aerating device of a cigarette lighter, which comprises a pressing spring, a seal ring, a charging connector and a gas nozzle base. The charging connector is a cylindrical component whose cylindrical surface is provided with a ring-shaped convex shoulder, and more than one groove is arranged along axial direction on the cylindrical surface on the inlet side of the charging connector convex shoulder to form a charging channel. The charging connector of the invention forms a charging channel through arranging more than one groove on the cylindrical surface on the inlet side of the charging connector, therefore plastic injection molding can not adopt the matched die way, and the cylindrical surface of the charging connector is not provided with a matched die line, which can favorably seal, thereby achieving the purposes of convenient manufacture, excellent seal property and low material costs.
Description
Technical field
The present invention relates to a kind of inflator, specifically is exactly lighter aeration device.
Background technique
Lighter can be divided into two classes from the words of classifying working life at present: inflatable lighter or disposable lighter, disposable lighter are except that individual part, and most of plastic components that adopts belongs to low grade products, and is cheap; Inflatable lighter adopts metal shell usually, class is higher, fashion youth and successful personage like using, particularly disposable lighter is just abandoned after using, not only waste material but also not environmental protection, therefore the disposable lighter of import is imposed the tariff of the great number more much higher abroad, so existing lighter particularly is provided with inflatable apparatus on Chu Kou the lighter than inflatable lighter.
Present inflator constitutes holddown spring by charging air inlet, seal ring helical spring usually, charging air inlet is the cylindrical member that cylinder is provided with annular convex shoulder, charging air inlet is provided with dark blind hole vertically, seal ring is inserted in to convex shoulder from the blind hole opening, and the cylinder of close seal ring is provided with the cross-drilled hole that is communicated with blind hole and forms filling channel.Holddown spring one end is enclosed within on the other end of charging air inlet.With the gas tank mouth charging air inlet is headed into cross-drilled hole to be under the seal ring be communicated with the gas tank inner chamber in gas tank during inflation and inflate, after finishing, inflation extracts gas tank, charging air inlet outwards resets under the pressure of opposite side holddown spring promotes cross-drilled hole is got back on the seal ring, and seal ring forms sealing under the clamping of convex shoulder and gas tank bottom.Traditional charging air inlet all is with copper material car system.Processing charges and cost of material are higher, and along with soaring of recent copper material price, the cost of inflator is higher.Some producers begin to adopt plastic injection-moulded mode to make charging air inlet for this reason, but owing to have the cross-drilled hole that is communicated with blind hole on the cylinder, can only adopt the mode of matched moulds when plastic injection-moulded, so must have assembly line, cause poorly sealed and leak gas.
Summary of the invention
The objective of the invention is to provides a kind of easy to make, good seal performance, the inflator that the cost of material is low for overcoming the deficiencies in the prior art.
For achieving the above object, technical solution provided by the invention is as follows: a kind of inflator, comprise holddown spring, seal ring and charging air inlet and valve seat, described charging air inlet is the cylindrical member that cylinder is provided with the ring-type convex shoulder, described valve seat is that bottom centre is provided with and the charging air inlet tubbiness member of through hole movingly, the groove that the cylinder upper edge of described charging air inlet convex shoulder air inlet one side is axially arranged with one or more constitutes filling channel, described seal ring comprises exterior seal ring and inner seal ring, insert the valve seat inner chamber from valve seat bottom centre through hole behind the sheathed upward inner seal ring on the cylinder of described charging air inlet convex shoulder air inlet one side, described exterior seal ring is set in charging air inlet and inserts on the cylinder of part in the valve seat inner chamber, described holddown spring is a helical spring, and the lower end is connected on the other end of charging air inlet and constitutes inflatable component.
As the further setting of the present invention: described charging air inlet is provided with 2～5 grooves, evenly distributes along circumference.
Further be provided with as of the present invention: described inflator also is provided with outer sleeve, described outer sleeve length and inflatable component match, the center is provided with the charging air inlet cavity volume that shoulder hole that shape and inflatable component match constitutes, outer sleeve charging air inlet cavity volume top is provided with the air outlet hole of diameter less than holddown spring, and the upper end of described holddown spring is against charging air inlet cavity volume top.
The present invention compared with prior art teaches beneficial effect: because charging air inlet of the present invention is to constitute filling channel by the groove that is axially arranged with one or more in the cylinder upper edge, can not adopt the mode of matched moulds when therefore plastic injection-moulded, do not have assembly line on the charging air inlet cylinder, can seal well.Easy to make, good seal performance, the purpose that the cost of material is low have been reached.
The invention will be further described below in conjunction with accompanying drawing, and provide embodiment.
