Description
Technical field
The utility model belongs to self-filler.
Background technology
Gas filled device, is carbon dioxide, and the gases such as nitrogen are filled with in the container of splendid attire product, to replace the device of internal tank air.In actual life, a lot of things all need inflation, such as: all kinds of tires such as motor tire, electric vehicle tyre, bike tyre; Again such as: basketball, football etc. are all kinds of ball, etc.Gas filled device has become an indispensable part in daily life.But because current gas filled device is all an independently part substantially, some gas filled device is inconvenient to carry, such as the larger inflation mercury of those electricity consumptions; Some gas filled device troublesome poeration, such as the gas filled device of conventional Manual inflating.Little for bicycle, this class load space of battery-driven car, often need again mobile type, above-mentioned two kinds of gas filled devices use relatively inconvenient.And when tire flat, do not have gas filled device just can only, by the mode manually pushing away, even if there is gas filled device, is full of gas and not necessarily car can have been ridden up to maintenance station yet.Therefore, need portability on a kind of battery-driven car maybe can fix and prevent from filling quick-fried self-filler during for tire flat.
Summary of the invention
The utility model is not enough for prior art, provides a kind of and is fixed on battery-driven car, and prevent from filling quick-fried, saves power supply, the self-filler during for tire flat.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: self-filler, comprise supply gas cavity and exhaust cavity, in described exhaust cavity, be provided with fixed link and deflation hole, described cavity and the exhaust cavity of supplying gas isolated by a baffle plate, on described baffle plate, offer one number service hole, be provided with the circular cone that can seal one number service hole, described circular cone is connected with elastic parts, the other end of described elastic parts and described fixed link are connected and fixed, the described cavity of supplying gas offers the air taking port matching with cranked tire valve, the described cavity of supplying gas also offers through hole No. two, described No. two through holes connect air duct, the described air duct other end connects inflation pump, described inflation pump connects electric-conductor, on tire shelf, be also provided with brush, described brush connects No. two switches, described No. two switches connect storage battery.This device can be when tire continues gas leakage and during tire motion to automatic tyre air inflation, make tire continue to keep best air pressure, and prevent from filling quick-fried tire, power supply is saved in the inflation of sectional type.
In technique scheme, described circular cone surface is fixed with spongy layer.Reduce the friction between circular cone and baffle plate, extension fixture service life.
In technique scheme, described inflation pump is welded on tire wheel hub.Prevent that inflation pump from dropping, the practicality of intensifier.
In technique scheme, described brush is curved to be fixed on tire shelf.Facilitate brush to conduct electricity with contacting of electric-conductor.
The utility model compared with prior art, has following beneficial effect: the utility model can be fixed on battery-driven car, prevents that inflation pump and battery from dropping, the practicality of intensifier.This device can be when tire continues gas leakage and during tire motion to automatic tyre air inflation, make tire continue to keep best air pressure, and prevent from filling quick-fried tire, power supply is saved in the inflation of sectional type.Spongy layer can reduce the friction between circular cone and baffle plate, extension fixture service life.Brush is curved to be fixed on tire shelf, facilitates brush to conduct electricity with contacting of electric-conductor.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram.
Fig. 2 is brush and electric-conductor distribution schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail: referring to Fig. 1 ~ Fig. 2, self-filler, comprise supply gas cavity 1 and exhaust cavity 2, be provided with fixed link 3 and deflation hole 4 in described exhaust cavity 2, deflation hole 4 is for discharging unnecessary gas.The described cavity 1 of supplying gas by 5 isolation of a baffle plate, offers one number service hole 6 on described baffle plate 5 with exhaust cavity 2, is provided with the circular cone 7 that can seal one number service hole 6, and unnecessary gas is pushed circular cone 7 open, from deflation hole 4, discharges.
Described circular cone 7 is connected with elastic parts 8, and elastic parts 8 can be spring.The other end of described elastic parts 8 and described fixed link 3 are connected and fixed.After unnecessary gas is discharged, elastic parts 8 continues to withstand one number service hole 6 circular cone 7, prevents that the gas in tire is all exposed to light accidentally.
Circular cone 7 surfaces are one deck spongy layer fixedly.Spongy layer can reduce the friction between circular cone 7 and baffle plate 5, extension fixture service life.
The described cavity 1 of supplying gas offers the air taking port 9 matching with cranked tire valve, and air taking port 9 can be offered some screw threads, matches with cranked tire valve, can directly this device be screwed into cranked tire valve and fix during use.The described cavity 1 of supplying gas also offers through hole 10 No. two, described No. two through holes 10 connect air duct 11, described air duct 11 other ends connect inflation pump 12, described inflation pump 12 connects electric-conductor 111, on tire shelf, be also provided with brush 112, described brush 112 connects No. two switches 114, and described No. two switches 114 connect storage battery.After opening No. two switches 114, only, when electric-conductor 111 is connected with brush 112, storage battery can be to inflation pump 12 power supplies, namely only when tire motion, storage battery can be to inflation pump 12 power supplies, saved the consumption of power supply, need not time, close switch 114 No. two.
Above-mentioned inflation pump 12 is welded on tire wheel hub.Prevent that inflation pump 12 from dropping, the practicality of intensifier.
Described brush 112 is curved to be fixed on tire shelf.Facilitate brush 112 to conduct electricity with contacting of electric-conductor 111.
When tire flat, open switch 114 No. two, the electricity of storage battery leads to brush 112, in the motion process of tire, what brush 112 was interrupted contacts conduction power supply to inflation pump 12 with electric-conductor 111, and inflation pump 12 is inflated tire, gas enters in the chamber of supplying gas 1 by air duct 11, then from air taking port 9, enter into tire, so continue tire to inflate, make tire continue to keep best air pressure.Gas enters into tire always, will certainly cause filling of tire quick-fried, and this device can prevent that filling of tire is quick-fried, and unnecessary gas can back down circular cone 7, and from flow out in one number service hole 6, from deflation hole 4, discharges.And, to discharge after unnecessary gas, elastic parts 8 can continue to withstand one number service hole 6 by circular cone 7, prevents that gas is all exposed to light accidentally.Therefore, tire can continue to remain on best air pressure, until car reaches maintenance station, keeps in repair.
