Abstract
The utility model relates to an electric double-air cylinder tire inflator. A motor is arranged in a casing. Two pistons driven by a variable speed driving mechanism do the reciprocating motion in two air cylinders. After air in the air cylinder is compressed, the compressed air is inflated into a vehicle tire through an inflation tube. The utility model also comprises two piston components, a non-return air valve component, and an elastic sealing component for avoiding the air leakage during air inflation. Because the opposite eccentric degree of two eccentric shafts in the variable speed driving mechanism is 180 DEG, when one piston moves forwards for compressing air in the air cylinder, the other piston moves backwards and air is suck into the air cylinder. The utility model has the advantages of high work efficiency, low cost and portability.

The purpose of this utility model provides the electric inflater of two cylinders of a kind of employing, and it can be increased work efficiency, low cost of manufacture, and can carry easily.
The technical solution adopted in the utility model is as follows: casing is handgun shape, and head is installed the cylinder that two homophases are arranged, and two volumes of cylinder equate that motor is installed at the middle part, and afterbody is installed the ABAP Adapter seat.Motor drives two piston assemblys through variable transmission mechanism, and piston assembly drives two piston to-and-fro motion in two cylinders respectively.Non-return air valve is installed on two cylinder tops, and the relief opening of valve communicates with gas tube, and the gas tube other end is in casing head outer end, and the gas tube head is installed the elastic packing assembly, during inflation with take turns nausea and chew and be connected.
Electronic pair of cylinder Tyre inflating machine of the present utility model, its variable transmission mechanism is: the small gear on the motor reel drives the gearwheel speed change, and gearwheel main shaft two ends are respectively installed an eccentric shaft, and two eccentric shafts drive two connecting rods respectively.The relative eccentric angle of two eccentric shafts is 180 degree.
Its piston assembly is: in the groove of piston outer ring rubber ring is installed, rubber ring can slide front and back in groove, and piston nose has aperture to be communicated with groove, and slide bar is installed in the rear end, and the slide bar afterbody is installed slide bar pin and articulated linkage.When piston advances forward, rubber ring is the hydrodynamic reciprocating sealing cylinder backward, and air in the compression cylinder.When piston moved backward, rubber ring moved forward, and air enters cylinder by pistion recess and aperture.
Its Non-return air valve is: two suction ports are communicated with two cylinder tops respectively in the valve, and two suction port the other ends respectively are provided with a valve ball, on the valve ball elastic spring are installed.Work as piston advances forward, the cylinder inner air pressure is during greater than elasticity of spring leaf, and the valve ball is opened, and air flows to gas tube through the relief opening of valve, and to tyre inflation.When piston moves backward, the cylinder inner air pressure is during less than elasticity of spring leaf, and the valve ball sealing closes suction port, makes that gas can't flow backwards in the tire.
Its elastic packing assembly is: spring is installed in gas tube head outer ring, and the spring front end is with the rubber ring washer.During inflation, spring pressure makes rubber ring washer and wheel nausea chew deadend, prevents gas leakage.
The utlity model has following characteristics:
1. inflator adopts two cylinders, two pistons.Because of two relative eccentric angles of eccentric shaft are 180 degree, when a piston advances forward, another piston moves backward during the compression cylinder air, sucks air in the cylinder.Certain aeration quantity, single chamber volume can dwindle half when adopting two cylinders, the also corresponding reduction of motor power (output).Improved working efficiency, and can reduce cost.
2. Non-return air valve adopts two suction ports, a relief opening in the inflator.Improved charging efficiency, simple in structure, and can reduced volume.
3. inflator is handgun shape, and volume is small and exquisite, and is easy to use.During inflation, the elastic packing assembly that is installed in the gas tube front end can prevent gas leakage effectively.
