Description

Pistol type electric inflating machine

It is the equipment of the tyre inflation of vehicle that the utility model relates to a kind of, particularly a kind of pistol type electric inflater.

Being generally inflating tyres of vehicles is to use manual pump, has both expended muscle power, and speed is slow again, and what have is tyre inflation with pressurized air, needs a bigger gas holder, and equipment is comparatively expensive, is difficult for applying.

The utility model purpose is to overcome the shortcoming in the above-mentioned technology, provide a kind of and utilize that electric power is small and exquisite as power, structure, easy-to-operat and the pistol type electric inflater that carries, be specially adapted to the tyre inflation of bicycle, tricycle, special cycle for disabled people and motorcycle.

Goal of the invention of the present utility model realizes by following technological scheme: this pistol type electric inflater, be connected with air compressor by retarder by micro motor, micro motor is contained in the intracavity of handle of a handgun shape, its switch is contained in the position that handle below finger is convenient to pull, the output shaft of micro motor is connected with input shaft of speed reducer, the output shaft of retarder is connected with the bent axle of air compressor, two or more cylinders are arranged in the air compressor, piston in the cylinder connects on the bent axle by connecting rod, end in cylinder block has the compression air valve, this air valve is made up of valve block, adopt an end to fix, the Reed Valve structure that the other end can open and close, the buffer end is adorned one to pressing the gas that comes can play the valve block of non-return effect, and gas delivery port and the adjustable valve that can align the buffer internal pressure are housed on the sidewall of buffer.

Each cylinder end is generally formed the compression air valve by two valve blocks, one end of valve block is fixed, the other end is subjected to the effect of valve block both sides gas pressure difference can open and close, but each valve block can only be opened to a direction, two valve blocks at a cylinder end must be opened to two different directions, make two valve blocks of a cylinder be in respectively simultaneously in air inlet with when giving vent to anger respectively and close (or open) position.The thickness of valve block is generally the 0.1-0.2 millimeter, and flexible movements adapt to the piston needs of high-speed motion back and forth.Piston back and forth movement at a high speed, piston and piston ring and cylinder inner wall have high-speed friction, can produce a large amount of heats block temperature is raise, for heat radiation better, the transverse annular fin is arranged on cylinder block outer wall, increase heat diffusion area, increase rate of cooling.

A small pressure table is installed on the buffer top, but the pressure in the look aside buffer at any time.When the pressure in the buffer and needed pressure are higher or on the low side, can adjust adjustable valve, be required pressure with the pressure in the controller buffer.The specification of small pressure table as required, optional range is 4 * 10^5N/M^2.

The utility model has the advantages that with electric power to be power, exempted physical fatigue, structure is small and exquisite, operates and carry all very convenient, and aeration speed is fast, is the ideal tools that various inflating tyres of vehicles are used.

Embodiment of accompanying drawings:

Fig. 1 is the structural drawing of pistol type electric inflater, and wherein: (1) is handle, and (2) are switches, (3) be bearing, (4) are retarders, and (5) are the air compressor cylinder bodies, (6) be the air compressor loam cake, (7) are bent axles, and (8) are link rods, (9) be piston, (10) be valve block, (11) are the holes, and (12) are that buffer (13) is a valve block, (14) be the small pressure table, (15) be the hole, (16) are valve blocks, and (17) are valve blocks, (18) be the hole, (19) be the hole, (20) are valve blocks, and (21) are the transverse annular fins, (22) be adjustable valve, (23) are the pressurized air delivery outlets.

In the present embodiment, its power of the micro motor of selecting for use is 300 watts, 220 volts, and 6 peaces; Shape resembles the handle of pistol and the supporting shell of micro motor is an assemblying body, makes with plastics injections, also can select other material for use certainly, as cast aluminium etc.Switch (2) is below handle.Retarder (4) is mainly formed double reduction gear by the different steel gears of four diameters, and rotating speed designs at 1600 rev/mins.What be connected with reducer output shaft is the bent axle (7) of air compressor, and air compressor is combined by loam cake (6) and cylinder body (5), is cast with transverse annular fin (21) on the cylinder body and is used for air cooling and heat radiation.Two cylinder holes vertically are arranged side by side, and the to-and-fro motion of piston drives piston by micro motor by bent axle, link rod, and the to-and-fro motion of piston realizes suction, the discharge of gas.The compression air valve is made up of 5 valve blocks (10), (13), (16), (17), (20) in the bottom of cylinder body (5), and these 5 valve block one ends are fixed, and the other end can freely openable, and motion adapts to that this machine is miniature, the characteristics of high speed flexibly, at a high speed.Piston (9), link rod (8) are aluminium alloy castings, and piston ring is that polytetrafluoroethylmaterial material is made.

When first order piston promoted, gas was sucked by hole (18), and valve block (20) is in closed condition, and valve block (17) is opened; With second level piston decline for the moment, valve block (10) is closed, valve block (16) is opened, gas in the jar is discharged through via hole (15) by hole (11), and a valve block (13) is adorned in the buffer lower end, to pressing the gas that comes to play non-return effect, promptly can only arrange, and can not discharge buffer, can only need the tire of inflation by pressurized air delivery outlet (23) input to buffer.Buffer is a cylindrical shape, and 2 millimeters of wall thickness are made with seamless steel pipe.It is 4 * 10^5N/M^2 that small pressure table (24) is selected its range, and adjustable valve (22) can be set up voluntarily according to required pressure, exits during superpressure.The utility model air displacement is the desirable inflatable tools of vehicle tire such as bicycle, rickshaw, motorcycle less than 1 cubic metre/minute.
