Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
As depicted in figs. 1 and 2, a kind of piston of gas-filled pump comprises the piston head 11 of piston rod 12 and plate-like, and an end of piston rod 12 is connected to the middle part of piston head 11, it is characterized in that, the position of departing from the middle part on the piston head 11 is provided with suction valve.According to structure of piston and movement locus, the space of the cylinder of gas-filled pump is divided into rod chamber and rodless cavity, along with the motion of piston, the inner space of rod chamber and rodless cavity constantly changes.When piston is done air-breathing motion, be positioned at the INO on the piston head 11, outside air enters in the rodless cavity via suction valve, and pressure and external pressure in the rodless cavity reach unanimity, and have reduced the resistance when piston is pulled out, and have reduced the kinetic equation loss of gas-filled pump.When piston was done compression movement, the gas in the rodless cavity was compressed, and the pressure in the rodless cavity is greater than the pressure of cylinder outside, and suction valve is pressed on the piston head 11, gas leak phenomenon can not take place.Further, suction valve comprises the valve opening 13 that is arranged on the one or more perforations on the piston head 11, and is arranged on the front-end face of piston head 11 and covers the valve block 14 of valve opening 13.When piston was done air-breathing motion, the rodless cavity internal gas was thin, and the pressure of rodless cavity is less than rod chamber, and extraneous gas backs down valve block 14 via valve opening 13, and INO, gas enter in the cylinder of gas-filled pump.The valve opening 13 of suction valve is arranged on the disk-shaped piston 11, and is easy to process, reduced the cost of gas-filled pump.The valve block 14 of suction valve is an one-way valve, and gas spills from suction valve in the time of can preventing the gas-filled pump pressurized gas.Preferably, valve opening 13 is a plurality of, and when valve opening 13 when being a plurality of, a plurality of valve openings 13 can evenly distribute on piston head 11, and what of valve opening 13 are relevant with the diameter and the inflation pump delivery of piston head 11.
As depicted in figs. 1 and 2, the front end of piston head 11 also comprises newel 15, and valve block 14 is sheathed on the newel 15.Newel 15 has played leading role when valve block 14 assemblings, after valve block 14 was placed in newel 15, newel 15 had limited valve block 14 motion radially, has played the effect of radial location.Preferably, valve block 14 is riveted mutually with piston head 11, has limited the axial motion of valve block 14, has played the effect of axially locating.Further, piston head 11 also comprises compressing tablet 16, and compressing tablet 16 is pressed on the valve block 14, and sheathed being fixed on the newel 15.Compressing tablet 16 is used for fixing valve block 14, and like this, when gas passed through valve block 14 via valve opening 13, the position that valve block 14 is pushed down by compressing tablet 16 was motionless, and the external opening of valve block 14, gas enter the rodless cavity of cylinder.In addition, compressing tablet 16 is riveted mutually with piston head 11, the axial motion of restriction compressing tablet 16.
As depicted in figs. 1 and 2, the pressure ring 18 that also comprises piston ring 17 and fixed piston ring 17 on the piston head 11.Piston ring 17 is positioned at the periphery of piston head 11, and pressure ring 18 is positioned on the piston ring 17, is used for fixing piston ring 17.Further, piston ring 17 is the bowl shaped structure that has intermediate throughholes, comprises the joint on plane and from the outer edge of joint towards the place ahead and outside diagonally extending.Pressure ring 18 is positioned on the plane joint of piston ring 17, more helps fixing piston ring 17.The outer edge of the diagonally extending of piston ring 17 is compared with the piston ring of vertical edge, is more conducive to reduce the resistance of piston motion.
Shown in Fig. 3 and 4, a kind of gas-filled pump, the piston 1 that comprises housing 3, is arranged on the cylinder 2 on the housing and cooperates with cylinder, piston 1 is each described piston in the claim 1 to 6, the piston head 11 of piston 1 matches with the inwall of cylinder 2, and the suction valve on the piston head 11 is communicated with the rod chamber and the rodless cavity of cylinder 2.Further, the end wall of the upper end of cylinder 2 is provided with air outlet hole, the inlet end of lower end for opening wide.
Shown in Fig. 3 and 4, gas-filled pump also comprises: motor 4, and housing 3 is connected the output terminal of motor 4; Pressure gauge 5 is with the rodless cavity gas communication of cylinder 2.Motor 4 provides power for gas-filled pump.Because the existence of pressure gauge 5, the user can observe the pressure of the gas of cylinder 2 discharges very easily at any time.
Further, as shown in Figure 4, gas-filled pump also comprises head lamp 6, is connected on the motor 4 the other end opposite with housing 3.Head lamp 6 can be beacon or lighting burner, is convenient to use at night.
As can be seen from the above description, the utility model the above embodiments have realized following technique effect:
Gas-filled pump of the present utility model and piston thereof, its piston comprises the piston head of piston rod and plate-like, and an end of piston rod is connected to the middle part of piston head, and the position of departing from the middle part on the piston head is provided with suction valve.When piston is air-breathing, INO, gas sucks from suction valve, has reduced the resistance when piston is pulled out, therefore the kinetic equation loss that has reduced this piston and had the gas-filled pump of this piston.In addition, when pressurized gas, suction valve cuts out, and can not influence the proper functioning of gas-filled pump.
The above is a preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
