Model utility content
The purpose of this utility model is to provide a kind of air pump connecting rod piston assembly, solves and how to avoid connecting rod piston assembly operationally to produce the larger noise convenient technical problem manufactured simultaneously.
Another object of the present utility model is to provide a kind of air pump using above-mentioned air pump connecting rod piston assembly.
Air pump connecting rod piston assembly, comprises connecting rod, piston, piston ring; Piston lateral edge has the groove of annular; Being piston top flat above groove, is piston egative film below groove, piston egative film has the inlet hole group be made up of multiple inlet hole, these inlet holes all with groove UNICOM; The flexible piston ring of groove inner sleeve, the height of this piston ring is less than the distance between piston top flat and piston egative film thus makes to have gap in a longitudinal direction between piston ring and piston.
Also there is directly over described inlet hole and inside groove the air inlet duct towards sunken inside.
Described inlet hole always has four, and what air inlet duct was corresponding also has four.
Described piston ring is rubber parts.
Described rubber parts is fluorine rubber part.
Upper and lower two positions of described piston ring side direction are protruded outwardly, middle then have annular towards the oil storage tank of sunken inside.
Air pump, comprises motor, eccentric wheel, air pump connecting rod piston assembly; Motor is connected with air pump connecting rod piston assembly by eccentric wheel; Described air pump connecting rod piston assembly, comprises connecting rod, piston, piston ring; Piston lateral edge has the groove of annular; Being piston top flat above groove, is piston egative film below groove, piston egative film has the inlet hole group be made up of multiple inlet hole, these inlet holes all with groove UNICOM; The flexible piston ring of groove inner sleeve, the height of this piston ring is less than the distance between piston top flat and piston egative film thus makes to have gap in a longitudinal direction between piston ring and piston.
Also there is directly over described inlet hole and inside groove the air inlet duct towards sunken inside.
Described inlet hole always has four, and what air inlet duct was corresponding also has four.
Described piston ring is rubber parts.
Described rubber parts is fluorine rubber part.
The beneficial effects of the utility model are:
1, air pump working life is added.Because piston ring adopts rubber product, its hardness is former in 1/4th of teflon (plastics) the sheet ring that is material, obviously little with the frictional force of cylinder, add wear-resisting, moisture-proof, oil resistance that fluorine rubber is good, the service time of piston ring and cylinder is greatly improved.
2, good lubrication effect.The lubrication effect of the working life of air pump and energy consumption and its system has direct relation, novel piston ring adopt upper and lower two positions to protrude outwardly two circle sword structure, overall in " m " type, fluted in the middle of two round sword, heating and the energy consumption of this to be high performance oiling agent be lubrication friction system of medium reduce greatly.
3, noise is reduced.The mode of being slidably connected of piston ring and piston body make the air inlet channel of air pump become from however unimpeded, almost there is no sound during every task, eliminate in original system due to noise that the continuous percussion of air inlet spring sheet and piston produces.
4, rational in infrastructure.Exquisite connecting rod adopts four gas inlet hole patterns, ensure that the unimpeded of air inlet channel, is connected makes the energy consumption of air pump and noise become little as far as possible with the bearing at bent axle position.
5, improve air pump efficiency and become possibility.Due to above-mentioned advantage, the single work distance of cylinder bore 22mm air pump rises to 17mm by original 14mm, efficiency improves 21.4%, the single work distance of diameter 25mm air pump rises to 18mm by original 14mm, efficiency improves 28.6%, working life extends twice, makes the total quality of automobile inflator pump obtain the lifting of matter.
6, product structure parts are little, and assembling more for convenience.

Embodiment
Please refer to Fig. 2 to Fig. 5, the air pump connecting rod piston assembly in figure, comprise a connecting rod 1, piston 2, piston ring 3.
Connecting rod 1 can adopt and strengthen nylon or Al-alloy parts, and it is Common parts.
Piston 2 is integral with connecting rod 1, and this piston 2 lateral edge has the groove 21 of annular for entangling the piston ring 3 of fluorine rubber part.Being piston top flat 22 above groove 21, is piston egative film 23 below groove 21, piston egative film 23 has the inlet hole group be made up of four inlet holes 231, these inlet holes 231 all with the air in groove 21 UNICOM such groove 21 just can with inlet hole 231 UNICOM; In order to make air can better by groove 21 and inlet hole 231, that goes back correspondence directly over each inlet hole 231 and inside groove 21 has an air inlet duct 24 towards sunken inside, makes more air can circulate between groove 21 and inlet hole 231 like this.The height of above-mentioned piston ring 3 is less than the distance between piston top flat 22 and piston egative film 23 thus makes to have gap in a longitudinal direction between piston ring 3 and piston 2.In order to improve piston ring 3 and the lubrication effect of piston body, upper and lower for piston ring 3 side direction two positions can be protruded outwardly, middle then circularize the oil storage tank 31 caved in inwardly.
When being exhausted work in air pump cylinder body, piston ring 3 and piston top flat 22 are fitted, like this because piston top flat 22 does not have hole thus form sealing configuration and complete exhaust work like this; When carrying out air-breathing work in air pump cylinder body, piston ring 3 and piston egative film 23 are fitted, and reach the effect of air-breathing at this moment air flow into piston egative film 23 inlet hole 231 from piston ring 3 and the gap of piston egative film 23.
