Embodiment

Of the present utility model a kind of embodiment as shown in Figures 2 and 3, have direct current generator 1, dissipating cover 2, lower cover 3, middle cover 4, loam cake 5, give vent to anger cover 6, eccentric axle bed 7, eccentric pedestal 8, eccentric shaft 9 and cylinder 10; Be with damping washer 11 on the motor 1, both are placed in the lower cover together, lower cover 3 is screwed with motor 1 and is connected, a dissipating cover 2 is placed in the lower cover bottom, the lower cover bottom has suction port 14, eccentric axle bed 7 is fixedlyed connected with motor, cylinder 10 is placed on the eccentric pedestal 8 and is being provided with check sheet 16 at cylinder end, place middle cover 4 above the cylinder, on middle cover, place loam cake 5, between lower cover and the middle cover, all connect between middle cover and the loam cake, place the sealing gasket of making by flexible rubber material 19 between middle cover and the loam cake, on loam cake 5, be with O type circle 12 with bolt, on cover that being placed with gives vent to anger covers 6, giving vent to anger to cover is connected with steam outlet pipe 13, has a polygonal positioning hole 15 on eccentric axle bed 7, and eccentric shaft 9 lower ends are positioned in the positioning hole, fixedly connected with eccentric pedestal 8 in the upper end.

Cylinder 10 is made by high recovery flexible rubber material, and cylinder includes 4 cylinder bodies 17 that are connected as a single entity, and each cylinder body 17 bottom all is provided with check sheet 16.Eccentric pedestal 8 is provided with 4 gas-entered passageways 18, and this gas-entered passageway 18 was positioned at check sheet 16 belows after cylinder was placed on the eccentric pedestal.

As shown in Figure 4, among the figure, A is an active chamber, and B is that cylinder is in stretch position, and C is that cylinder is in the release location, and D is last air outlet, and E is last gas storehouse, and 1-5 represents the position of 5 check sheets.

According to the air flows position shown in the arrow among Fig. 2 and Fig. 4 as can be known air enter lower cover 3 by bottom dissipating cover 2, enter in the active chamber A by the suction port 14 that covers down, when needs are inflated, open control switch, motor 1 is started working, and drives eccentric axle bed 7 and stretches and release motion.The cylinder that is in stretch position B is because the increase of cylinder body volume, gas pressure intensity in the cylinder body is lower than a barometric pressure, the air that be in the active chamber A this moment is opened check sheet 1 by the gas-entered passageway 18 on the eccentric pedestal 8 after the poor influence that is stressed, enter cylinder interior, cylinder is finished in the air-breathing work of stretch position B at this point.Rotation along with eccentric pedestal 8, when cylinder arrives release location C, the cylinder body volume-diminished, the cylinder interior gas compression, poor influence is stressed, check sheet 2 closures, gas in the cylinder body can not be discharged in the active chamber A, just can only support and open top check sheet 3 and check sheet 4, enter into gas storehouse E by last air outlet D, and this moment check sheet 5 owing to the influence of pressure difference, near the cylinder closure, effectively prevented the adverse current of air, the air of finally going up in the E of gas storehouse just enters into steam outlet pipe 13 by total air outlet, has finished the process of exhaust.Under the continuous driving of motor, eccentric pedestal 8 back and forth stretches and releases motion, drives cylinder and constantly carries out air-breathing and exhaust, makes air continuously discharge the pump housing, has reached the purpose of exchanging the inflation of solar term capsule.

Cylinder adopts the flexible rubber material with high recovery to make, and the tight closure of check sheet 2 in the exhaust process, and effective closure of check sheet 5 make that all cylinder has good sealing property, finish the process of whole inflation effectively.Between middle cover and loam cake, place the sealing gasket of making by flexible rubber material 19 simultaneously, also effectively prevented the leakage of gas.

The utility model load is little, power consumption is low, simple in structure and tight, have good market prospects.

Existing gas-filled pump as shown in Figure 1, by the A place as can be known, eccentric axle bed is fixedlyed connected with eccentric shaft, and the eccentric pedestal in B place separates with eccentric shaft, and eccentric shaft is supporting eccentric pedestal, when cylinder moves, eccentric axle bed of driven by motor and eccentric shaft move simultaneously, and eccentric shaft drives the gentle cylinder of eccentric pedestal again and moves together, so that motor load is very big, the mutual tractive motion of cylinder, power consumption is big.D is expressed as cylinder among the figure, and C represents suction port, and above suction port was arranged on, cylinder was from top to bottom air-breathing, makes whole air pump structure complexity.
