Handwheel 31 " can be arranged at the blow vent 121 " of control panel 12 ", and gas can be arranged on handwheel 31 " at this timeMouthful, which is connected to first chamber.
The microswitch that control motor 21 " starts or closes is also associated in the present embodiment on pump cover 24 ", correspondingly,The periphery of rotating disk 33 " sets that there are two the shake-up blocks 333 " that coordinate with microswitch.Handwheel 31 " is set there are three gear, is respectivelyInflation gear closes gear and deflation gear, and under normality, handwheel 31 ", which is in, closes gear, at this point, rotating disk 33 " closes pump cover24 " air inlets 241 " and 24 " gas outlet 242 " of pump cover.When aerated product needs to be inflated, rotation handwheel 31 " to inflation shelvesPosition, first chamber are connected to pump housing chamber via third blow vent 131 ", the first blow vent 331 " with 24 " air inlet 241 " of pump cover,And pump housing chamber is connected to second chamber via 24 " gas outlet 242 " of pump cover with the second blow vent 332 " 332 ".Rotating disk 33 " is convenientlyIt takes turns in 31 " rotation processes, touch switch contacts microswitch one of in rotating disk 33 ", to starter motor 21 ".HorseImpeller 23 " rotates after starting up to 21 ", and under the effect of impeller 23 ", extraneous gas enters first chamber by 31 " stomata of handwheel,Then enter pump housing chamber through third blow vent 131 ", the first blow vent 331 " and 24 " air inlet 241 " of pump cover, then from the pump housingChamber enters second chamber through 24 " gas outlet 242 " of pump cover and the second blow vent 332 " 332 ", finally from second chamber through charge and dischargeGas port 111 " enters in aerated product, realizes the inflation to aerated product.After the completion of inflation, rotation hand wheel 31 " is adjusted to closingGear, during rotating disk 33 " is rotated with handwheel 31 ", the above-mentioned shake-up block 333 " in rotating disk 33 " can be contacted again tactileDynamic switch, to close motor 21 ".
When product is deflated, rotation handwheel 31 " is to deflation gear, and first chamber is via the 4th blow vent132 ", first blow vent 331 " is connected to pump housing chamber with 24 " gas outlet 242 " of pump cover, and pump housing chamber is via 24 " air inlet of pump coverMouth 241 " is connected to second chamber with the second blow vent 332 ".Rotating disk 33 " is in 31 " rotation process of handwheel, in rotating disk 33 "Another touch switch contacts microswitch, to starter motor 21 ".Impeller 23 " rotates after motor 21 " starts, in leafUnder 23 " effect of wheel, gas in aerated product enters second chamber by charge and discharge gas port 111 ", then through the second blow vent 332 " and24 " air inlet 241 " of pump cover enters pump housing chamber, then from pump housing chamber through 24 " gas outlet 242 " of pump cover, the first blow vent331 " and the 4th blow vent 132 " enter first chamber, finally from second chamber through 31 " stomata of handwheel be discharged, realize to inflation produceThe deflation of product.After the completion of deflation, rotation hand wheel 31 " during rotating disk 33 " is rotated with handwheel 31 ", is revolved to gear is closedThe above-mentioned shake-up block 333 " of turntable 33 " can be contacted again touch switch, to close motor 21 ".
The inflation/deflation structure of the pumping makes 12 " blow vent 121 " of control panel be connected to pump cover 24 " by adjusting rotating mechanismThe charge and discharge gas port 111 " of air inlet 241 " and ontology 11 " is connected to 24 " gas outlet 242 " of pump cover, logical to provide inflation for pumpingRoad, to realize the inflation work of pumping；12 " blow vent 121 " of control panel connection pump cover 24 " is set to go out by adjusting rotating mechanismThe charge and discharge gas port 111 " of gas port 242 " and ontology 11 " is connected to 24 " gas outlet 242 " of pump cover, logical to provide deflation for pumpingRoad, to realize the deflation operations of pumping.The inflation/deflation structure of the pumping realizes pumping without using check valveCharging-discharging function, the inflation/deflation structure greatly reduce the volume of pumping, simplify the structure of pumping, reduce the production of pumpingCost.
The above is only the utility model embodiment, not makees any limit to the technical scope of the utility modelSystem, thus any trickle amendment made by the above technical examples according to the technical essence of the present invention, equivalent variations with repairDecorations, are still within the scope of the technical solutions of the present invention.
