An air leak proof regulating structure of a mechanical pump

Abstract

An air leakage prevention adjusting structure of a mechanical pump is provided. The adjusting structure may be applied to a multi-channel pump. The multi-channel pump may comprise a body, an air pump assembly and a channel switching structure which are arranged in the body, and a panel matched on the body. The adjusting structure may be matched on the panel and may comprise a channel selection knob, a turntable and a power switch. The channel selection knob may be rotatably arranged on the panel. The turntable may be arranged in the body. The upper end of the turntable may be connected with the channel selection knob, and the lower end of the turntable may be matched with the channel switching assembly. A convex edge and a notch may be arranged on the turntable. A button for controlling the on-off of a power supply is arranged on the power switch, and is selectively matched with the convex edge and the notch of the turntable. A user only needs to operate the channel selection knob to control the two functions, so that the operation of the user is facilitated, and the condition of air leakage of the inflatable product caused by omission of the operation of the user is effectively avoided.

         4 . The air leak proof regulating structure of  claim 2 , wherein the lower end of the post rod is connected with a sealing ring. 
     
     
         5 . The air leak proof regulating structure of  claim 1 , wherein the air pump assembly comprises a motor, a pump body, a blade and a pump cover, the pump cover and the pump body cooperate to form a pump chamber, the blade is arranged in the pump chamber, the motor is arranged outside the pump chamber, and is connected with the blade: the pump cover is provided with two air vents, one of which is connected with the outside world, and the other is connected with the inner chamber of the body. 
     
     
         6 . The air leak proof regulating structure of  claim 5 , wherein the multi-channel pump further comprises an inflation and deflation switching assembly. 
     
     
         7 . The air leak proof regulating structure of  claim 6 , wherein the inflation and deflation switching assembly comprises an air exchange core and a push rod, the push rod is slidably arranged on the panel, and one side of the push rod is provided with a rack; the upper end of the air exchange core is connected with the outside, and the lower end is selectively connected with two air vents of the pump cover, the upper part of the air exchange core is provided with a gear which engages with the rack of the push rod. 
     
     
         8 . The air leak proof regulating structure of  claim 7 , wherein the inflation and deflation switching assembly further comprises a switch fixing plate, the switch fixing plate is connected in the body, and the push rod is slidably arranged on the switch fixing plate. 
     
     
         9 . A structure for selectively inflating one or more air chambers of an inflatable product, the structure comprising:
 a body;   an air pump positioned within the body;   a plurality of air interfaces provided on the body, each air interface being coupled to a respective air chamber of the inflatable product;   a channel selector having an operator actuatable input actuatable from an exterior of the body and a turntable;   a switch operatively coupled to the air pump to in a first state turn on the air pump and in a second state to turn off the air pump; and   a plurality of seals, each seal being positionable in a first position to contact a respective one of the plurality of air interfaces to seal the respective one of the plurality of air interfaces and in a second position to be spaced apart from the respective one of the plurality of air interfaces to permit air flow therethrough;   wherein a single actuation of the operator actuatable input controls both the state of the switch and the position of each of the plurality of seals.   
     
     
         10 . The structure of  claim 9 , wherein the single actuation causes a rotation of the turntable, the turntable having a convex edge which engages the switch and a notch which receives the switch.
