The invention discloses a switch valve core. The core comprises a valve core column, a first O-shaped ring, a second O-shaped ring and a third O-shaped ring. The valve core column is cylindrical and equipped with a column body, an input hole, a first annular groove, a second annular groove, a third annular groove, two first cut grooves, two second cut grooves and two output holes. The input hole is formed by axially extending inward from one end of the column body at the pre-set depth. The first annular groove is formed by annularly sinking around the circumferential surface of the column body. The second annular groove is formed by annularly sinking around the circumferential surface of the column body. The third annular groove is formed by annularly sinking around the circumferential surface of the column body. The two first cut grooves are formed by sinking from the opposite positions of a second circumferential surface of the column body. The two first cut grooves communicate withone end of the column body and the first annular groove. The two second cut grooves are formed by sinking from the opposite positions of the second circumferential surface of the column body. The twosecond cut grooves communicate between the second annular grove and the third annular groove. The two output holes are formed by extending from radial direction of the groove bottoms of the two cut grooves and communicating with the input hole. The first O-shaped ring is disposed into the first annular groove of the valve core column in a sleeved manner. The second O-shaped ring is disposed into the second annular groove in a sleeved manner. The third O-shaped ring is disposed in a third annular groove of the valve core column in a sleeved manner.
Description
technical field [0001] The invention relates to the technical field of inflatable equipment, and more specifically refers to an inflator and its air storage tank, a switching valve and a switching valve core. Background technique [0002] Conventional pumps, especially manual pumps, are mainly used to inflate external objects (such as tires and spheres). [0003] At present, there are mainly two types of air pumps that are commonly operated by manpower. One is the direct air supply type, that is, the gas is directly injected into the external object when the user moves, and the other is the gas storage type, that is, the user is in the air. During the action, the gas is firstly injected and stored in the air storage tank, and then the air storage tank is used to inflate the external object when it is to be inflated. [0004] Yet above-mentioned two kinds of air pumps, no matter be direct air supply type or air storage type, all have its advantage, as the air pump of direct ...
