Air bag air inflating and air pumping device

Abstract

The invention belongs to the technical field of air inflating and air pumping devices, and provides an air bag air inflating and air pumping device. The air bag air inflating and air pumping device comprises an air bag and air valve unit, an air pump unit and an air inflating and air pumping switching valve unit; the air bag and air valve unit is connected with the air inflating and air pumping switching valve unit, and the air inflating and air pumping switching valve unit is connected with the air pump unit; the air bag and air valve unit comprises an air bag and air valve set which comprises an air bag and one or two air valves, and the air pump unit comprises an air inlet and an air outlet for providing power for air inflating and air pumping; and the air inflating and air pumping switching valve unit comprises a three-way valve. Without adding additional costs, the air bag air inflating and air pumping device utilizes a ready-made air pump to reversely pump the air bag, compared with natural deflation, the deflation speed of the air bag is higher and constant, and the advantage that the deflation speed is not affected by external factors is achieved; and meanwhile, according to the air bag air inflating and air pumping device, air inflating and air pumping share the air pump, and thus the cost and a structural space are greatly saved.

Description

technical field [0001] The invention belongs to the technical field of inflating and pumping devices, in particular to an air bag inflating and pumping device. Background technique [0002] In the prior art, the airbag can be combined into an inflatable and pumping device by being connected with components such as an air pump, an air valve, and a trachea. Since the airbag itself can adjust its height and hardness by inflating and deflated, the airbag including the airbag The inflation and suction device also has a regulating function accordingly. Among them, the inflation of the airbag is realized by using an air pump, and the inflation speed is proportional to the air flow of the air pump and the number of air pumps, and the inflation speed is constant. Air pump, so that the air bag has a fast enough inflation speed. However, for the deflation of airbags, because the current airbags usually adopt a simple structure, that is, each airbag is connected to a trachea, and the ...
