Abstract

The invention relates to the technical field of inflation pumps, in particular to a high-low pressure combined air pump. The air pump comprises a rack, a transmission assembly, a first inflation assembly, a second inflation assembly and a driving device, the transmission assembly comprises a driving wheel, a transition gear, a second one-way bearing, an eccentric wheel, a driven shaft, a driven wheel and a first one-way bearing, and the output end of the driving device is connected with the driving wheel; the driving wheel and the transition gear are respectively meshed with the driven wheel, and the eccentric wheel is connected with the driven shaft through the one-way bearing; the eccentric wheel is hinged to the input end of the first inflation assembly; the transition gear is connected with the input end of the second inflation assembly through the second one-way bearing; and the rotating direction of the first one-way bearing is opposite to that of the second one-way bearing. The driving device drives the first inflation assembly or the second inflation assembly to conduct inflation, the load of the driving device during operation is reduced, the power source needed for driving the first inflation assembly and the second inflation assembly is reduced, the weight of the air pump is reduced, and practicability is high.

Description

technical field [0001] The invention relates to the technical field of air pumps, in particular to a high-low pressure combined air pump. Background technique [0002] In recent years, with the continuous development of air pump technology, more and more inflatable devices have appeared in people's production and life. Inflatable devices are also popular because of their light weight and convenient storage. However, when inflating different inflatable appliances, the required inflators are also different. However, the two inflatable components of the existing combined air pump pump air at the same time, and the two inflatable components will interfere with the inflation process of the inflatable device; the load and loss of the driving device are large, and the transmission structure is complicated. Therefore, deficiency is very obvious, needs to provide a kind of solution badly. Contents of the invention [0003] In order to solve the above technical problems, the objec...
