Description

Inflating fan Technical Field The utility model relates to the technical field of fans, in particular to an inflatable fan. Background At present, the inflation fan is widely applied to inflation operation of products such as tires, inflatable swimming pools, tents, surfboards and the like. However, in order to ensure the inflation effect, the existing inflation fan is externally connected with a pressure detector at an air outlet of the inflation fan, so that after the inflation fan stops inflating, the pressure is gradually reduced due to the fact that a valve is not tightly sealed or a pipeline leaks air, frequent air supplement is needed, and particularly inconvenience is caused to long-term use of a large-sized inflation product (such as an inflation pool), and the air tightness is not tight, so that the dial plate of the instrument cannot accurately display the pressure in the current object to be inflated, the pressure control precision is insufficient, and the use efficiency is affected.
