Some instruments need to realize positive pressure and negative pressure functions at the same time, and 2 vacuum pumps and 2 sets of pipelines need to be equipped, so that the complexity, the part cost and the volume of the instrument can be increased, and the application is limited. If the high-pressure ozone therapeutic apparatus can realize the functions of positive pressure and negative pressure, two vacuum pumps and a plurality of electromagnetic valves are required to be installed inside the high-pressure ozone therapeutic apparatus, each vacuum pump realizes one function, the positive pressure or negative pressure function is independently realized, the high-pressure ozone therapeutic apparatus needs two vacuum pumps, a plurality of electromagnetic valves and two sets of pipelines, the complexity, the hardware cost and the size of the apparatus are increased, the apparatus is inconvenient to carry, the cost of the whole apparatus is higher, and the use scale and the use scene are limited. The negative pressure aspirator is only provided with a vacuum pump and a plurality of pipelines, but can only realize the negative pressure function without the positive pressure function, and can not realize the seamless conversion of the positive pressure and the negative pressure although being made portable. In order to solve the problems, the invention is specially invented.

SUMMERY OF THE UTILITY MODEL
