| description | The invention discloses a passive vacuum storage tank with an air ejector. The passive vacuum storage tank comprises a manpower driving type inflating pump, a one-way valve a, a pressure gauge a, the air ejector, a one-way valve b, a pressure gauge b, a vacuum storage tank body and a vacuum breaking valve. The air ejector is used for making vacuum, the problems that a traditional manual vacuum pump is poor in vacuumizing performance and insufficient in vacuum degree are effectively solved, and the article storage quality is guaranteed. During vacuumizing, the manpower driving type inflating pump serves as a working fluid source of the air ejector, the problems that an electric vacuum pump cannot work under the condition of shortage of electric energy, the structure is complex, and the failure rate is high are effectively solved, storage under the passive condition is guaranteed, the high vacuum degree is obtained only through manpower, and the passive vacuum storage tank is suitable for working in special sce |
