Embodiment Construction

[0018] The present invention will be further elaborated below by means of the accompanying drawings and examples. like figure 1 As shown, a passive vacuum storage tank with an air ejector includes a human-driven air pump 1, a one-way valve a2, a pressure gauge a3, an air ejector 4, a one-way valve b5, and a pressure gauge b6 , vacuum storage tank 7 and vacuum breaking valve 8;

[0019] The inlet of the human-driven air pump 1 is directly connected to the atmosphere, and the outlet is connected to the inlet of the one-way valve a2 through the gas pipeline;

[0020] The outlet of the one-way valve a2 is connected with the working fluid inlet of the air injector 4 through a pipeline;

[0021] The pressure gauge a3 is installed at the working fluid inlet of the air ejector 4 for displaying the pressure of the working fluid of the air ejector 4;

[0022] The injection fluid inlet of the air ejector 4 is connected to the outlet of the one-way valve b5, and the outlet of the air e...

Abstract

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 scenes (passive).

Description

technical field [0001] The invention belongs to the technical field of vacuum storage, in particular to a passive vacuum storage tank (cabinet) with an air injector. Background technique [0002] With the continuous improvement of living standards, people have higher and higher requirements for storage. In addition to ordinary grain and food, the stored items also include medicines, off-season clothes, books, etc. People often put these items in traditional Boxes, plastic boxes and plastic bags are stored in relatively humid places, especially during the annual rainy season in southern my country, problems such as mold and moths are particularly serious, which greatly reduces the life of the items. The vacuum storage technology can fundamentally solve the problem of sealed storage. By forming a vacuum storage in a low-oxygen and low-pressure (negative pressure) state inside the vacuum storage tank (cabinet), it can effectively prolong the moisture conversion, mildew and oxida...
