The earliest acquisition and application of vacuum can be traced back to the 6th century BC, when China's ironmaking technology had already made considerable progress. In order to melt iron, blast equipment was installed on the ironmaking furnace. The initial use of skin bag blower and bellows blower was called "Shan". The function of the bellows includes negative pressure suction and pressurized exhaust. The working principle is basically the same as that of the current reciprocating piston vacuum pump. This type of bellows had already become an important tool for ironmaking by 1367 AD. This is the earliest example of vacuum acquisition and application.

From the primitive water pump, it has developed into dozens of existing mechanical pumps, diffusion pumps, molecular pumps, cryogenic pumps, ion jet pumps, sublimation pumps, and more.

The vacuum acquisition capability has also developed from a few hundred pascals to the current high vacuum and ultra-high vacuum fields. The pumping speed, mechanical performance, and reliability have all been astonishingly improved.

There is a definite record in history that Europeans were the ones who achieved the 'vacuum'. In 1643, Italian Torricelli conducted an atmospheric pressure experiment. He used a slender glass tube with one end closed and a small groove for mercury, first pouring mercury into the open end of the glass tube until the entire tube was filled. Then press down on the opening, invert the glass tube in the mercury tank, and open the pressed opening. At this point, the height of mercury in the glass tube gradually decreases until it is 760mm above the liquid level of the small tank, and then it no longer decreases. Torricelli believed that the gap at the top of the glass tube was a "vacuum". Subsequently, his students Pascal and others moved the experiment to the mountains and found that the mercury column height was below 760mm, proving that atmospheric pressure is related to height.
