The siphon pot originated in 1830-1840. Loeff in Berlin, Germany, first invented the siphon extraction method of glass and upper and lower pots. Later, it became popular in the 1950s through continuous improvement in France, Britain, Germany and other countries.

Another theory is that in 1840, the Scottish engineer Robert Naier invented the siphon pot, which was patented by France's Madame Vassieux and started production in Britain and Germany in the 1850s. In the middle of the 20th century, it was brought to Denmark and Japan respectively, and began to enter the market on a large scale.

Among them, the Japanese like the siphon pot technology, carefully consider the size of coffee powder, the complex relationship between water and time, and develop regular coffee utensils. While the Danes pay attention to functional design, in the mid-1950s, Peter Bolton (Peter Bodum), who imported siphon pots from France, felt that French-made pots were expensive and difficult to use, so he worked with the architect Kaas Klaeson to develop Bolton's first styling siphon pot, which went to market under the name "santos". In 1924, the Japanese company KONO commercialized the coffee machine and named it "siphon pot". )

According to the book left-handed Coffee, right-handed World, in 1909, Salem, Massachusetts, had two sisters who invented the quartz glass siphon pot based on the French vacuum pot invented by Ms. Vasser in the 1840s.

Siphon principle siphon (siphon) is a hydrodynamic phenomenon that can pump liquids without the aid of pumps. After the liquid in the higher position is filled with an inverted U-shaped tubular structure (called a siphon), it opens to a lower position. In this structure, the liquid pressure difference between the two ends of the tube can push the liquid over the highest point and discharge to the other end, mainly by the action of gravity on the siphon. The liquid at the highest point in the tube moves to the mouth of the low tube under the action of gravity to form a vacuum. Under the action of vacuum, the liquid at the mouth of the high tube is sucked into the highest point, forming a siphon phenomenon.
