Who invented the vacuum cleaner and when was the vacuum cleaner invented

In 1901, British civil engineer Booth went to the Imperial ** Hall in Leicester Square, London, to visit a demonstration of a car case dust collector in the United States. This vacuum cleaner uses compressed air to blow dust into the container, which Booth doesn't think is clever because much of the dust fails to blow into the container. Later, he did the opposite, and using the vacuum method, Booth made a very simple experiment:

A handkerchief is placed on the arm of a chair and the handkerchief is sucked off with your mouth, resulting in a layer of dust attached to the handkerchief. At that time, he made a vacuum cleaner, used a powerful electric pump to suck air into a hose, and filtered the dust through a cloth bag. In August 1901, Booth obtained a patent and established a vacuum cleaning company, but it was not a vacuum cleaner.

He put it with a gasoline engine.

Driven vacuum pumps.

Loaded on a horse-drawn carriage, door-to-door service, three or four long hoses were put into the room through the window to vacuum the dust, and the employees of the company put on work clothes. This was the predecessor of the late vacuum cleaner.

Sanyo Sanyo horizontal vacuum cleaner.

In 1902 Booth's service company was summoned to Westminster Abbey to bring Edward VII.

The carpet used for the coronation ceremony was cleaned. Since then, business has been booming. In 1906 Booth made a small household vacuum cleaner, albeit named.

small", but the vacuum cleaner weighs 88 pounds (1 pound = kilogram) and is too bulky to be popularized.

Ohio, USA, 1907.

Spengera, the inventor of the company, made a lightweight vacuum cleaner, who was working as a caretaker in a shop at the time, made a vacuum cleaner and an electric fan to reduce the burden of sweeping carpets.

A vacuum is created to suck dust into the machine and then blow into the pocket. Since he was incapable of producing and selling himself, he transferred the patent to the fur manufacturer Hoover in 1908.

Hoover began to manufacture an "O" type vacuum cleaner with wheels, which sold quite well, and the design of this earliest household vacuum cleaner was relatively reasonable, and there has not been much change in principle to this day.

The earliest designs of vacuum cleaners were upright. Stockholm, Sweden, 1913.

Winle Goering invented the horizontal canister vacuum cleaner.

In 1901, Booth, a British civil engineer.

The invention of wall "vacuum cleaners" abroad specializes in the treatment of all kinds of small advertisements and **city** diseases.

In 1901, Booth, a British civil engineer, invented the vacuum cleaner. He went to the Imperial ** Hall in Leicester Square, London, to see a demonstration of a car case duster in the United States. This vacuum cleaner uses compressed air to blow dust into the container, which Booth doesn't think is clever because a lot of hail dust doesn't get into the container.

Later, he did the opposite, vacuuming, and Booth made a very simple experiment: he put a handkerchief on his mouth and nose, and inhaled the handkerchief with his mouth, and the result was that the handkerchief was covered with a layer of dust. So, he made a vacuum cleaner and used a powerful electric pump to suck air into a hose and filter the dust through a cloth bag.

According to the structure, vacuum cleaners can be divided into vertical, horizontal and portable. The working principle of the vacuum cleaner is to use an electric motor to drive the blades to rotate the bald sail at high speed, which is generated in a sealed shell.

Cleaning vacuum cleaner, invented in 1997, 21 years ago, we innovatively invented the sanitation vacuum cleaner, which changed the development direction of the sanitation vacuum cleaner, and has been leading a new era of vacuum cleaning in the following 21 years. Pure suction structure, more concise structure, more convenient operation, no need to replace the sweep brush frequently, low cost of use is a major feature of the wind vacuum cleaner. The primary dust collection rate reaches 99%, which greatly improves the dust collection efficiency, and the pure suction operation with patented technology completely solves the problem of secondary dust that is a headache for traditional sanitation vehicles, and the dust collection truck takes the lead in realizing all-weather all-weather and all-terrain operations.

In which year was the vacuum cleaner invented.

Dear, I am glad to answer the <> for you

Cleaning vacuum cleaner, invented in 1997, 21 years ago, our innovative old touch invented the sanitation vacuum cleaner, since then changed the development direction of the sanitation vacuum cleaner, and has been leading a new era of vacuum cleaning in the following 21 years. Pure suction structure, more concise structure, more convenient operation, no need to replace the sweep brush frequently, low cost of use is a major feature of the wind vacuum cleaner. The primary dust collection rate reaches 99%, which greatly improves the dust collection efficiency, and the pure suction operation with patented technology completely solves the problem of secondary dust that is a headache for traditional sanitation vehicles, and the dust collection truck takes the lead in realizing all-weather all-weather and all-terrain operations.

Extended information: In China's sweeper market, the share of suction sweeper sweeper is more than 95%. The second stage (the 80s to the end of the 90s in the 20th century) is the fastest stage of the development of sweepers in China, and the use of sweepers not only extends from large and medium-sized cities to small cities, but also expands from urban roads to highways and highways.

Who is the inventor?

You're experiencing something right now.

Vacuum cleaners are meant to dispose of garbage, but they are creative when used to tease the earth's environment. He warns us that human pollution and discourse on the environment can no longer be controlled by our own power, and that it needs to be dealt with with by a vacuum cleaner the size of a planet (metaphor), and that it needs to be dealt with day and night; It is urgent to protect the earth's environment; The use of children's illustrations also warns people to leave a beautiful environment for children, and environmental education starts with children.

According to the structure, vacuum cleaners can be divided into vertical, horizontal and portable. The working principle of the vacuum cleaner is to use an electric motor to drive the blades to rotate at high speed, generate air negative pressure in the sealed housing, and suck up dust. In September 2012, the output of household vacuum cleaners in China was 10,000 units.

The vacuum cleaner is mainly composed of three parts: dust collection, dust collection and dust filtration, which generally includes a string commutator motor, a centrifugal fan, a dust filter (bag) and a dust collection accessory. Generally, the power of vacuum cleaners is 400-1000w or higher, and the power of portable vacuum cleaners is generally 250w and below. The vacuum cleaner removes dust, mainly because it has an electric exhaust fan mounted on its "head".

There is a wind impeller on the rotating shaft of the exhaust fan, after the power is on, the exhaust fan will produce a higher suction swimming and pressure at a speed of 500 revolutions per second, and the air is discharged at high speed under the suction and pressure of the sacred rock, and the air of the suction part of the front end of the fan continuously replenishes the air in the fan, resulting in an instantaneous vacuum inside the vacuum cleaner, and a negative pressure difference is formed with the outside atmospheric pressure, and under the action of this pressure difference, the air containing dust is inhaled. Dust and other debris enter the dust filter bag through carpet or floor brushes, long pipes, elbows, hoses, and hose joints in turn, and dust and other debris are trapped in the dust bag, and the air is purified by the filter sheet, and then discharged from the tail of the body.
