What is a vacuum cleaner? How many types of vacuum cleaners are there?

The original vacuum cleaner was a machine that sucked dirt from carpets to living room floors and used air pressure differences to clean them. It is convenient to clean every corner of the room.wet dry stick vacuum When cleaning a space, plug the cord into a wall outlet, move to the desired location and vacuum. The structure consists of the intake duct, engine, rotor, filter, dust box and exhaust device. Its action process is as follows. A rectifier sub-motor is used to rotate the rotating body more than 10,000 times to form a vacuum state inside and inhale dust or garbage. The inhaled dust, scum, etc. are filtered in the filter, and the air is discharged through the exhaust pipe. The design of the suction inlet also varies depending on the location of use, making it very convenient to use.

The types of vacuum cleaners that use dust bags include: horizontal, vertical, portable, canister,wet and dry vacuum cleaner for home etc. The horizontal vacuum cleaner is by far the most popular type of vacuum cleaner in Harbin and consists of a main unit, a suction tube, a pipe and a brush. It can pick up dust from surfaces and clean every corner, but it is difficult to remove dust from carpets. Upright vacuum cleaners are mainly used in the United States and Europe, where carpets are often used. Thanks to the rotating brush, dust on the carpet can also be cleaned. Handheld vacuum cleaners are lightweight and suitable for use on desks, lathes, and suit vacuums, but they have a smaller dust collection capacity and limited use time due to the use of batteries. However, with the improvement of technology and battery performance, handheld vacuum cleaners have developed rapidly. The diversification of performance and accessories has basically met the requirements of general household use. The design of products has also become more and more sophisticated with the changes of the times. The handheld vacuum cleaner is equipped with a variety of accessories, a convenient charging base and a battery remaining display function to meet the needs of various occasions. Cylindrical vacuum cleaners have a large dust collection capacity and can be used at home, but are mainly used in offices or shops. The disadvantages are that they are large and noisy. Up to now, with the improvement of technology, anti-noise design has greatly reduced engine noise.

The centrifugal separation method was invented to improve on the main shortcoming of bag vacuum cleaners, which reduce suction power with use. Using the principle of centrifugal force to allow dust to settle, the air can be discharged through a filter, which has the advantages of economical and continuous suction and filtering of fine dust.

Later, the vacuum cleaner was invented, which can perform both vacuum cleaning and water cleaning and filtration. Clean the sprayed water through the brush at the bottom and inhale the dust, and then put it into the bucket on the main machine. After the dust enters the water, the air is taken in through the motor and discharged through the filter. It can reduce floating dust, etc., and has air purification function.

With the development of science and technology, using battery power, various sensors such as ground sensors, cliff sensors, tire drop sensors, etc. are installed, as well as sensors for sensing obstacles, and autonomously use programs or wireless control to move on the ground and clear the ground. Robot vacuum cleaner for dust or fine dust was invented.
