Introduction to vacuum cleaners

The motor causes the fan's impeller to rotate at high speed, causing the air in the impeller to be released at high speed. Inside the hoover, a vacuum is created, creating a negative pressure difference with the outside environment.

Different types of vacuum cleaners

They are classified into upright vacuum cleaners, horizontal hoovers, and portable hoovers based on their shape. Vertical vacuum cleaners are generally cylindrical in design. The horizontal vacuum cleaner's key feature is that the suction motor's spindle is parallel to the ground, and the motor, fan, and dust extraction portion are positioned in a horizontal order inside the housing.

Portable vacuum cleaners are distinguished by their light weight, ease of use, and limited range of applications, hence they are classified as shoulder, pole, and handheld. The shoulder hoover is the largest portable variety and is the most convenient to use since it is carried on the shoulder with a strap and may be used to clean stairs. It is light and easy to use, and may be used to clean low furniture such as sofas and corners of walls without stooping down; the handheld version can be held directly in the hand. It has a relatively basic design and, in most cases, does not need to be linked to a hose; instead, it can be simply connected to a working suction head. It is mostly used to clean sofas, clothing, and bedding, as well as bookcases.

They are classed as dry hoovers, wet and dry hoovers, and carpet hoovers based on their purpose. Wet and dry vacuum cleaners employ a bypass-type waterproof motor and have a more sophisticated structure than dry vacuum cleaners. It can suck up liquids such as soap and water or multi-water foam filth in addition to having the same qualities and functions as a dry vacuum cleaner.

The carpet hoover is designed to clean carpets and has a revolving brush at the bottom known as a roller brush that brushes dust particles off the carpet. The suction power of the vacuum can be adjusted based on the length of the carpet pile and the level of resistance to movement during vacuuming.

The operation of a vacuum cleaner

There are many different types of vacuum cleaners, but they all work on the same premise.

1 A single-phase AC/DC motor drives the fan's impeller at high speed, causing the air inside to be ejected at high speed.

At the same time, the air in the impeller is constantly replenishing the air in the front end of the fan, resulting in the production of an immediate vacuum in the dust-absorbing section, i.e. a significant negative pressure differential between the dust-absorbing part and the outside atmosphere.

3In the dust collection portion, the garbage and dust are retainedbest cordless handheld vacuum for pet hair in the ash storage box after filtering by the filter; while the air, after passing through the filter, becomes clean air and then flows through the exhaust chamber and the air outlet is re-exhausted to the room. When the dust collection chamber becomes full of trash and dust, it is cleared once.

The fundamental design of a hoover

A shell, dust collection section, hoover attachments, motor, fan, muffler, and other components comprise the hoover. The casing is a supporting element of the vacuum cleaner that protects the internal structure and ensures safety by supporting the various sections of the hoover and isolating them from the outside world. A vertical hoover's casing is separated into two parts: the upper casing and the lower casing.

The dust collection section is divided into two components: the filter and the dust collector. The dust collector, often known as the dust box, is the component of the hoover that collects dust particles. The filter is one of the hoover's key functional pieces, and it is used to filter dust and particles from the air. The filter is frequently available as circular bags, cylinders, and flat plates.

Motors that run on electricity. A hoover's electric motor is commonly utilized as a series-excited rectifier motor. This type of motor has a high rotational speed (more than 20,000r/min) under industrial frequency power supply, as well as a large torque and soft mechanical characteristics (the rotational speed rises quickly at no load and decreases when carrying a load), making it ideal for vacuum cleaner operation.

Accessories for vacuuming. Hoover accessories include dust hoses, extension tubes, nozzles, and so on; mufflers, which are frequently fitted to lessen the noise of hoovers at work; and suction adjustment devices, which are primarily accomplished by adjusting the speed of the hoover motor. The higher the motor speed, the stronger the suction power; conversely, the lower the speed, the lower the suction power; dust indicator, which is a component of the hoover used to signal if the dust collector is full of dust or the filter air condition. The dust indicator's operation is depicted in the diagram below.
