What are your knowledge of vacuum cleaners?

Vacuum cleaner introduction

The air in the impeller of the fan is discharged at a very high speed, and an instantaneous vacuum is formed in the vacuum cleaner, forming a certain negative pressure difference with the outside world, and the cleared material is sucked into the vacuum cleaner under the action of the negative pressure difference, thus achieving the purpose of cleaning and vacuuming.

Vacuum cleaner types

Vertical vacuum cleaners, horizontal vacuum cleaners, and portable vacuum cleaners rechargeable handheld vacuum cleanercan be classified based on their shape. The majority of vertical vacuum cleaners have a cylindrical shape. The spindle of the vacuum motor is parallel to the ground on horizontal vacuum cleaners, and the motor, fan, and vacuum section are installed in the horizontal order inside the housing.

Because of the light weight, flexibility, and limited range of use environment of portable vacuum cleaners, portable vacuum cleaners are also classified as shoulder, pole, and portable. The largest type of portable is the shoulder type, which is carried on the shoulder with a belt and is very convenient to clean the stairs with; the pole type vacuum cleaner is shaped like a pole, and the main parts such as the motor, fan, and dust extraction section are installed in the middle of the pole. It is lightweight and labor-saving, and can clean low furniture such as sofas and wall corners without bending down; the handheld type can be used directly in the hand. Its structure is very simple; generally, no hose is required, and it can be directly connected to the suction head's work. Mostly used to clean sofas, clothes, bedding, and bookcases.

It can be classified as dry vacuum cleaner, wet and dry vacuum cleaner, and carpet vacuum cleaner using functional classification. The vacuum cleaners listed above are all dry; wet and dry vacuum cleaners use a bypass type waterproof motor, and the structure is more complicated than the dry type. It can suck up liquid or multi-water foam dirt like soap and water, in addition to having the same performance and uses as dry vacuum cleaners.

The carpet vacuum cleaner is designed specifically for cleaning carpets and includes a rotating Zimmermann Kids HKbrush at the bottom known as a roller brush that brushes dust particles from the carpet. The suction power required by this vacuum cleaner can be adjusted based on the length of the carpet pile and the size of the resistance to movement when vacuuming.

What makes vacuum cleaners work?

Although there are many different types of vacuum cleaners, they all operate on the same basic principle.

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

2At the same time, the air in front of the fan in the dust-absorbing part constantly supplemented the air in the impeller, resulting in the formation of an instantaneous vacuum in the dust-absorbing part, that is, in the dust-absorbing part and the external atmospheric pressure formed a fairly high negative pressure difference, and under the action of this pressure difference, the garbage and dust near the nozzle with the air flow through the nozzle into the dust-absorbing part.

3After filtering, the garbage and dust are retained in the ash storage box in the dust-absorbing department, while the air becomes clean air after passing through the filter, then passes through the exhaust chamber, and the air outlet is discharged back into the room. The dust collection chamber can only be cleared once when it is full of garbage and dust.

The fundamental design of a vacuum cleaner

The shell, dust collecting part, vacuum cleaner accessories, motor, fan, muffler, and other components make up Jimmy Wonga vacuum cleaner. The shell is a supporting part of the vacuum cleaner that serves to protect the internal structure and ensure safety by supporting the parts of the vacuum cleaner and separating them from the outside world. The vertical vacuum cleaner's shell is divided into two sections: the upper shell and the lower shell.
