The main components of vacuum cleaners are vacuum pumps, dust bags, hoses and exhaust fans. Its working principle is that the exhaust fan in the vacuum cleaner is under the action of electric current, which is what we usually say when the exhaust fan rotates after the power is turned on. At this time, the inside of the vacuum cleaner is in a vacuum state.
Since the vacuum cleaner is in a vacuum state, the air pressure inside is lower than the air pressure outside. At this time, dust and particles on the ground will be forced into the stick mop vacuum by the atmospheric pressure, that is, sucked in. After the filtering effect of the dust bag, the garbage will be left in the dust bag. Just turn on the vacuum cleaner and easily hold the vacuum hole to use it.
1. There is a big difference between the two. First of all, the quality is different. The quality of the vacuum cleaner is guaranteed and the dust collection effect is good. The quality of ordinary household vacuum cleaners is not guaranteed, and the effect is not as good as vacuum, but ordinary vacuum cleaners are cheaper, and vacuum cleaners are more expensive.
2. Vacuum cleaner: There is an electric exhaust fan inside the vacuum cleaner, which can form a vacuum through high-speed operation, and the pressure will be much lower than the outside air pressure. Under the action of a relatively large air pressure gap, the dust on the ground is sucked into the barrel.
3. Ordinary dust cleaner for home: The motor of the vacuum cleaner rotates at a high speed, sucking in air from the suction port, and generating a vacuum. Dust is sucked in through the brush handle, hose, etc., and enters the motor through the filter.
1. Type of vacuum cleaner
First of all, when purchasing a vacuum cleaner, pay attention to the type of vacuum cleaner. Common vacuum cleaners on the market are divided into horizontal, vertical and hand-held types. Hand-held and vertical types are more convenient to use. When using a horizontal vacuum cleaner, both the wire bondage and the socket must be considered. It is best to choose a wireless vacuum cleaner if possible, and its use is not limited by space. And the robot vacuum cleaner is a better choice.
2. Suction power
When purchasing a vacuum cleaner, pay attention to its suction power. The suction power is the heart of the vacuum cleaner, and only a good motor has a strong suction power.
3. Differentiation between wet and dry
When purchasing a vacuum cleaner, it depends on the choice of the area of use. Some vacuum cleaners can only absorb dust, while others can dry and wet at the same time. It is best to choose a vacuum cleaner with both dry and wet functions.
4. Cleaning ability
Finally, it depends on the cleaning power of the vacuum cleaner, which not only refers to the dust collection effect, but also includes the internal dust removal. Some vacuum cleaners are more strenuous to remove internal dust. In addition, some vacuum cleaners can not only suck off the dust on the surface, but also can suck off the dust on the sofa, table and chair by changing the rotating head.
