Simply talk about the working principles of different vacuum cleaners:

1. Dust bag type

The working principle of the dust bag type is very simple: the motor is running to exhaust air, (1)A dust bag is used to collect the dirt in the front;(2)Filter cotton is added in the middle to protect the motor; 3. There is no dust in the air to the room.

(Is this also called high-end? Some manufacturers are really stingy, just one more filter cotton, the cost is more than 2 cents. The service is in place)

While vacuuming and exhausting the dust, no one can bear this.

The advantage of this method is that it does not need to be cleaned. After the dust bag is full, throw away the bag together to ensure that the other parts of the machine are clean. You only need to clean the dust bag. It is very convenient. The dust bag is not expensive. 30 one. Can be used for one or two months.

However, the requirements for the quality of the dust bag are relatively high. While ensuring the permeability, the dust cannot be leaked out. The motor is followed by the motor. If the dust leakage is serious, the motor will smoke and be scrapped like my first vacuum cleaner.

The first one I used is the dust bag style. I was dissatisfied with several models halfway through, and finally used Miele's dust bag style and pushed it for a lifetime.

2. Vacuum

The vacuum cleaner, through aerodynamics, makes the dust contaminated in the dust bucket circle to achieve the purpose of temporary preservation. This method is very clever, eliminating the resistance of the dust bag and making the suction efficiency higher.

Although most of the dust rotates in the barrel, some of it will still be sucked to the rear. Therefore, in the vacuum machine, the filter used to protect the motor has many layers (the layer is not enough, and it is directly in contact with the dust, which is too dangerous) . A filter cotton will also be added behind the motor to ensure that the air blown out is clean enough.

This construction principle determines that the vacuum machine needs to empty the dust in the barrel diligently, try to avoid the pressure of the filter and the motor, so it is generally sucked once and then poured.

The centrifugal force separates fine dust and reduces the pressure on the subsequent filter. The better the route design, the lower the pressure on the filter.

The representative brand of this method is Dyson. Their home has made meticulous air rotation routes. The well-known multi-cone cyclone integrated system. In the products after V10, after 1 week of use, the filter is not very dirty.

3. Roller head, straight suction head

This is not the body of the machine, but the difference between the suction head

For example, the Dyson brand generally likes to use a drum type suction head for sucking the floor. There is a motor in the drum. It’s too close to breathe in.

Another type of floor suction, which represents the brand of Miele, is purely direct suction, like a tornado, you can suck in whatever you encounter, the surrounding ones can also be sucked in.
