How Vacuum Cleaner Works

The car vacuum cleaners work by creating a pressure difference: the motor drives the wing to rotate at high speed, pushing the air in the casing outward, turning the inside into a low-pressure area. In order to find a balance, the high-pressure air outside will be forced into the dust suction port like being pulled, and the dust will be brought in by the way. The core logic lies in the “airflow path”. As long as you keep this passage smooth-from the suction nozzle, hose, all the way to the HEPA filter to the exhaust port, the machine will remain strong.

How Does Suction Come About

Vacuum cleaner belly that set of motor and fan combination, is its heart. As soon as the engine is turned on, the motor rotates rapidly to drive the fan blades, throwing the internal air to the exhaust port like an exhaust fan. At this time, the air pressure inside the machine is instantly reduced, forming a sense of vacuum. According to the common sense of physics, the air always runs to the place where the pressure is low, so the external atmospheric pressure will push the dust into the suction port. This is the fundamental reason why it can suck the debris out of the gap.

Vacuum Cleaner Filtration Mechanism

Air and dust are mixed together, and subsequent treatment is critical. At present, the mainstream on the market on two ways:

Cyclone separation: high-end models rely on centrifugal force. The air is whipped around in the conical chamber, the dust is thrown to the pipe wall due to the inertia of gravity, and the clean air slips away from the middle.

Physical Interception (HEPA Filter): No matter how you separate it, you have to pass this level in the end. HEPA filters are designed to deal with tiny allergens and fine ash. The quality of the filter directly determines whether the wind discharged is 1 musty, so this part must be paid attention.

Regular Maintenance Of Vacuum Cleaners

Many people think that if the suction is small, the motor is broken. In fact, there is no need to change it in a hurry. Vacuum cleaners rely on airflow circulation, and any bit of blockage will collapse the pressure difference. If you want to keep your car as clean as if you just washed it, pay more attention to these 3 points:

• Check the suction nozzle and hose: this is the most likely place to get stuck. Sometimes it’s just a small piece of stone or paper, and the suction comes back immediately.
• Clean or replace the filter element: Many people ignore the filter element. If the filter element accumulates a thick layer of ash, the air flow will be blocked, and the motor will work hard to inhale, which will not only cost electricity, but also damage the motor for a long time.
• Check the exhaust port: make sure there is no dust accumulation in the exhaust port, so that the air can be discharged smoothly.

In the final analysis, keeping the gas path open is king. Just make sure that the entire path from the suction port to the exhaust port is clean and unimpeded, even if it is a difficult interior stain, the machine in your hand can handle it with ease.
