[0002] A car vacuum cleaner is a vacuum cleaner that is placed in a car for use. When in use, the fan impeller of the car vacuum cleaner is driven at high speed by the motor to discharge the air in the impeller from the fan at high speed, and at the same time, the air in the dust suction part is continuously replenished into the fan, thus forming a higher pressure difference with the outside world. The dust and dirt in the suction nozzle are sucked into the dust suction part along with the air, and filtered through the filter to collect the dust and dirt. Moreover, when using a vacuum cleaner, you should not point the nozzle at the seat and suck violently, but blow away the dirt first and then suck it. The dust stuck on the car can be sucked up by the vacuum cleaner.
