The basic structure of the vacuum cleaner is divided into five parts by function: 1. Power part: vacuum cleaner motor and governor. The governor is divided into manual control and machine control. Motor: There are copper Wire motor and aluminum wire motor. The copper wire motor has the advantages of high temperature resistance, long life, long single operation time, etc., but the price is higher than that of the aluminum wire; Aluminum wire motor has the characteristics of low price, but the temperature resistance is poor, the melting point is low, and the life is not as long as the copper wire. Governor: Manual control is generally damper adjustment (pictured); The machine control is a power-type handheld button or infrared adjustment. 2. Filtration system: dust bag, front filter, and rear filter. According to different filter materials: paper, cloth, SMS, Haipa (HEPA high efficiency filter material). 3. Functional part: Retractable line mechanism, dust full indicator, button or slide switch. 4. Protection measures: dust bag protection, high vacuum protection, anti-interference protection (soft start), overheat protection, anti-static protection. 5. Accessories: handle and hose, nozzle, floor brush, flat suction, round brush, bed sheet brush, sofa suction, hook, strap. 1. Principle of vacuuming. The fan impeller of the vacuum cleaner drives the air in the impeller to the fan at a high speed under the high-speed driving of the motor, and at the same time, the air in the dust collecting portion is continuously replenished into the fan. This may form a higher pressure difference with the outside world. The dust and dirt of the nozzle are sucked into the dust-collecting part with the air, and leaked through the leaker to collect dust and dirt in the dust cylinder. 2. The original of the vacuum cleaner. All vacuum cleaners are equipped with an assembled brush head for floor cleaning and carpet use. Suction vacuum cleaners are also equipped with a range of cleaning brushes and nozzles for cleaning corners, curtains, sofas and seams. 3. Throat: All suction vacuum cleaners are equipped with hard hoses for connecting soft hoses and accessories for cleaning. 4. Electric brush: The cleaning head of the internal vacuum cleaner is a special accessory for the hybrid vacuum cleaner. 5. Round brush head: It is also a small nozzle, which can be used for 360* rotation, which is convenient for cleaning furniture and fine mesh fabric. 6. Flat nozzle: also known as the slit nozzle, is a slender, flat hard nozzle. It is especially suitable for cleaning wall edges, radiant warmers, corners and shallow and narrow places. 7. Dust brush: Made of long, soft bristles, suitable for cleaning curtains, walls, etc. The vacuum cleaner is mainly composed of dusting, vacuuming and dust filtering. It generally includes a series commutator motor, a centrifugal fan, a dust filter (bag) and a vacuum attachment. Generally, the power of the vacuum cleaner is 400-1000 W or higher, and the power of the portable vacuum cleaner is generally 250 W or less. The vacuum cleaner can remove dust mainly because its "head" is equipped with an electric blower. There is a wind impeller on the rotating shaft of the exhaust fan. After the power is turned on, the air extracting machine generates a strong suction force and pressure at a speed of 500 revolutions per second. Under the action of suction and pressure, the air is discharged at a high speed, and the air in the vacuum part of the front end of the fan is continuously The air in the fan is replenished, so that an instantaneous vacuum is generated inside the vacuum cleaner, and a negative pressure difference is formed with the external atmospheric pressure, and the dust-containing air is sucked under the pressure difference. Dust and other debris enter the dust filter bag through carpet or floor brush, long joint pipe, elbow, hose and hose joint. Dust and other debris are retained in the dust filter bag. After the air is purified by the filter, it is discharged from the tail of the body. Aluminum Expanded Metal Mesh,curtain Wall,House Ceiling Shunyuan Wire Mesh Co., Ltd. , http://www.xawiremesh.com
