No-clean hypa for vacuum cleaner

Abstract

The invention discloses a no-clean HEPA for a dust collector. The no-clean HEPA comprises two glass fiber layers and a modified fiber layer located between the two glass fiber layers. The modified fiber layer comprises, by weight, 10-100 parts of ethylene-amylene-vinyl acetate copolymer fiber and 10-50 parts of carbon fiber. According to the scheme, the structure of a conventional HEPA is improved, the two layers of glass fibers serve as the base layer, the novel modified layer is arranged in the middle, due to the introduction of the ethylene-amylene-vinyl acetate copolymer fiber and the carbon fiber, the filtering performance of the HEPA is improved, the air resistance of the HEPA is reduced, meanwhile, by means of the introduced modified layer, the flowing stability of airflow in an air channel of the dust collector can be effectively improved, the dust filtering efficiency can be obviously improved, and important components in the dust collector are protected against corrosion of dust; in addition, due to the introduction of amylene in the thylene-amylene-vinyl acetate copolymer fiber, the dust accumulation resisting capability of the HEPA is improved, and the HEPA has the no-clean function.

Description

technical field [0001] The invention relates to a filter material, in particular to a no-cleaning hypa for a vacuum cleaner. Background technique [0002] Haipa is the transliteration of HEPA. HEPA is a kind of high-efficiency filter paper material, which can filter fine particles in the air and reduce secondary pollution. As we all know, Hypa is a very important high-frequency component in vacuum cleaners. However, due to factors such as cost control, various manufacturers are slow in the development of more high-quality and efficient Hypa. However, the existing Hypa is in After using for a period of time, it is prone to clogging, resulting in poor exhaust air of the vacuum cleaner, causing the temperature of the motor to rise, which seriously affects the life of the motor; or, some dust bags have good air exhaust effect, but the filter effect on dust is not good, resulting in Under the action of strong wind, the fine dust passes through the dust bag and is discharged from...

As we all know, Hypa is a very important high-frequency component in vacuum cleaners. However, due to factors such as cost control, various manufacturers are slow in the development of more high-quality and efficient Hypa. However, the existing Hypa is in After using for a period of time, it is prone to clogging, resulting in poor exhaust air of the vacuum cleaner, causing the temperature of the motor to rise, which seriously affects the life of the motor; or, some dust bags have good air exhaust effect, but the filter effect on dust is not good, resulting in Under the action of strong wind, the fine dust passes through the dust bag and is discharged from the vacuum cleaner, thus causing secondary pollution to the indoor environment and seriously affecting the respiratory health of the human body.

At the same time, Hypa with poor filtering effect will also affect the working environment of the motor, causing fine dust to penetrate into the motor, thus seriously affecting the normal operation of the motor
