Low wind resistance hypa for vacuum cleaner

Abstract

This case discloses a low wind resistance Hypa for a vacuum cleaner, comprising two glass fiber layers and a modified fiber layer located between the two glass fiber layers, wherein the modified fiber layer includes the following materials in parts by weight: propylene- 10-100 parts by weight of styrene-butadiene copolymer fiber filaments and 10-50 parts by weight of carbon fiber filaments. In this case, the structure of conventional Hypa is improved, with double-layer glass fiber filaments as the base layer, and a new modified layer is set up in the middle. By introducing propylene-styrene-butadiene copolymer filaments and carbon fiber filaments, the The filtration performance of Hypa is improved, and the wind resistance of Hypa is reduced. At the same time, due to the modification of styrene in the propylene-styrene-butadiene copolymer fiber filament, the stability of the air flow in the air duct of the vacuum cleaner is effectively improved, and the airflow is significantly improved. It improves the dust filtration rate of the vacuum cleaner and can protect the important parts in the vacuum cleaner from dust erosion.

Description

technical field [0001] The invention relates to a filter material, in particular to a low wind resistance Hypa for a vacuum cleaner. Background technique [0002] Haipa is the transliteration of HEPA. HEPA is a kind of high-efficiency filter paper, 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 ...

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
