No-wash HEPA for handheld type dust collector

Abstract

The invention discloses a no-wash HEPA for a handheld type dust collector. The no-wash HEPA for the handheld type dust collector comprises a glass fiber layer, a modified fiber layer and a sponge layer, wherein the modified fiber layer comprises the following materials in parts by weight: 40 to 80 parts of propylene-vinyl acetate copolymer cellosilk and 20 to 60 parts of copper ammonia cellosilk.Through improvement of the conventional HEPA structure and the material and through introduction of the propylene-vinyl acetate copolymer cellosilk and the copper ammonia cellosilk, the filtering property of the HEPA under small psace is improved and the wind resistance of the HEPA is reduced; meanwhile, the introduced modification layer can effectively improve the flowing stability of airflow inan air flue of the dust collector, can improve the dust filtering effect and can protect a core part in a miniature dust collector; in addition, due to introduction of the propylene in the propylene-vinyl acetate copolymer cellosilk and the introduction of sisal fiber, the dust retention resistance of the HEPA is improved and the HEPA has a no-wash function.

Description

technical field [0001] The invention relates to a filter consumable for a vacuum cleaner, in particular to a non-washing Hypa for a hand-held vacuum cleaner. Background technique [0002] Haipa is the transliteration of HEPA. HEPA is a high-efficiency filter material that 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 a period of use, especially for the increasingly popular small-volume vacuum cleaners, such as hand-held vacuum cleaners, they are prone to clogging, resulting in poor ventilation 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 dust filtering effect is not go...

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 a period of use, especially for the increasingly popular small-volume vacuum cleaners, such as hand-held vacuum cleaners, they are prone to clogging, resulting in poor ventilation 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 dust filtering effect is not good, causing fine dust to pass through the dust bag and be discharged from the vacuum cleaner under the action of strong wind, thus causing secondary pollution to the indoor environment and seriously affecting human breathing. healthy

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