Problems solved by technology

Among the commonly used types of masks, professional protective masks are the most effective for protecting PM2.5, such as common N95 and N90 masks, but the airtight effect of these masks is so good that the amount of air that can pass through is also limited. Do not wear it for a long time, especially not suitable for children, the elderly or people with poor respiratory system function

Abstract

The invention relates to essential oil microspheres for a mouth-muffle filter sheet and a preparation method of the essential oil microspheres. The essential oil microspheres for the mouth-muffle filter sheet are made of sodium alginate or gelatin, and multiple types of common plant essential oil are wrapped in the microspheres. The essential oil microspheres are simple, convenient and feasible in preparation process, relatively low in cost, and applicable to industrial large-scale production. The essential oil microspheres provided by the invention are placed in the mouth-muffle filter sheet, can emit fragrance, and have the effects of refreshing the mind and restoring the consciousness and being cooling and refreshing.

Description

technical field [0001] The invention belongs to the technical field of microspheres, and relates to an essential oil microsphere used for mask filters and a preparation method thereof. Background technique [0002] A mask is a sanitary product, generally refers to a device worn on the mouth and nose to filter the air entering the mouth and nose to block harmful gases, odors, and droplets from entering and exiting the wearer's mouth and nose, made of gauze or paper. Masks have a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent, wearing a mask has a very good effect when working in a polluted environment such as dust. Due to the development of industry and the popularization of automobiles, the air quality is declining year by year, especially during the annual heating period. Due to the use of coal burning, a large amount of harmful substances are emitted into the air, especially PM2.5 particles that have attracted pub...
