A bionic anti-haze mask based on the surface microstructure of four-leaf clover

Abstract

The invention provides a bionic anti-haze mask based on the surface microstructure of four-leaf clover. The bionic anti-haze mask is composed of a bionic filtering part, a supporting and covering partand ear-hooks, wherein the main boy of the supporting and covering part is bowl-shaped, the bowl rim of the supporting and covering part is inward, and a pair of ailerons extend along the two sides of the bowl rim; the two ear-hooks are respectively connected with the end parts of the ailerons on the two sides; the middle of the bowl bottom of the supporting and covering part is an empty chamber,and the inner side and the outer side of the empty chamber are both provided with inner edges; the bionic filtering part is embedded in the empty chamber and is limited in the empty chamber through the inner edges of the two sides; the bionic filtering part is composed of a shell and filter elements, and air holes are formed in the front end face and the rear end face of the shell; and the filterelements are arranged in the shell and are bionic porous nickel foam spherical particles, and the surfaces of the bionic porous nickel foam spherical particles have a ridge and scale secondary microstructure imitating the surface of the four-leaf clover. The bionic anti-haze mask can realize high intercepting and blocking efficiency for fine particulate matters, is easy for recycling after cleaning, and avoids secondary pollution and resource waste.

Description

technical field [0001] The invention belongs to the technical field of anti-haze mask design, in particular to a bionic anti-haze mask based on the surface microstructure of a four-leaf clover. Background technique [0002] At present, the problem of air pollution has caused great harm to the life and work of Chinese residents. A large amount of fine particle dust is suspended in the atmosphere, and may enter the lungs of the human body with the breathing of residents, causing a series of hazards to human health. The resulting smog and possible health problems have attracted great attention from residents. Wearing an anti-smog mask is one of the effective ways to prevent fine particles from entering the human body, and it is also a method commonly used by current residents. [0003] Existing anti-haze mask mainly has the following defects: [0004] 1. The ability of ordinary masks to absorb fine particles is limited. After a certain period of use, the adsorption of fine pa...

Problems solved by technology

[0006] 3. The fabric of the cloth mask itself has the characteristics of easy adsorption, which makes it difficult to remove the adsorbed fine particles and cause secondary pollution; in view of the disadvantage that the cloth mask is difficult to clean, the predecessors also invented disposable masks or used replacement filter elements Although it can prevent the secondary pollution of fine particles to a certain extent, it causes a waste of resources and cannot solve the disadvantages of the mask itself producing lint;

[0007] 4. Activated carbon particles are often used as adsorption materials in existing masks, but as the particle size of activated carbon particles decreases and the use time increases, activated carbon powder will be produced, and activated carbon powder will enter the user's respiratory system with breathing, which is harmful to the user's health. cause harm
