When the air around the cover body needs to be purified, the cover body 1 and the friction part 2 are rubbed to form a Maxwell displacement electric field, electrostatic attraction is generated on the surface of the cover body 1, pollution particulate matters such as PM10, PM2.5 and PM1.0 in the air can be adsorbed, and the purpose of purifying the air is achieved.
Because the cover body provided by the embodiment of the invention can have a good purification effect only by maintaining a stable static state after the friction between the cover body and the friction part, an electret is introduced into the construction material of the cover body.
The material from which the mask body is constructed may be selected from one or more of the following: cloth, a polymer film, a coating and conductive adhesive.
When cloth and polymer film, coating or conducting resin have been chooseed for use simultaneously to the cover body, can coat polymer film, coating or conducting resin on the surface of cloth to improve the performance of the cover body, thereby the contaminated particle thing in the air-purifying that can be better.
The cloth can be textile or silk fabric, etc. For example, the material comprising the silk fabric may be selected from one or more of the following: yarns, strands, silks, spins, chiffons, crepes, brocade, satin, snuff, kudzu, wool, velour, silk and composites thereof, while the material constituting the textile may be selected from one or more of the following: cotton cloth, linen, silk, wool, leather, chemical fiber, blended spinning, cotton yarn, bamboo charcoal fiber and compound thereof.

The composition and ratio of each substance in the composite composed of the silver powder conductive paste, the copper powder conductive paste, or the carbon black conductive paste may be set arbitrarily.
In addition, the actual material of the hood body is not limited to the above limitations, and can be set by those skilled in the art according to the actual requirements of the product, for example, the hood body of the car hood needs to be waterproof and sun-proof, the fly-proof hood needs to be breathable, and the helmet hood needs to reduce the light reflection of the helmet.
In addition to the kind of material constituting the cover body affecting the performance of the cover body, the layer structure of the cover body itself affects the performance of the cover body. For example, the mask body may be constructed from one or more layers of material, and where multiple layers of material are employed to construct the mask body, the multiple layers of material may be the same material or different materials. And is preferably made of multiple layers of different materials in order to improve the electrostatic performance of the shield.
When the cover body is in a multilayer structure, a certain gap can be reserved between the multiple layers, and in the using process, except that the outer surface of the cover body can rub against the friction part, the opposite surfaces of the multiple layers can rub against each other to generate static charges and form an electrostatic field.
The technical solution provided by the embodiment of the present invention is explained in detail by taking a cover body with a two-layer structure as an example, and the schematic diagrams thereof are shown in fig. 3A to 3C. Fig. 3A shows the double-layered cover in a rest state, fig. 3B shows the double-layered cover in a contact state, and fig. 3C shows the double-layered cover in a separated state.
Specifically, when the cover provided by the embodiment of the present invention is used to purify air, the cover body and the friction component may be rubbed first, and the first cover structure layer 3 and the second cover structure layer 4 in the rubbed double-layer cover are positively charged and negatively charged, as shown in fig. 3C.
For the mask body, the specific electrical property of each layer of the mask body is determined by the difference of the electron gaining and losing capabilities of the materials constituting the mask body.
For a single layer, the single layer cover body is rubbed with the friction part, the single layer cover body can be charged with positive electricity or negative electricity, and only the intensity of the electrostatic field formed by the double layer cover body is higher than that formed by the single layer cover body, so that more particles can be adsorbed, and the air purification capacity is better.
The cover body provided by the embodiment of the invention can be used as a vehicle cover, a ship cover, a helmet cover, an air conditioner cover, a curtain and the like, and the cover body material, the structure, the size, the shape and the like of the cover body for forming the cover body can be adjusted according to the function of the cover body.
In addition, the invention also provides a carrier 5, and the carrier carries the cover body. Typically, the carrier 5 will be located inside the housing, so that the housing provided by the present invention can be used to purify the air surrounding the carrier from particulate matter. For example, the carrier may be a car, a boat, a bed, a helmet, an air conditioner, a window, etc., and any object to be covered may be the carrier, and the baby carriage cover in fig. 4, the carrier 5 is a baby carriage, and the cover body 1 may completely cover the whole baby carriage.
Preferably, the carrier 5 can be connected with the cover body to form a closed space capable of ventilating, the particulate matters in the air outside the cover body can be accumulated or adsorbed on the outer surface of the cover body and can not enter the inside of the cover body, and the particulate matters in the air inside the cover body can be adsorbed on the inner surface of the cover body, so that the structure can achieve the optimal purification effect.
In one embodiment, the material of the cover is slightly rubbed to see that the electricity generated by the rubbing can easily light a 1W incandescent lamp (shown in FIG. 5), wherein a and c are the states of the incandescent lamp when the material is not rubbed, and b and d are the states of the incandescent lamp when the material is rubbed. This more intuitively demonstrates the strength of the electric field and the magnitude of the electric charge generated when friction occurs with a suitable friction material.
Meanwhile, the laser dust particle counter is used for detecting the specific content of PM10, PM2.5, PM1.0 and PM0.3 in the cover body along with the change of time in real time (fig. 6 and 7), the cover body for detection is of a double-layer structure, the cover body of the inner layer is made of cotton cloth type nylon silk with good air permeability, and the other layer of the cover body is made of nylon materials. As can be seen from the figure, after purification is carried out for 10min, the contents of PM10, PM2.5, PM1.0 and PM0.3 in the cover body are rapidly reduced, and after purification is carried out for 30min, the air level in the cover body is changed to be one level, and the air quality is excellent.
In addition, the cover body of the invention also entrusts the Beijing Tian Heng integrity environment evaluation center and the Beijing environment quality detection center by environment construction to detect the solid particles (PM2.5) in the air in the double-layer cover body and passes the quality certification. The certification result of the environment quality detection center of Beijing environmental building shows that after the solid particles (PM2.5) in the purified air are removed for 4 hours, the removal rate of the PM2.5 is as high as 99.5%, the air level in the cover body is first grade, and the air quality is excellent (figure 8); the certification result of the beijing tiancheng honesty environment evaluation center shows that the removal rate of the solid particulate matters (PM2.5) in the purified air is up to 98.5% after 30min, 90min and 180min by using the cover body, the air grade in the cover body is one grade, and the best air quality is excellent (figure 9).
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.
