Description
Technical Field
The utility model relates to an air purification field, concretely relates to ultraviolet and compound nanometer silver disinfect and remove haze air purification device.
Background
The air purification device is also called as an air cleaner, an air cleaner and a purification device, is a product capable of adsorbing, decomposing or converting various air pollutants and effectively improving the air cleanliness, and is mainly divided into household, commercial, industrial and building products; there are many different technologies and media in air purification devices that enable it to provide clean and safe air to users.
In the prior art, the air purification device is named as an air purification device under the patent number of 202792313U, the air purification device can be used in different sections according to the space, namely the size of a room, one of the small rooms can be opened, three rooms can work independently without mutual interference, if one of the small rooms is broken, the other two rooms can be used continuously, but the manufacturing cost is high, and disinfection and sterilization cannot be carried out.
The existing air purification device is mostly of a composite type, namely, a plurality of purification technologies and material media are adopted at the same time. The existing air purification device does not have a filter screen and a sterilization function, even if the existing air purification device has the sterilization function, the ultraviolet lamp tube is simply used for sterilization, and the publication No. CN206449773U discloses an intelligent sterilization air purification device, an ultraviolet sterilization lamp is arranged in a lamp trough, and a miniature electrostatic dust collector is arranged in a storage trough, but the intelligent sterilization air purification device has a complex structure, particularly has electrostatic dust collection, so that the intelligent sterilization air purification device is not suitable for an air purifier.
Present air purification device filter core is thick, and is complicated moreover, and the suction fan resistance is big, and is not energy-conserving, and the authorization notice number CN203790331U, its technical scheme does air filter equipment includes in proper order and just imitates filter screen, HEPA filter screen and the adjacent active carbon filter screen of catalyzing the filter screen adjacent with the casing protecgulum, just imitate filter screen, HEPA filter screen and active carbon filter screen and stack gradually, and the filter screen number of piles is too much, and active carbon in addition, ventilation resistance is very big, and is impractical, and configuration suction fan power is big, and the energy consumption is high, must improve.
The nano silver wire has no toxicity, no drug resistance and wide bactericidal effect; and the nano silver has good biocompatibility, can promote wound healing, cell growth and repair, and has no stimulation to skin. Therefore, the nano silver antibacterial material is widely applied to the fields of functional coatings, textile fibers, food, daily chemicals, medical treatment and the like at present, has a very wide market prospect, and gradually becomes a hot spot of industrial research. The method is mainly realized by the following two ways:
(1) and (5) contact sterilization reaction. The cell membrane of the bacteria has negative charges, and silver ions can be adsorbed on the surface of the cell membrane of the bacteria by virtue of coulomb force and combined with membrane protein, so that the structure of the bacteria is changed and the bacteria is damaged. In addition, silver ions can further penetrate cell walls to enter bacteria, so that the activity of cell synthetase is damaged, and cells lose division and proliferation capacity and die. In addition, silver ions can also destroy the electron and mass transport systems of bacteria and microorganisms. After the sterilization is finished, the silver ions are dissociated from the thalli, and the sterilization activity is repeatedly carried out, so that the bacteria are killed in a circulating and reciprocating manner, and the durable antibacterial effect can be maintained.
(2) Catalytic sterilization. Under the action of light, the electrons of the nano silver are excited by the light, so that oxygen in water or air is activated in a catalytic manner, and hydroxyl radicals and negative oxygen ions are generated. The hydroxyl free radical and the negative oxygen ion have strong bactericidal action, can destroy the multiplication capacity of bacteria in a short time and accelerate the apoptosis speed, thereby achieving the aim of antibiosis.
From the above situation, it is known that a single nano silver wire has a very poor sterilization effect, and is difficult to achieve an application effect, which is also a problem that nano silver sterilization cannot be well applied, and how to obtain more silver ions and perform more effective sterilization, for example, ultraviolet irradiation is adopted to excite simple substance silver to release electrons to form silver ions, is an effective method. If the ultraviolet light and the nano silver wire can be used for complementary sterilization and disinfection, the ultraviolet light and the nano silver wire can be a good choice.
