Hereinafter, the beneficial effects of the negative pressure suction air purifier and the air purification method provided by the present invention will be described.

The negative pressure suction air purifier and air purification method provided by the present invention can: 1) remove bacteria and viruses in the air (including but not limited to bacteria and new coronaviruses, destroy their protein structure and ribonucleic acid to make them inactive And dissemination); 2) remove harmful chemical substances (disinfectant aerosols and others: such as formaldehyde, benzene and xylene, etc.) generated by the air and the purifier equipment itself; 3) remove the air and the purifier equipment itself Inhalable particulate matter (PM2.5 and PM3.0, etc.); 4) can effectively adsorb the "six categories of eleven poisons" of chemical weapons; 5) remove odors (VOC: life odors, tobacco, human and laboratory animals Body odor, etc.); 6) No secondary dust pollution (activated carbon guarantees 100% adsorption efficiency and no dust during the work process); 7) No secondary chemical pollution (disinfectant aerosol is adsorbed: purification Purification). In short, the indoor air filtered and adsorbed by the negative pressure suction air purifier and the air purification method provided by the present invention, the bacteria, viruses, the outside world, and the chemical substance aerosol and inhalable particles produced by the purifier device itself are harmful. Substances will be efficiently removed at the same time until they are completely removed, effectively cutting off the air transmission route of viruses and harmful chemicals, and at the same time not generating secondary dust and chemical pollution.

The negative pressure suction air purifier and air purification method provided by the present invention have a wide application range and can be flexibly applied to: 1) biological laboratories and other laboratories that require air purification protection measures; 2) ICU wards; 3) breathing Department and Infectious Diseases; 4) Hospital waiting areas and other medical public areas that require isolation measures; 5) Public places, such as buses, subways, shopping malls, restaurants and cinemas, etc.; 6) Decoration and daily routines (new decoration, new Furniture and members are sick); 7) Private cars (passengers with second-hand smoke and uncertain health status); 8) Other fixed enclosed spaces with crowds or living bodies; 9) Movable temporary safe houses, rest rooms, workstations or Waiting room; 10) mobile enclosed spaces such as airplanes and high-speed railways; 11) fire smoke, secondary harmful aerosols and inhalable particulates in fire fighting; 12) chemical industry, such as daily production, storage and active leakage protection; 13) Purification of industrial applications and production environments to control the safety criticality of environmental concentration; 14) epidemic prevention; 15) military applications (biochemical defense equipment: fortifications, vehicles, submarines and individual protection); 16) national material reserves; 17) emergency shelters and many more.

The negative pressure suction air purifier and the air purification method provided by the present invention are extremely easy to obtain raw materials, simple to manufacture, and extremely easy to produce and promote; comprehensive purification and safe and reliable use; the overall device is easy to carry and transport, and is simple to install and combine. It is easy to teach and use skillfully, with efficient and thorough functions; invalid air purification units and boxes can be recycled for harmless treatment without causing secondary pollution, and can also be recycled and reused, low-carbon, energy-saving and environmentally friendly.

The negative pressure suction type air purifier and the air purification method provided by the present invention are safer and more effective than the disinfection sprayer by the negative pressure suction type design: the air containing harmful aerosol components can be sucked into the medicament box encapsulating the "high concentration disinfectant" ( In the box), it can effectively destroy the transmissibility of bacteria and viruses without causing secondary harm to the human body and the environment. The sprayer with relatively spray function and other patents and technologies: the low concentration of the disinfectant sprayed into the air will have poor sterilization and detoxification effects; when the concentration of the sprayed disinfectant is high enough to sterilize and detoxify, the human body cannot bear the high-concentration disinfectant. Aerosols or residues are bound to be poisoned and cause continuous pollution to the environment (human poisoning and injury precede the complete removal of bacteria and viruses).

The negative pressure suction air purifier and the air purification method provided by the present invention, 1) independent replacement of the medicament box (box body 120) can ensure the adsorption effect and reduce unnecessary consumption and consume a large amount of medicament box (box 120) than the entire replacement. Body 120) can be added independently or even in double parts of the kit (box 120) unit; 2) For different concentrations and different types of environmental pollution sources, targeted adsorption kits (box 120) can be added independently at any time ), which is more convenient and scientific than other patented and technical pre-installed fixed designs (must be replaced and may not be applicable); 3) For environmental pollution of complex components (more than two pollutants), targeted agents can be optionally installed The box (box 120) can correspond one to one, and it can avoid the contradiction of the medicine box (box 120) with the pollution source or produce new and more serious chemical reaction consequences. It is better than other patents and technical pre-installed fixed designs. Flexible, for example, when the adsorbed gas (such as toilet cleaner) and the medicament box (box 120) (such as 84 disinfectant) may produce toxic gas, the medicament box (box 120) unit can be removed immediately , Replace other adsorbent cartridge units to avoid secondary damage; 4) The adsorbent material is not limited to a certain physical state (gas, liquid and solid), as long as it can be loaded into the cartridge (box 120) and the airflow can pass through. , Better than other patents and technical fixed state (liquid or solid) design; 5) For complex polluted environments (dusty, warm, wet, or dry, etc.), it can be guaranteed by changing the order of the cartridge (box 120) The best adsorption effect; other patents and technologies are impossible to achieve; 6) purification of purification and treatment of treatment; and other patents and technologies do not have the purification and treatment functions of the latter link against the previous link; 7) Activated carbon The technology has a wide range of applications and extended applications, which is also an important reason why the present invention and equipment can be applied to various fields (even military defense). This is also the fundamental feature that other patents and technologies can only be limited to civilian use in limited scenarios; 8) Box card Button installation, no need to dismantle the whole machine; other patented and technical fixed design is to seal the filter element in the inner shell of large equipment and airtight pressure tank, which must be disassembled and replaced by professionals and ensure that the tank body is airtight and does not lose pressure before it can work normally 9) The installation of the medicament box can be completed anytime and anywhere, and can be operated without the need for professionals; and other patents and technical fixed types are installed in specific places in specific places (such as: the wind tunnel of the central air-conditioning in the ceiling), so disassembly and assembly It is inconvenient and requires professional operation.

Above, the preferred embodiments of the present invention have been described in detail. However, the present invention is not limited to the foregoing embodiments, but can be implemented in various forms. The embodiments disclosed in this specification are provided only to complete the disclosure of the present invention, so that those of ordinary skill in the art can fully understand the scope of the present invention.
