Embodiment:
The present invention will be further described with embodiment below in conjunction with the accompanying drawings:
As shown in figure 1, a kind of be applied to medical experiment computer air cleaning unit, by inlet air filtration unit 2 and bear
The two parts of ion cleaning unit 3 form, and inlet air filtration unit 2 is arranged on the air inlet of computer, and anion fine-purification unit 3 utilizes
Four screws of installation power supply are fixed at air outlet.
As shown in Fig. 2 inlet air filtration unit is by air inlet 4, carrier base 5, O-ring seal 6, HEPA (High
Efficiency particulate air Filter, high efficiency particle air filter) filter bag 7, activated charcoal strainer 8, miniature wind
Fan 9, support casing 10, sealing gasket 11, air intake amount control circuit 12 and the part of air outlet 130 composition.The filter element is arranged on meter
The air inlet of calculation machine, the air for entering cabinet is filtered.The filter element is to the filtering effect more than 0.1 micron particles thing
Rate is up to 99%.
Air inlet 4 is the unique passage that air is entered cabinet by surrounding environment.Carrier base 5 is the metal work specially processed
Part, one end are fixed on computer mainframe shell air inlet, and the other end is inserted in HEPA filter bags 7.O-ring seal 6 is rubber system
Product, standard component, the sealing for carrier base 5, HEPA filter bags 7 and support casing 10.
HEPA filter bags 7 are a kind of high efficiency particle air filters, and air can be but tiny dust, acarid, thin by HEPA
The particulates such as bacterium but can not be by it is possible thereby to thoroughly remove PM2.5 particulates, pollen, yellow sand and the virus of attachment, bacterium, the spittle
Deng.The HEPA materials that the present invention reaches more than 99% from the molecule filter efficiency for more than 0.1 micron make HEPA
Filter bag 7.The filter bag disassembly, cleaning are convenient, can still ensure that quality by 100 washings with Reusability.Activated carbon mistake
Filter screen 8 is between HEPA filter bags 7 and mini-fan 9, on support casing 10, to adsorb peculiar smell and pernicious gas.
Because the air inlet of HEPA filter bags 7 is squeezed on carrier base 5 by support casing 10 by O-ring seal 6, ensure that
Air can only be entered by the passage that air inlet 4, carrier base 5, HEPA filter bags 7, activated charcoal strainer 8 and mini-fan 9 are formed
Enter cabinet inside.
Mini-fan 9 is tightly connected support casing 10 by sealing gasket 11.Mini-fan 9 is a kind of low-noise strong blast volume direct current
Mini-fan, the rotating speed of the fan are directly proportional to supply voltage.The present invention selects below rotating speed 2000rpm, and noise is not more than
40dBA mini-fan.Support casing 10 be a tubular one end carry the mounting disc of mini-fan 9 moulding, the one of support casing 10
Hold and provide sealing joint and filtering support for HEPA filter bags 7, the other end passes through sealing gasket 11 and connects mini-fan 9.Sealing gasket
A kind of 11 rubber standard components, the sealing for mini-fan 9 and support casing 10.
Air intake amount control circuit 12 is a monolithic processor controlled intelligent cell, and the unit has two biographies of temperature and gas pressure
Sensor, on the premise of ensureing that machine loading pressure is more than environmental pressure, mini-fan is changed according to the temperature of computer CPU
9 supply voltage, so as to change air output.Because machine loading pressure is more than environmental pressure, dust can not pass through cabinet
Other gaps enter cabinet inside, and it is the unique passage that air enters cabinet thus to ensure air inlet 1.The unit also has the shape that works
State display function, single-chip microcomputer on-line measurement 9 operating current under specific supply voltage of mini-fan, according to the size of electric current,
Judge whether current filter net state is normal, when operating current reaches warning value alarm, prompting people clean HEPA mistakes in time
Filter bag 7.
As shown in figure 3, anion fine-purification unit is by protection network 14, netted high-voltage positive electrode plate 15, spray point 16, netted high pressure
Negative plate 17, anion generator 18, protective net frame 19, power switch 20 and the part of 12V power supplies plug 21 8 composition, peace
At the air outlet of computer power supply.
Wherein protection network 14 is arranged on protective net frame 19, while Chalk-dust filtering, it can be ensured that the safety of device and U.S.
See.
Netted high-voltage positive electrode plate 15 is made from one side pcb board, for welding spray point 16 and anion generator 18
High-voltage positive electrode line.Spray point 16 selects the gold-plated single connectors of 2.54mm, is welded on netted high-voltage positive electrode plate 15.The spray point
16 are placed in protective net frame 19,40mm or so distance are kept with power source protective cover, and keep hanging down with netted high voltage negative plate 17
Directly.
Netted high voltage negative plate 17 is made from the gold-plated pcb board of one side, and the high pressure for welding anion generator 18 is born
Polar curve.The high-voltage positive electrode line of anion generator 18 is connected with spray point 16 by the copper cash that covers on netted high-voltage positive electrode plate.It is negative
It is short-circuit with counter body after the netted high voltage negative plate 17 of high voltage negative line connection of ion generator 18.Anion generator 18
Rated power in below 5W, operating voltage is direct current 12V, output voltage direct current 6000V-20000V.
Protective net frame 19 is the moulding that a tubular both ends carry mounting disc, will using four screws of fixed host computer power supply
It is arranged at air outlet.The center of protective net frame 19 is installed by netted high-voltage positive electrode plate 15.One end of protective net frame 19 is fixed anti-
Protecting wire net 14, facilitate the disassembly, cleaning of protection network 14;The other end installs netted high voltage negative plate 17.12V power supplies plug 21 connects
The 12V power outlets in main frame are connect, ensure host synchronization work.
The unit enters working condition during computer operation, and the gas 22 of power supply fan discharge can only be in protective net frame 19
Pass sequentially through netted high voltage negative plate 17, spray point 16, netted high-voltage positive electrode plate 15 and protection network 14 and enter surrounding environment.
Because high direct voltage caused by anion generator 18 connects on spray point 16 and netted high voltage negative plate 17 respectively,
Form high voltage electric field between positive/negative plate, anion generator 18 exports high-pressure electrostatic during computer operation, in the He of spray point 16
The gas ion of formation high concentration between netted high voltage negative plate 17, electronegative gas ion, in the presence of electric field force, to
Positive plate motion, after reaching positive pole, releases negative electrical charge.The gas 22 of power supply fan discharge is ionized rapidly in this course, can
It is quick to kill the various microorganisms such as the virus carried in gas, bacterium, it can also be electrolysed organic peculiar smell, chemical volatile matter, dust, cigarette
The harmful substances such as mist.Filtered, cleaned gas 23 discharges protection network, can effectively improve air cleanliness, improve surrounding ring
Border, protect the health of operating personnel.
The unit is durable in use, substantially without maintenance.Power switch 20 controls the working condition of the unit.Power supply fan is arranged
The gas 22 gone out refers to the gas after being filtered by filter element.Cleaned gas 23 refers to net by filter unit and anion
Change the gas after purification unit.
Although above-mentioned the embodiment of the present invention is described with reference to accompanying drawing, model not is protected to the present invention
The limitation enclosed, one of ordinary skill in the art should be understood that on the basis of technical scheme those skilled in the art are not
Need to pay various modifications or deformation that creative work can make still within protection scope of the present invention.
