Secondly, the centrifugal fan 603 is started, air flow enters from the air inlet 502, is filtered by the HEPA filter screen 804, is sucked into the air inlet pipe 604 and is sent into the disinfection chamber 601, the water pump 605 is started, the disinfectant in the disinfectant injection box 12 is sucked into the disinfection chamber 601 through the guide pipe and is atomized and sprayed out through the atomizing nozzle 602, the atomized disinfectant fully contacts and reacts with air, the disinfection reaction rate is improved, and the disinfection effect is improved.
Secondly, start air pump 1303, air pump 1303 with the air suction dilution chamber 1302 that mixes with disinfectant in the disinfection chamber 601 in, start driving motor 1301 simultaneously, the output of driving motor 1301 passes through the shaft coupling and drives hollow pivot 1304 and rotate, the top of hollow pivot 1304 is provided with the sleeve pipe, the diluent of diluent injection box 2 inside injects the sleeve pipe through the pipe and gets into in the hollow pivot 1304 again, along with the rotation of hollow pivot 1304, disinfectant is sprayed by the inside through-hole 1306 of flabellum 1305 soon and is gone out under the centrifugal force effect, dilute the disinfectant in the air, final exhaust air disinfectant content is lower like this, alleviate the discomfort that the peculiar smell led to the fact to hospital patient simultaneously, reduce the harm to the human body.
Finally, the air that the dilution finishes rises to retort room 3's inside through the pipe, and ultraviolet lamp 4 in retort room 3 carries out the secondary disinfection of disinfecting to the air, reduces the bacterium that the air probably is infected with when 1 inside flows of equipment body, starts pipeline fan 11, and the air after will thoroughly disinfecting is discharged by air-out pipeline 9, and grid 10 increases and blocks pipeline fan 11's outside, and the security is stronger, and this equipment has effectively improved the ventilation effect that disinfects.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
