The invention discloses a device and method capable of inhibiting
aerosol propagation and disinfecting and a
toilet bowl, the device is used for the
toilet bowl, can spray a
water curtain capable of covering the inner wall surface of the
toilet bowl and disinfect the inner wall surface of the toilet bowl, and comprises a
disinfectant storage container, an
infusion pump, a
water curtain nozzle, a switching mechanism, a control valve and a water conveying
pipe, the water inlet end of the water conveying
pipe is connected with the control valve so as to control whether water enters the water conveying
pipe or not, the water outlet end of the water conveying pipe and the
disinfectant storage container are connected with an inlet of the
infusion pump through the switching mechanism, and the switching mechanism controls the water conveying pipe and the
disinfectant storage container to be alternately communicated with the inlet of the
infusion pump; and an outlet of the infusion pump is communicated with the
water curtain nozzle. After a user uses the toilet bowl, the water curtain can cover the inner wall face of the toilet bowl, so that
aerosol generated by flushing of the toilet bowl is inhibited from spreading outwards, meanwhile, the inner wall face of the toilet bowl is disinfected after flushing of the toilet bowl is completed, and pathogenic viruses on excrement left on the inner wall face of the toilet bowl are avoided.
