Bed unit sterilizing machines using ozone as a sterilizing factor have been used in public places such as hospitals, hotels and the like for sterilizing porous fabrics such as quilts, pillows, mattresses and the like. Chinese granted utility model patent (patent number: 2006200350650) discloses a bed unit ozone sterilizer, which comprises a casing, an ozone generator, an air pump, an electric appliance control valve, a sterilizing container and an ozone reducer; the electric appliance control valve is divided into an exhaust electric appliance control valve and an air inlet electric appliance control valve; the air pump is connected with the ozone reducer and the exhaust electric appliance control valve through pipe fittings to form an exhaust loop, the air pump is connected with the ozone generator and the air inlet electric appliance control valve through pipe fittings to form an air inlet loop, and the exhaust loop and the air inlet loop are both connected with a disinfection container (disinfection bag). The whole process of ozone disinfection can be completed by manual operation and can be automatically completed according to a set program. Because the ozone reducer is arranged on the exhaust loop, after the disinfection of the disinfected objects is finished, the ozone in the disinfection container (disinfection bag) is reduced into oxygen and then exhausted out of the machine, thereby being beneficial to environmental protection and human health.

The disinfection procedure of the bed unit disinfection machine comprises four links of air pumping, ozone charging, disinfection maintaining and ozone resolving, wherein in the first link, air pumping is to put disinfection objects into a disinfection bed bag for sealing, and an air pump works to discharge air in the disinfection bed bag through an exhaust loop so as to ensure the concentration of ozone in the disinfection sealing bag and facilitate the ozone to permeate the inside of the fabric for disinfection easily; the second step is the process that the ozone filling air pump fills high-concentration ozone generated by the ionization of the air through the ozone generator into the disinfection sealing bed bag through the air filling loop; the third step of 'disinfection and maintenance', namely the ozone filled in the previous step is sealed in a disinfection bed bag for a certain time, so that the sterilization effect of the ozone is exerted; in the fourth step, the ozone in the disinfection bed bag is catalytically reduced into air through the ozone decomposition catalyst and discharged through the exhaust loop by the ozone analysis air pump, so that the process harmless to people and environment is realized.

The bed unit sterilizer can sterilize articles in the sterilization bag by using ozone, and the ozone in the sterilization bag is reduced into air to be discharged after sterilization is completed, so that the sterilization and harmless process is realized. However, the diameters of the air charging loop pipeline and the air discharging loop pipeline of the bed unit disinfection machine are the same, namely the flow rates of air charging and air discharging are the same, so that the working time of two links of air pumping and ozone analysis in the disinfection process is too long, and the time of the whole disinfection process is too long. The sterilization time is too long, the utilization rate of the machine is reduced, the working efficiency of operators is also reduced, and the product is not beneficial to popularization and use.

The bed unit sterilizer adopts a standing and sealing mode for gas in the sterilization bag in the 'sterilization keeping' link, ozone in the sterilization bag cannot be supplemented, the ozone is greatly attenuated in the sterilization process, the sterilization efficiency of the 'sterilization keeping' link is reduced by the mode, and the sterilization time is prolonged.
