[0001] The utility model belongs to the technical field of household appliances, and particularly relates to a portable ozone disinfection machine. Background Art

[0002] Most of the existing ozone sterilization devices on the market inject ozone into a cavity under normal pressure and then disinfect the items inside. When injecting ozone into the cavity, since the cavity is in a normal pressure state, the ozone concentration and injection volume in the cavity will be affected when establishing a disinfection environment by injecting ozone. And the disinfection of objects is affected by the injected ozone concentration. Therefore, the existing method of injecting ozone to establish a disinfection environment cannot completely and quickly disinfect viruses or bacteria, thus affecting the disinfection efficiency.

[0003] Therefore, how to provide a portable ozone disinfection machine that is convenient to carry, highly efficient and thorough in disinfection is an urgent problem for those skilled in the art. Summary of the Utility Model

[0050] Specific usage process:

[0051] In the early stage, the items to be disinfected need to be put into the disinfection bag, the sealing zipper is fastened, and the airtight connection between the air passage conversion chamber structure and the disinfection bag is checked. After checking, press the confirmation button, and the air pump enters the air extraction mode. The indicator light starts to flash, indicating that it has entered the working state, indicating air extraction, and the disinfection bag is subjected to air extraction treatment. The program-controlled display starts timing. When the pressure sensor assembly connected to the air passage conversion chamber detects that the air passage conversion chamber and the disinfection bag are in a negative pressure state, the timing of the program-controlled display returns to zero, and the air pump air extraction mode is converted to the air pump air injection mode, and the ozone generator is turned on. The memory of the working time of the air pump air extraction mode starts to control the countdown of the ozone air injection time, which is equal to the air extraction time, and the disinfection status is displayed. The disinfection bag in a negative pressure state has received a high concentration injection of ozone, creating a strong disinfection condition inside the disinfection bag. After the disinfection is completed and the ozone is reduced, the machine emits a beeping sound to indicate that the disinfection bag can be safely opened and the disinfected items can be taken out.

[0052] This product uses the air pump set inside the machine to adjust the air extraction mode, extract the air in the space environment of the items to be disinfected in the disinfection bag to a negative pressure. Under the perception of the pressure sensor assembly, the air pump air extraction mode is turned off, and at the same time, the air pump air injection mode is adjusted. The change between the air injection mode and the air extraction mode is actually realized through different pipelines, and the ozone generator is turned on. In the air injection mode, the ozone generated by the ozone generator in the air passage conversion chamber enters the disinfection bag. The ozone injection time is equal to the cut-off time of the air extraction mode, creating a disinfection environment for the items to be disinfected in the disinfection bag. The high-concentration ozone environment can quickly and thoroughly disinfect the items comprehensively.
