Abstract

A disinfection application, particularly, to a device capable of disinfecting a ventilator as well as a face mask and a hose, and more particularly, to an ozone disinfection device, an ozone disinfection system, and an ozone disinfection method. The ozone disinfection device includes: a sealed disinfection space, a gas distribution unit, an ozone generation unit, a suction pump, a filter, and a control module.

Claims (57)

1 . An ozone disinfection device, comprising:

a disinfection space configured to receive a device to be disinfected or temporarily store ozone;

wherein the disinfection space is configured to be openable;

at least one interface configured to communicate with the device to be disinfected;

a suction pump having a suction port and an exhaust port;

wherein a suction volume of the suction pump is not lower than an exhaust volume of an ozone generation unit;

a filter configured to absorb the ozone and/or catalyze a decomposition of the ozone, wherein the filter further includes at least one gas inlet and at least one exhaust hole, wherein the filter is in communication with the suction pump; and

a control module configured to connect the ozone generation unit to the suction pump and control an operation of the ozone generation unit and the suction pump,

wherein the control module is configured to control the ozone generation unit to output the ozone so that a concentration of the ozone in the disinfection space is not lower than a concentration value to kill germs, and

wherein the control module activates the suction pump, and wherein the suction pump generates a negative pressure to pump any remaining ozone inside the disinfection space and the device to be disinfected to the at least one gas inlet of the filter.

2 . The ozone disinfection device according to claim 1 , wherein the disinfection space is sealed.

3 . The ozone disinfection device according to claim 1 , wherein the ozone disinfection device further comprises a gas distribution unit that includes the at least one interface.

4 . The ozone disinfection device according to claim 3 , wherein the ozone disinfection device further comprises an ozone generator configured to generate the ozone and a power apparatus configured to deliver the ozone to the gas distribution unit.

5 . The ozone disinfection device according to claim 4 , wherein the power apparatus is a positive pressure gas pump.

6 . An ozone disinfection device, comprising:

a disinfection space configured to receive a device to be disinfected or temporarily store ozone;

at least one interface configured to communicate with the device to be disinfected;

a suction pump having a suction volume not lower than an exhaust volume of an ozone generation unit, wherein the suction pump includes a suction port and an exhaust port;

a filter configured to absorb the ozone and/or catalyze a decomposition of the ozone, wherein the filter further includes at least one gas inlet and at least one exhaust hole, wherein the filter is in communication with the suction pump; and

a control module configured to connect to the suction pump and control an operation of the suction pump,

wherein the filter includes at least one filter layer,

wherein the at least one filter layer is provided between the at least one gas inlet and the at least one exhaust hole, and wherein the at least one filter layer is configured to communicate with the at least one gas inlet of the filter,

wherein the control module activates the suction pump, and wherein the suction pump generates a negative pressure to pump any remaining ozone inside the disinfection space and the device to be disinfected to the at least one gas inlet of the filter.

7 . The ozone disinfection device according to claim 6 , wherein the disinfection space includes an outer box and an inner box, and wherein the outer box includes a top cover, a base, and a peripheral side wall configured to connect the top cover and the base.

8 . The ozone disinfection device according to claim 6 , wherein the suction pump and the filter are both provided between the inner box and the base.

9 . The ozone disinfection device according to claim 6 , wherein the control module includes a display screen that shows work progress and work content, and wherein the work progress includes a percentage of a total work time or a countdown of the total work time.

10 . An ozone disinfection device, comprising:

an inner box;

an outer box;

a disinfection space provided in the inner box, the disinfection space configured to receive a device to be disinfected or temporarily store ozone;

wherein the disinfection space is configured to be openable;

an ozone generation unit and at least one ozone outlet, wherein the ozone outlet is configured to communicate with the disinfection space, and wherein the ozone generation unit includes an ozone generator configured to generate the ozone and a power apparatus configured to deliver the ozone to the disinfection space;

a suction pump having a suction port and an exhaust port;

wherein a suction volume of the suction pump is not lower than an exhaust volume of the ozone generation unit;

a filter configured to absorb the ozone and/or catalyze a decomposition of the ozone, wherein the filter is located between the inner box and a base of the outer box when the inner box is inserted into the outer box, wherein the filter further includes at least one gas inlet and at least one exhaust hole, wherein the filter is in communication with the suction pump; and

a control module configured to connect the ozone generation unit to the suction pump and control an operation of the ozone generation unit and the suction pump,

wherein the control module activates the ozone generation unit, and the ozone generated by the ozone generation unit flows into the device to be disinfected and the disinfection space,

wherein the control module activates the suction pump, and wherein the suction pump generates a negative pressure to pump any remaining ozone inside the disinfection space and the device to be disinfected to the at least one gas inlet of the filter; and

wherein the ozone disinfection device further comprises a gas distribution unit that has at least one interface.

11 . The ozone disinfection device according to claim 10 , wherein the disinfection space is opened and closed in a drawer type manner.

12 . The ozone disinfection device according to claim 10 , wherein the disinfection space is opened and closed in a flip type manner.

13 . The ozone disinfection device according to claim 10 , wherein the ozone generation unit is connectable to the at least one interface of the gas distribution unit via a pipeline.

14 . The ozone disinfection device according to claim 10 , wherein the gas distribution unit is a three-way pipe.

15 . An ozone disinfection device, comprising:

an inner box;

an outer box;

a disinfection space provided in the inner box, the disinfection space configured to receive a device to be disinfected or temporarily store ozone;

wherein the disinfection space is configured to be openable;

at least one interface configured to communicate with a device to be disinfected;

a filter configured to absorb the ozone or catalyze a decomposition of the ozone, wherein the filter is located between the inner box and a base of the outer box, wherein the filter further includes at least one gas inlet and at least one exhaust hole, wherein the filter is in communication with a suction pump;

wherein the filter includes at least one filter layer; and

a control module configured to connect an ozone generation unit to the suction pump and control an operation of the ozone generation unit and the suction pump,

wherein the control module controls the ozone generation unit to stop working and activates the suction pump, and wherein the suction pump generates a negative pressure to pump any remaining ozone inside the disinfection space and the device to be disinfected to the at least one gas inlet of the filter.
