Abstract

A gas sterilization apparatus comprises a housing with a sterilizing unit and a power device. An ozone generator and an air purifying device are provided in the housing. The power device is operated to allow air to pass through the ozone generator and flow into the sterilizing unit so as to perform sterilization. After being sterilized, the air in the sterilizing unit can be drained via the purification of the air purifying device. The gas sterilization apparatus can sterilize the air by use of ozone, thus it is applicable for articles and materials which can be sufficiently soaked by ozone to achieve the sterilization effect, and it can reduce the denaturation of biological materials, so it has wide application. The gas sterilization apparatus can sterilize the articles and materials in simple and convenient ways for user, so it is beneficial to use in the industry.

First claim

What is claimed is:

1. A gas sterilization apparatus comprising:
a housing having an assembling chamber, a dust accumulating unit, and a sterilizing unit mounted in the housing, the dust accumulating unit disposed close to the sterilizing unit, the dust accumulating unit having a first dust accumulating chamber and a second dust accumulating chamber, the first dust accumulating chamber communicating with the second dust accumulating chamber with a filter mounted between the first dust accumulating chamber and the second dust accumulating chamber, and the second dust accumulating chamber communicating with the sterilizing unit with another filter mounted between the second dust accumulating chamber and the sterilizing unit;
a power device including a driving assembly and a control switch, the driving assembly including a first pump and a second pump, an inlet end of the second pump connected to and communicating with the sterilizing unit via pipes, and the control switch electrically connected to the driving assembly;
an ozone generator mounted in the assembling chamber, and connected to and communicating with an outlet end of the first pump and the first dust accumulating chamber of the dust accumulating unit via pipes; and
an air purifying device mounted in the assembling chamber and including an antibacterial ceramic and a filter assembly, the antibacterial ceramic having an inlet and an outlet, the outlet connected to and communicating with an inlet end of the first pump and the sterilizing unit, and the filter assembly connected to and communicating with an outlet end of the second pump via pipes to exhaust sterilized gas.

2. The gas sterilization apparatus as claimed in claim 1 , wherein the first dust accumulating chamber is disposed below the second dust accumulating chamber, and the dust accumulating unit is disposed between the assembling chamber and the sterilizing unit.

3. The gas sterilization apparatus as claimed in claim 1 , wherein the first dust accumulating chamber and the second dust accumulating chamber are disposed next to each other, the dust accumulating unit is disposed below the sterilizing unit, and the assembling chamber is disposed at the same side as the dust accumulating unit and the sterilizing unit.

4. The gas sterilization apparatus as claimed in claim 1 , wherein the filter assembly includes a first activated carbon filtration core and a second activated carbon filtration core, the first activated carbon filtration core is connected to and communicates with the outlet end of the second pump and the second activated carbon filtration core via pipes, and an exhaust pipe is connected to the second activated carbon filtration core to exhaust gas.

5. The gas sterilization apparatus as claimed in claim 2 , wherein the filter assembly includes a first activated carbon filtration core and a second activated carbon filtration core, the first activated carbon filtration core is connected to and communicates with the outlet end of the second pump and the second activated carbon filtration core via pipes, and an exhaust pipe is connected to the second activated carbon filtration core to exhaust gas.

6. The gas sterilization apparatus as claimed in claim 3 , wherein the filter assembly includes a first activated carbon filtration core and a second activated carbon filtration core, the first activated carbon filtration core is connected to and communicates with the outlet end of the second pump and the second activated carbon filtration core via pipes, and an exhaust pipe is connected to the second activated carbon filtration core to exhaust gas.
