In order to solve the above problems, referring to fig. 1, the present invention provides a sterilizing apparatus including: a liquid storage container 1, a first disinfection pipeline 2 and a second disinfection pipeline 3. The first disinfection pipeline 2 is connected with the liquid inlet 11 of the liquid storage container 1, a first water injector 21 is arranged on the first disinfection pipeline 2, and the first water injector 21 is used for mixing external disinfection gas with liquid flowing along with the first disinfection pipeline 2. The second disinfection pipeline 3 passes through the outer wall of the liquid storage container 1 and extends to the inner cavity of the liquid storage container 1, the second disinfection pipeline 3 is provided with a second water injector 31, and the second water injector 31 is used for mixing disinfection gas in the liquid storage container 1 with liquid flowing along with the second disinfection pipeline 3.
In detail, the water jet used in the invention can be of a common water jet type, for example, a negative pressure cavity is arranged in the water jet, and the water jet also comprises a liquid inlet, a liquid outlet and a gas inlet, wherein when pressure liquid sequentially flows through the liquid inlet, the negative pressure cavity and the liquid outlet, negative pressure is formed in the negative pressure cavity, and gas can enter the negative pressure cavity through the gas inlet and be mixed with the liquid to flow out through the liquid outlet together. The "first" and "second" in the first water jet 21 and the second water jet 31 are for convenience of distinguishing the setting positions of the two water jets, and the working principles thereof are identical.
The first water jet 21 of the present invention is disposed on the first sterilizing line 2, and the liquid sequentially passes through the liquid inlet and the liquid outlet of the first water jet 21, and the air inlet of the first water jet 21 may communicate with an external device for supplying sterilizing gas, such as an air tank, a gas pipe, etc. The second water jet 31 is arranged on the second disinfection pipeline 3, liquid sequentially passes through a liquid inlet and a liquid outlet of the second water jet 31, a gas inlet of the second water jet 31 is open, and disinfection gas can be supplied by the disinfection gas in the liquid storage container 1.
In operation, the first water jet 21 mixes the external sterilizing gas with the liquid in the first sterilizing line 2, and the mixed liquid continues to flow along the first sterilizing line 2 and enters the liquid storage container 1 through the liquid inlet 11. Since the sterilizing gas is not completely dissolved in the liquid, a small portion of the sterilizing gas is diffused to the top of the liquid storage container 1, the second water jet 31 is located in the liquid storage container 1, and the sterilizing gas diffused in the liquid storage container 1 can be mixed with the liquid in the second sterilizing line 3, and the mixed liquid continues to flow along the second sterilizing line 3 and is discharged into the liquid storage container 1.

The second disinfection line 3 enters the reservoir 1 from the top thereof, facilitating the placement of the second water jet 31 in the gas-collecting channel 13. The second water ejector 31 is used for mixing the disinfection gas sucked into the liquid in the second disinfection pipeline 3, and the mixed liquid continuously flows and is discharged to the bottom of the liquid storage container 1, so that only the reduction of the gas pressure is involved in the gas collecting hood 13, and the gas is facilitated to enter the gas collecting hood 13 under the action of negative pressure.
Referring to fig. 2, in one embodiment of the present invention, the drain port 32 of the second sterilizing line 3 is offset in height from the gas-collecting channel 13 and the air-guiding channel 12. As can be seen from fig. 2, the gas-collecting hood 13 and the air-guiding hood 12 are located on the same side of the liquid-storing container 1, the second sterilizing line 3 extends from the gas-collecting hood 13 to the bottom of the other side of the liquid-storing container 1, and the liquid-discharging port 32 of the second sterilizing line 3 is directed upward. The main flow path of the sterilizing gas is arranged between the gas collecting hood 13 and the air guide hood 12, so that the liquid discharge port 32 is staggered with the gas collecting hood 13 and the air guide hood 12 in the height direction in order to prevent the flowing of the sterilizing gas from being disturbed, and the liquid discharged from the liquid discharge port 32 can avoid the moving path of the sterilizing gas flowing out of the air guide hood 12, thereby reducing the disturbance of the flowing of the sterilizing gas and ensuring that the sterilizing gas can stably enter the gas collecting hood 13.
