Technical Field

The invention relates to the technical field of sterilization and disinfection, in particular to equipment capable of disinfecting a breathing machine and a mask hose, and more particularly relates to an ozone disinfection device and an ozone disinfection system for actively removing ozone.

Background

At present, the mode of disinfecting medical instruments, tableware, food processing and the like is ozone disinfection. Ozone disinfection has many advantages, such as good sterilization effect, thoroughness of space dead angle diffusion, low cost, environmental protection, little harm to human body inhalation, and the like.

However, ozone disinfection is not perfect and has its own drawbacks. Because many disinfection products on the market utilize ozone to sterilize and disinfect objects to be disinfected in a closed space, and the disinfection effect can be achieved only when certain ozone concentration is achieved. The attenuation of the residual ozone needs a certain time after the disinfection, and after the disinfection process is finished, a large amount of residual ozone still exists in the closed space, and if measures are not taken, the residual ozone is completely recovered and removed. This can cause the items to be disinfected to often be associated with a harsh and unpleasant smell, and a large inhalation can also be a health hazard.

The mainstream solution to this problem in the market is to place consumables such as activated carbon inside the disinfection device, but the activated carbon needs to be replaced regularly, which increases the cost for the user and is inconvenient to use. In addition, when the sterilizing apparatus is used to sterilize the inside of a device to be sterilized (e.g., a ventilator, etc.), the activated carbon cannot remove odor from ozone remaining in a pipe connecting the device to be sterilized and the inside of the device to be sterilized. Secondly, the time and effect of the odor removal of the activated carbon are not ideal, and the activated carbon occupies the limited use space inside the disinfection equipment.

It is clearly seen that the ozone generator 13, the suction pump 14 and the filter 15 are installed in the interlayer between the outer casing 102 and the inner casing 101. In the working process of the ozone disinfection device 100, the control module 12 sends an instruction to start the ozone generator 13, ozone generated by the ozone generator 13 reaches the gas distribution unit 16 first, then is distributed by the gas distribution unit 16, a part of ozone enters the disinfection sealed cabin 11, and the other part of ozone enters the inside of the respirator along the hose to be disinfected (the shadow in the respirator is water, and if water exists in the water tank of the respirator, the ozone cannot permeate the bottom of the water tank). After the disinfection is finished, the ozone generator 13 stops working, the control module 12 sends an instruction to the air pump 14, the air pump 14 starts working to generate strong negative pressure, ozone in the disinfection sealed cabin 11 and the breathing machine is pumped back along the original path of the gas distribution unit 16, all the ozone is pumped back to the filter 15, the ozone is rapidly decomposed by the ozone oxidant filled in the filter 15, and therefore no ozone exists in the gas exhausted by the air pump 14.

As can be seen from the above, the ozone sterilization device 100 is in operation when performing ozone sterilization on the object 200 to be sterilized and the device 300 to be sterilized (see fig. 5, the solid line segment in fig. 5 represents a circuit control line, the solid line arrow represents an ozone output sterilization route, and the dotted line segment represents an ozone withdrawal filtration route):

on the one hand, ozone generated by the ozone generator 13 is diverted into the sterilization capsule 11 through the gas distribution unit 16 to perform sterilization treatment on the article to be sterilized 200 placed in the sterilization capsule 11; after the disinfection is finished, the air pump 14 is started, residual ozone in the disinfection sealed cabin 11 and the first pipeline 171 and the third pipeline 173 can be pumped out and enters the filter 15, particles in the filter 15 catalyze and decompose the ozone, pollution-free oxygen is formed after the ozone is decomposed, and finally the oxygen is discharged out of the disinfection sealed cabin 11 through an exhaust port of the air pump 14, so that the peculiar smell in the ozone disinfection device 100 is eliminated;

on the other hand, the ozone generated by the ozone generator 13 can also be distributed to the inside of the device to be sterilized 300 by the gas distribution unit 16, thereby performing a sterilization process on the device to be sterilized 300 (for example, medical equipment such as a respirator). Similarly, after the disinfection is completed, the air pump 14 is started, the ozone remained in the equipment 300 to be disinfected and the hose to be disinfected is discharged into the filter 15, the particles in the filter 15 catalyze and decompose the ozone, the ozone is decomposed to form pollution-free oxygen, and finally the ozone is discharged out of the equipment 300 to be disinfected through the exhaust port of the air pump 14, so that the peculiar smell in the equipment 300 to be disinfected is eliminated. More importantly, the ozone residue in the sterilizing sealed cabin 11 and the first and third pipelines 171 and 173, and the ozone residue in the device 300 to be sterilized and the hose to be sterilized are all exhausted after being catalyzed and decomposed by the filter 15, so that the ozone pollution to the external environment is avoided.

In conclusion, the ozone disinfection device 100 can be used for rapidly disinfecting the object 200 to be disinfected and the equipment 300 to be disinfected by ozone, and can actively recover, decompose and disinfect the ozone generated in the disinfection process, thereby ensuring the personal safety and environmental sanitation safety of users.

In some other embodiments, the filter 15 may be designed to be connected to the exhaust port of the suction pump 14. Here, after the air pump 14 is started, the residual ozone in the sterilization chamber 11 and the first and third pipes 171 and 173 flows through the air pump 14 and then flows into the filter 15, and the filter 15 performs the ozone elimination treatment and then is evacuated.

Further, the ozone disinfection device 100 further comprises a sealing plug 166; the sealing plug 166 is used for sealing off the fourth port 164. In this way, when we only need to sterilize the article 200 to be sterilized placed in the sterilization chamber 11, the sealing plug 166 can be used to block the fourth port 164 to prevent the ozone generated during the operation from escaping from the fourth port 164 (see fig. 6).

It will be understood by those skilled in the art that in order to rapidly inject the ozone generated by the ozone generator 13 into the disinfection capsule 11 and the interior of the apparatus 300 to be disinfected during the disinfection process, an electromagnetic pump or a blower fan may be provided for the ozone generator 13, thereby increasing the working efficiency.

The peripheral ledge separates the first cavity from the second cavity. The first cavity and the outer circumferential wall form the third interface 163; the inner circumferential wall and the central barrier form the fourth interface 164. The second port 162 is cylindrical and connected to a portion of the outer circumferential wall surrounding the first cavity, and the second port 162 is directly communicated with the first cavity. The first port 161 is cylindrical and is connected to a portion of the outer circumferential wall surrounding the first cavity, and the first port 161 is directly communicated with the first cavity. As can be seen from the above, the structural design of the gas distribution unit 16 fully considers the factors of smoothness of the gas flow and the gas pressure, etc., so as to optimize the exhaust effect and facilitate the smooth exhaust of the residual ozone. Further, referring to fig. 3 or fig. 4, the second port 162 and the first port 161 are located on the same side and are arranged in parallel, so as to facilitate connection of internal pipelines.

In this way, it is achieved that the ozone sterilizing apparatus 100 operates only when the upper cover 103 is closed; when the upper cover 103 is opened, the ozone sterilizing apparatus 100 is automatically stopped. Thereby, the upper cover 103 is prevented from being accidentally opened to cause the continuous leakage of ozone.
