Ozone sterilization device

The present invention relates to a sterilization device, and more particularly to an ozone sterilization device.

Bacteria are difficult to see with the naked eye, but they have a major impact on people's lives. When people are less resistant, if they suffer from bacterial infections, they will easily cause multiple illnesses, which will affect the time of recovery, and may cause life-threatening risks. In order to achieve the effect of sterilization, it is generally sterilized by means of high temperature and high pressure, but the high temperature and high pressure method is only suitable for use in high temperature and high pressure resistant equipment articles, and the preservation of articles is limited. In addition, there is also a method of sterilizing by using ethylene oxide, which is to sterilize the object to be sterilized in an environment of ethylene oxide, and since the ethylene oxide causes harm to the human body, after the sterilization is completed, Long-term aeration must be carried out to prevent ethylene oxide from remaining on the surface of the article. Generally, if the residual ethylene oxide on the surface is below 10 ppm, it meets the standards for use and safety, but consumers still There will be some doubts. The gamma ray is also used for disinfection on the market, but the ray can only be used to sterilize the irradiated parts. If there is a dead angle, the complete disinfection effect cannot be achieved, and the disinfection and sterilization effect is rather limited.

In addition, bacteria are also present in foods, especially fresh foods, which usually have to undergo strict control, not only through a strict sterilization process, but also must be strictly controlled during transportation to avoid bacterial Reproduction.

Most importantly, regardless of any of the above sterilization methods, there are different degrees of problems. If any of the small problems occur, it may become invalid sterilization, and the effect of sterilization is greatly reduced.

The main purpose of the present invention is to provide a safe and effective sterilization device and to ensure that the articles after sterilization and sterilization are free from residual gas and sterilization dead spots.

The sterilization housing has a confined space for accommodating a preservative, and the preservative is coated in a medical grade dialysis container; the temperature management unit controls the temperature of the confined space, and enters the sterilization housing in the ozone gas The temperature is reduced to less than six degrees Celsius; the pressure management unit adjusts the pressure of the closed space.

It can be seen from the above description that the novel has the following characteristics:

First, the use of the ozone gas activity characteristics to achieve the sterilization effect, to avoid the use of other sterilization gases such as ethylene oxide must undergo a long period of aeration process, in order to avoid the problem of toxic gas residue.

Second, in conjunction with the use of the medical grade dialysis container, ozone can enter the medical grade dialysis container to sterilize the deposit, and after sterilization, block the re-invasion of bacteria, effectively maintaining the sterile environment of the preserve.

Third, do not need high temperature sterilization, but can meet most of the preservation requirements, especially the sterilization and preservation of advanced products.
