Background technique

Disinfection cabinet refers to a tool for sterilization, heat preservation and dehumidification of tableware, tableware, towels, clothing, beauty and hairdressing appliances, medical equipment and other items through ultraviolet rays, far infrared rays, high temperature, ozone, etc. The shape is generally a cabinet shape. Most of the cabinet body is made of stainless steel.

At present, hospitals will sterilize reusable medical instruments, but most of them are soaked and sterilized in disinfection pools or disinfection tanks. After sterilizing medical instruments, medical staff need to wear gloves to fish them out. To a certain extent, the medical equipment cannot be completely disinfected. The disinfectant can easily contaminate the hands of the medical staff, and the medical equipment after disinfection is relatively wet, which is not conducive to the use of the medical staff. The disadvantage is that the drug soaking will damage the medical equipment. Larger, longer drying time, incomplete wiping, incomplete disinfection, stronger odor.

Therefore, ultraviolet disinfection cabinets are also used in this technical field to sterilize medical instruments. Ultraviolet disinfection is the use of ultraviolet rays of appropriate wavelengths to destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in the cells of microorganisms, causing growth cell death and (or) regenerative cell death, to achieve sterilization and disinfection Effect. Ultraviolet disinfection technology is based on modern epidemiology, medicine and photodynamics. It uses specially designed high-efficiency, high-intensity and long-life UVC band ultraviolet light to sterilize various bacteria, viruses, parasites, algae and other pathogens. Kill directly.

Ultraviolet rays have a certain bactericidal effect, but excessive exposure to ultraviolet rays is harmful to the human body. When ultraviolet rays act strongly on the skin, photodermatitis can occur, and erythema, itching, blisters, edema, eye pain, tears, etc. can appear on the skin, and serious skin cancer can also be caused. Ultraviolet rays act on the central nervous system, causing headaches, dizziness, and elevated body temperature. Acting on the eyes, it can cause conjunctivitis and keratitis, known as photoophthalmia, and may also induce cataracts.

Therefore, as a disinfection cabinet that is in long-term contact with people, it should be designed with adjustable ultraviolet protection. It should work effectively when it is far away from the human body, and stop working when the human body is close.

The domestic application number is CN201420663523.X, a kind of intelligent induction medical disinfection lamp adopts the form of combining infrared sensor, single-chip microcomputer and alarm horn, and the use of ultraviolet light has been improved to a certain extent, but this type of disinfection lamp does not have It solves the harm of ultraviolet light to the human body very well. At the same time, the ultraviolet disinfection lamp has a small surface irradiation range, cannot disinfect in all directions, and the overall disinfection is not thorough enough. Thereby, need badly a kind of ultraviolet disinfection cabinet that intelligently regulates ultraviolet rays.
