Mobile sterilization station

Abstract

The invention relates to the technical field of air sterilization and disinfection equipment, in particular to a mobile sterilization station. The mobile sterilization station comprises a machine casing, the machine casing is provided with an air inlet, the air inlet is provided with a first air suction fan, the air inlet is sequentially provided with a pre-filter, a cold catalytic agent filter module, an HEPA filter screen, a fan unit, an air duct and a circulation duct, the air duct is provided with a photocatalyst filter assembly, a first branch channel is provided with an air outlet, the air outlet is provided with a second air suction fan and a first valve, a second branch channel is provided with a second valve and an air quality detection module, and the circulation duct is providedwith a third air suction fan and an ultraviolet light unit. The mobile sterilization station has the beneficial effects that four-stage filtration is achieved; multiple four-stage filtration is achieved until the air quality detection module detects that the air quality index is lower than the standard value, then the first valve is opened for exhausting, and therefore the efficiency of discharging qualified gas is improved; and air passing through the circulation duct is further sterilized by the ultraviolet light unit, and therefore the sterilization rate is improved.

Description

technical field [0001] The invention relates to the technical field of air sterilization and disinfection equipment, in particular to a mobile sterilization station. Background technique [0002] As a special place, the hospital receives a large number of patients every day, and the patients will carry a large number of bacteria. If there are not enough disinfection measures, the interior of the hospital will become a warehouse for bacteria. According to the domestic survey results for several years, the total excess rate of hospital air bacteria is 42.8%-55%, and nosocomial infection is prone to occur in such a hospital environment. Nosocomial infection refers to the infection acquired by inpatients in the hospital, including the infection during hospitalization and the infection after discharge from the hospital. Among them, respiratory infectious diseases accounted for 36.19% to 70.89% of nosocomial infections. Therefore, it is urgent to effectively control the secondar...

Problems solved by technology

[0004] 1. When there are people and the hospital and outdoor ventilation, the air in the medical environment will be mixed with large particles of dust, odorous gas, germs and bacteria, and the composition of the air that needs to be sterilized and filtered is complex;

[0005] 2. The current air disinfection technology is difficult to meet the common requirements of preventive disinfection and terminal disinfection. Preventive disinfection only needs to control the air microorganisms to a certain standard; while terminal disinfection must thoroughly disinfect the contaminated environment of patients

[0008] For example, the electrostatic air purifier with Chinese Patent No. 93226519.7, the sterilizing air purifier with Chinese Patent No. 97234337.7, and the combined electrostatic field device with Chinese Patent No. 97106376.1. The sterilization equipment has the following disadvantages: in the actual operation process, it will produce ozone and other substances that damage the environment and its use is restricted

[0009] The Chinese patent number is: 201520968447.8 mobile sterilizing station, the above-mentioned mobile sterilizing station adopts ultraviolet light to sterilize. In actual operation, the existing equipment causes some ultraviolet radiation to the outside due to the position of the ultraviolet light, which will affect the human body for a long time. Cause certain damage, and the actual sterilization effect of the current ultraviolet sterilization equipment is not ideal; and it only sterilizes the air once, and the sterilization effect cannot be guaranteed

[0010] For the medical environment with more stringent requirements on bacterial contamination, the traditional mobile sterilization station cannot meet or quickly meet the sterilization and disinfection requirements of the environment, and the scope of use of the traditional mobile sterilization station is limited

[0011] Therefore, the sterilization effect of the existing mobile sterilization station and other sterilization equipment is actually not ideal. At present, there is an urgent need for a sterilization equipment with higher sterilization efficiency and better sterilization effect.
