Air sterilization device

Abstract

The invention provides an air sterilization device which comprises a gas injection unit, a pressure reduction unit, a pressurization container assembly and a plurality of sterilization assemblies, the pressurization container assembly comprises an air cylinder and a piston, the piston is configured to move relative to the air cylinder, and the piston and the air cylinder jointly form an inner cavity with variable volume; the sterilization assembly is arranged in the inner cavity and is provided with a sterilization light source facing the interior of the inner cavity so as to sterilize the gas in the air cylinder; the air cylinder is provided with an air inlet capable of being opened and closed and an air outlet capable of being opened and closed, and the air inlet and the air outlet are both communicated with the inner cavity. The gas injection unit is connected to the gas inlet and is configured to feed gas to be sterilized into the cylinder; the pressure reduction unit is connected to the gas outlet and is configured to reduce the pressure of the gas flowing out of the gas outlet. The sterilization device is simple in structure and good in sterilization effect.

Description

technical field [0001] The invention relates to the technical field of ultraviolet sterilization, in particular to an air sterilization device. Background technique [0002] In recent years, the popularization of air-conditioning has increased the probability of people often being in various confined spaces, and the urban building syndrome, indoor air-conditioning disease, organic pollution, etc. caused by people's modern living environment and indoor decoration have greatly increased the possibility of respiratory tract infection. Sexuality directly affects people's health and life safety, therefore, it has also attracted people's attention to air disinfection. The air sterilization device is particularly important, mainly a machine that disinfects and sterilizes the air through the principles of filtration, purification, and sterilization. [0003] At present, the existing air sterilization device includes a housing and air inlets and air outlets respectively arranged on ...

AI Technical Summary

Problems solved by technology

[0004] However, the air sterilizing device in the prior art, due to the fast air flow rate, adopts the direct air sterilizing method and the indirect sterilizing method. Insufficient time and irradiation dose, so that the bacteria in the air cannot be effectively inactivated, and the sterilization effect is poor; on the other hand, the overall structure design is complex, inconvenient for users to use, and there will be problems such as increased power consumption
