Hydrogen peroxide sterilization device for space sterilization and equipment sterilization and control method thereof

Abstract

The invention relates to a hydrogen peroxide sterilization device for space sterilization and equipment sterilization and a control method thereof. The hydrogen peroxide sterilization device comprises a shell, a dehumidification heating module, a fan assembly, a valve and a peristaltic pump; the dehumidification heating module comprises a shell, and a heating block is arranged in the shell; the valve is provided with a plurality of ports; the shell is provided with an inlet and an outlet; the inlet is communicated with the air outlet of the fan assembly; the outlet is communicated with a first port of the valve; the peristaltic pump is respectively communicated with a hydrogen peroxide storage device and the dehumidification heating module through pipelines; the shell is provided with at least one outlet quick coupler and at least one inlet quick coupler; the outlet quick coupler and the inlet quick coupler are respectively communicated with a second port of the valve and an air inlet of the fan assembly; at least one diffusion nozzle is arranged on the shell; and the diffusion nozzle is communicated with a third port of the valve. According to the invention, the sterilization modes can be switched, and the requirements of space sterilization and equipment sterilization are met.

Description

technical field [0001] The present invention relates to a sterilization equipment and its control method, especially a hydrogen peroxide sterilization device and its control method, specifically a hydrogen peroxide space sterilization and equipment sterilization device and its control method. Background technique [0002] At present, most of the existing vaporized hydrogen peroxide sterilization equipment has a single function, or only have two quick-fit joints, which can only be used for sterilization in the equipment cavity; or only have a diffusion nozzle, which can only be used for Space sterilization. If the user needs both space sterilization and sterilization in the equipment cavity, it is necessary to purchase two types of equipment, or to equip an additional expensive diffusion nozzle accessory, which not only greatly increases the purchase cost, but also makes the operation complicated , affecting efficiency. Moreover, the existing hydrogen peroxide sterilization...

Problems solved by technology

[0002] At present, most of the existing vaporized hydrogen peroxide sterilization equipment has a single function, or only have two quick-fit joints, which can only be used for sterilization in the equipment cavity; or only have a diffusion nozzle, which can only be used for Space sterilization

If the user needs both space sterilization and sterilization in the equipment cavity, it is necessary to purchase two types of equipment, or to equip an additional expensive diffusion nozzle accessory, which not only greatly increases the purchase cost, but also makes the operation complicated , affecting the use efficiency

Moreover, the existing hydrogen peroxide sterilization equipment uses a fixed supply rate of hydrogen peroxide solution, resulting in a low concentration in the early stage, which is not conducive to improving the sterilization effect and efficiency
