An air purification ventilation device

Abstract

The invention relates to the technical field of medical gas purification, in particular to an air purification and ventilation device, which includes a purification cabinet, and an air interception and gas delivery component is arranged on the upper side of the interior of the purification cabinet. This kind of air purification and ventilation device can complete the automatic detection and replacement of the purification filter cotton by setting the purification component, without manual intervention and assistance, and will not cause the equipment to shut down, and the air intake is realized through the air interception of the single cylinder, so that the overall operation process is purified. The area will not be directly connected to the outside world, to avoid the possibility of backflow and the possibility of dispersion and overflow of the filter material on the surface of the purification filter cotton in the shutdown state. When the piston moves down beyond the intake nozzle, the lower part of the closed air cylinder is in a closed state. At this time, the piston Move down to compress the air until the piston touches the mushroom head to unlock the plate and the sealing plug, so that the compressed air can be injected into the purification box at a very high speed, so as to use the air compression to increase the gas flow rate and press the air on the surface of the purification filter cotton, which can effectively speed up Air flow and purification efficiency in the equipment.

Description

technical field [0001] The invention relates to the technical field of medical gas purification, in particular to an air purification ventilation device. Background technique [0002] Bacteria in the air generally exist in groups and are attached to dust. Generally speaking, the more dust in the air, the more opportunities for bacteria to contact and attach to dust, and the chance of transmission increases. With the development of industry, With the growth of the economy and the improvement of living standards, people's requirements for the quality of life are also getting higher and higher, and air pollution brings a lot of inconvenience to our daily life, especially in some places with high requirements for environmental quality, such as: surgery Room, delivery room, baby room, infectious disease ward, etc., all have high requirements for air quality. [0003] In view of dust and other pollution in the air, air purification equipment is generally required in operating roo...
