The invention relates to the technical field of ventilation and purification, and discloses an improved negative pressure isolation ward ventilation and purification device. The improved negative pressure isolation ward ventilation and purification device comprises a total heat exchange unit, a connecting block is fixedly mounted on the left side of the total heat exchange unit, a rubber block is movably clamped to the bottom of the connecting block, and a clamping spring is fixedly connected to the bottom of the rubber block. The bottom of the clamping spring is fixedly connected with a limiting plate, and the bottom of the limiting plate is fixedly connected with a fixing shaft. According to the improved negative pressure isolation ward ventilation and purification device, a rotary pull rod is extruded to drive a limiting plate to rotate and ascend, the rubber block is clamped into the inner surface of the connecting block under the action of the clamping spring, and meanwhile the limiting plate is clamped with a limiting groove formed in the inner surface of the connecting block; and then a clamping block is clamped with a semicircular opening formed in the outer surface of the connecting block, so that connection between a negative ion generator and the connecting block is completed, and the effects of improving the concentration of indoor negative oxygen ions and ensuring the indoor air quality are achieved.
Description
technical field [0001] The invention relates to the technical field of ventilation and purification, in particular to an improved ventilation and purification device for a negative pressure isolation ward. Background technique [0002] With the advent of the epidemic, most of the existing buildings, including temporary isolation hotels, isolation wards, and home isolation residences, cannot effectively isolate the virus from the fresh air / exhaust system. The fresh air purification and exhaust system can effectively isolate viruses in the home environment, and can realize the comprehensive elimination of viruses in the entire fresh air system. Adding fullerene purification outlets makes the indoor negative oxygen ion concentration reach the concentration in the forest, which is beneficial to the human body. The rehabilitation function of health and chronic diseases, the control of indoor air pressure gradient, realize the one-way operation of fresh air from the clean area of ...
