A silent air purification device without consumables for wards

Abstract

The invention discloses a mute consumable-free air purifying device for a ward. The mute consumable-free air purifying device comprises an air purifying part, a connecting pipe and an air outlet part,and the air purifying part is located outside a wall of the ward and is provided with a pipe body and an air inlet part. A cavity is formed in the pipe body, and the air inlet part is connected withone end of the pipe body and communicates with the cavity in the pipe body. The air inlet part is provided with an air inlet hole and a mute fan. A caliber-adjustable valve body is arranged at the other end of the pipe body and is opposite to the air inlet part, and a first exhaust opening is formed in the center of the valve body and allows airflow in a clean airflow area to be exhausted. A second exhaust opening is formed in the periphery of the valve body and allows airflow in a dirty airflow area to be exhausted. According to the mute consumable-free air purifying device, the caliber of the valve body can be adjusted by operating connecting handles to move the position of an adjusting ring to keep the cleanliness of the clean airflow introduced into the first exhaust opening basicallyunchanged. The second exhaust opening is formed in the periphery of the valve body, the airflow in the dirty airflow area is exhausted, and the consumable replacement cost and cleaning and maintenancecost are omitted for a user.

Description

technical field [0001] The invention relates to an air purification device, in particular to a silent air purification device without consumables for wards. Background technique [0002] With the development of global industrialization and increasing population, ambient air pollution is increasing. Dust, bacteria, peculiar smell and harmful gas in the air have a direct impact on human health, especially the indoor air quality is increasingly concerned by people. The quality of the air in the hospital ward directly affects the health of patients and accompanying staff. Wards are densely populated, and indoor breeding and residual viruses and bacteria are likely to cause secondary pollution and infection. It is of great significance to prevent and control the quality of indoor air in wards. At present, most of the air purification devices used in wards adopt the method of physical filtration for air purification. However, this type of product has disadvantages: physical fil...

AI Technical Summary

Problems solved by technology

However, this type of product has disadvantages: physical filtration air purification uses filter elements to absorb particulate matter and germs in the air, and expensive filter elements are consumables that need to be replaced regularly, otherwise it will increase the risk of users being harmed by virus bodies and ultrafine mixtures

Almost all filter elements are made of filter mesh or dust bag or porous material, because the surface of the filter element must be perpendicular to the direction of air flow (or nearly vertical) in order to collect and filter out suspended particles. During operation, The surface of the filter element will accumulate more and more suspended particles such as dust, pollen, fungus, bacteria, etc., so the consumables will generate greater and greater resistance to the flow of air. In order to keep the wind force at the air outlet constant, speed up The speed of the fan pressurizes the air so that it can pass through the consumables more quickly, and the noise generated during operation will gradually increase, which will have a negative impact on the rest of the patient in the ward and is not conducive to the recovery of the patient
