Description

Air purifier for hospital

Technical Field

The invention belongs to the technical field of indoor air purification, and particularly relates to a hospital air purifier.

Background

As a special public place, hospitals have large flow of people and many sick patients, and exhaled gas is often provided with pathogens and has strong infectivity. Except for gas exhaled by patients with diseases in hospital wards, some patients with serious diseases can not get off the bed, the patients often urinate and urinate indoors, the patients eat and live in the wards, air in the wards is turbid, the recovery of the patients is not facilitated, and meanwhile mutual infection among the patients is easily caused.

Along with the development of social economy, the living environment of people is worsened more and more, but the requirement on the ambient air quality is higher and more, especially in hospitals, the medicine smell, bacteria, germs and the like are much higher than those in normal conditions, and the existing air purifiers are various, but the air purifiers which can be used in hospitals are relatively few, and the effects of smell removal, disinfection and sterilization are not ideal.

Disclosure of Invention

The invention aims to provide a hospital air purifier which can purify indoor air of a hospital and reduce infection of indoor patients. The purpose of the invention is realized by the following technical scheme.

The plasma generator comprises a glass tube, an inner electrode assembly arranged on the inner side of the glass tube and an outer electrode assembly arranged on the outer side of the glass tube, wherein the inner electrode assembly comprises an inner conductive metal net which is arranged in a tubular shape and is sleeved on the inner side of the glass tube, and the outer electrode assembly comprises an outer conductive metal net which is arranged in a tubular shape and is sleeved on the outer side of the glass tube and is matched with the inner conductive metal net to generate plasma air in a power-on state. The plasma generator raises the low voltage to positive high voltage and negative high voltage through the booster circuit, ionizes the air by utilizing the positive high voltage and the negative high voltage to generate a large amount of positive ions and negative ions, the quantity of the negative ions is larger than that of the positive ions, and the generated positive ions and the negative ions generate huge energy release at the moment of neutralizing positive and negative charges in the air, so that the structure of bacteria around the positive ions is changed or the energy is converted, the bacteria are killed, and the sterilization effect of the positive ions and the negative ions is realized. Because the quantity of the negative ions is greater than that of the positive ions, redundant negative ions still float in the air, and the effects of eliminating smoke and dust, eliminating peculiar smell and improving the quality of the air can be achieved, so that the health care effect of human health is promoted; the plasma generator simultaneously generates a large amount of negative ions and positive ions, and the quantity of the negative ions is far greater than that of the positive ions, so that the positive ions are immediately neutralized by the negative ions after being generated, so that a large amount of positive ions cannot exist in the air, and the positive ions and the negative ions are part of air components, so that a proper amount of positive ions have no side effect on a human body, and the plasma generator is allowed to be carried out in a space with a person while purifying and sterilizing the air, and has no side effect on the human body.

The fan is a direct current fan.

The air pipe is made of metal and can be lengthened or shortened according to the size of a room in a hospital; the air pipe and the air pipe are connected by adopting a screw structure.

The control panel in the box body is provided with a liquid crystal display screen, and a sensor is arranged in the control panel and can display indoor temperature, humidity, air volume, time, PM2.5 parameters, PM10 parameters, formaldehyde parameters and VOC organic compound parameters; the control panel is provided with a purifying device switch, an air volume adjusting button, a timing setting button and a sleep mode setting button.

The remote controller of the purification system is an infrared remote controller, and can control the on-off, the air volume, the timing and the sleep mode of the purification equipment by operating the remote controller.

The air supply outlet is connected with the air pipe through a screw rod and is consistent with the ceiling level of a hospital room, and the attractiveness of the room is improved.
