Technical Field

[0001] This utility model relates to the field of air purification technology, specifically to an air purification device for a medical purification area. Background Technology

[0002] Medical cleanrooms are areas within medical facilities where air quality (such as dust particles, microbial content, temperature, humidity, and airflow direction) is strictly controlled through special design and technology. The aim is to create a highly clean, safe, and stable medical environment, reduce the risk of infection, ensure the smooth operation of medical procedures, and facilitate patient recovery. Air purification devices for medical cleanrooms are specifically designed for these areas (such as operating rooms, intensive care units, and sterile wards) to ensure air quality.

[0003] However, existing technologies still have the following problems:

[0004] Some purification devices in cleanrooms have limited purification functions, relying solely on simple filtration methods, which are insufficient to effectively remove microorganisms and harmful gases from the air. Furthermore, most devices lack the ability to precisely regulate air temperature and humidity, failing to meet the special environmental requirements of medical cleanrooms. Moreover, most devices use fixed air outlet designs, making it impossible to flexibly adjust the exhaust volume according to actual needs, resulting in low purification efficiency and energy waste. Utility Model Content

[0005] To address the issues of limited purification functions and inability to adjust exhaust volume, the purpose of this invention is to provide an air purification device for medical purification areas.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an air purification device for a medical purification area, comprising a housing, wherein supports are symmetrically and fixedly installed on the lower surface of the housing, and an inspection door is symmetrically and rotatably connected to one side of the housing, an air inlet is provided on one side of the housing, and an air outlet is provided on the other side of the housing, an adjustment device is fixedly installed on one side of the air outlet, a support frame, a heat exchange device, a bracket, a fan, and a motor are fixedly installed inside the housing, the output end of the motor is drivenly connected to the fan, the adjustment device includes a connecting plate, one side of the connecting plate is fixedly connected to the air outlet, and a pipe is fixedly connected to the other side of the connecting plate, a rotating shaft is rotatably connected inside the pipe, a valve is fixedly sleeved on the outer surface of the rotating shaft, a side support plate is fixedly installed on the outer surface of one side of the pipe, and one end of the rotating shaft passes through the pipe and the side support plate and is fixedly sleeved with an adjustment rod.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Figure 1-5 As shown, this utility model provides an air purification device for a medical purification area, including a housing 11. Supports 10 are symmetrically fixedly installed on the lower surface of the housing 11 to firmly support the device on the ground and ensure operational stability. A maintenance door 14 is symmetrically rotatably connected to one side of the housing 11, facilitating access for maintenance, repair, and replacement of internal components. An air inlet 12 is provided on one side of the housing 11 as an air intake channel, and an air outlet 13 is provided on the other side as a purified air exhaust channel. An adjustment device 22 is fixedly installed on one side of the air outlet 13 to control the airflow and direction. Inside the housing 11, a support frame 15, a heat exchange device 16, a bracket 17, a fan 20, and a motor 21 are fixedly installed. The output end of the motor 21 is connected to the fan 20, and the output end of the fan 20 is fixedly connected to the air outlet 13. The motor 21 drives the fan 20 to generate suction and thrust, causing air to circulate within the housing 11.

[0019] Multiple grilles 24 are symmetrically arranged on the outer surface of the support frame 15, and two slide rails 25 are symmetrically fixedly installed on the inner surface. A high-efficiency filter plate 26 is slidably connected between the two slide rails 25 on the same vertical horizontal line. (The high-efficiency filter plate 26 is made of ultra-fine glass fiber, which can filter out most of the particles in the air with a diameter of 0.3 microns and smaller, including bacteria, viruses, etc.) The outer surface of the high-efficiency filter plate 26 slides and fits against the slide rail 25, and a handle is fixedly installed on one side. After the air enters from the air inlet 12, the grilles 24 block larger particles of impurities, and the high-efficiency filter plate 26 uses its fine structure to capture fine particles, bacteria and other pollutants. The staff can use the handle to pull it out along the slide rail 25 for cleaning or replacement to maintain the filtration effect.

[0020] The heat exchange device 16 includes a housing 27, and a heat exchange coil 28 is fixedly installed between the inner walls of the housing 27. One end of the heat exchange coil 28 has a fluid inlet 29 and the other end has a fluid outlet 30. After the air is preliminarily filtered, it enters and then the hot and cold fluids are introduced into the heat exchange coil 28 through the fluid inlet 29. The air exchanges heat with the heat exchange coil 28 to achieve precise regulation of air temperature and humidity.

[0021] A pressure water pipe 18 is fixedly installed on the outer surface of the bracket 17. A plurality of atomizing nozzles 19 arranged in a rectangular array are fixedly connected to one side of the pressure water pipe 18. One end of the pressure water pipe 18 passes through the box 11 and is fixedly connected to a water pump. When the purified air flows to this point, the water pump starts to deliver liquid to the pressure water pipe 18. The atomizing nozzles 19 convert the liquid into micron-sized droplets, which further purify the air and regulate humidity through physical adsorption and disinfection.

[0022] The regulating device 22 includes a connecting plate 31 fixedly connected to the air outlet 13. A pipe body 38 is fixedly connected to the other side of the connecting plate 31. A rotating shaft 32 is rotatably connected inside the pipe body 38. A valve plate 33 is fixedly sleeved on the outer surface of the rotating shaft 32, and the diameter of the valve plate 33 is the same as the inner diameter of the pipe body 38, with its outer surface slidingly fitting against the inner surface of the pipe body 38. A side support plate 34 is fixedly installed on one outer surface of the pipe body 38, and an arc-shaped groove 35 is formed on the outer surface of the side support plate 34. One end of the rotating shaft 32... An adjusting rod 36 is fixedly sleeved through the pipe body 38 and the side support plate 34. A connecting pin 37 is fixedly installed on the outer surface of the adjusting rod 36. The outer surface of the connecting pin 37 slides against the outer surface of the arc-shaped slide groove 35. The purified air flows to the air outlet 13 under the push of the fan 20. Rotating the adjusting rod 36 causes the connecting pin 37 to slide in the arc-shaped slide groove 35, causing the rotating shaft 32 to rotate, which in turn drives the valve plate 33 to rotate, changing the flow area of ​​the air outlet 13, thereby realizing the adjustment of the air flow rate and direction.

[0023] Working Principle: Motor 21 starts, driving fan 20 to operate and generate suction. Under the action of fan 20, outside air is drawn into housing 11 through air inlet 12. After entering the housing, the air first passes through support frame 15. Grille 24 on support frame 15 blocks larger particles, while high-efficiency filter plate 26, installed along slide rail 25, finely filters fine particles and bacteria in the air, ensuring relatively clean air entering subsequent stages. The pre-filtered air enters heat exchange device 16. Heat exchange coil 28 within heat exchange device 16 is circulated with hot or cold fluids such as water or refrigerant through fluid inlet 29 and fluid outlet 30, achieving heat exchange between air and fluid, regulating air temperature and humidity to meet the strict temperature and humidity requirements of medical environments. The air then... The water continues to flow to the support area 17. The pressure water pipe 18 is connected to an external water pump. When the water pump is working, the disinfectant water is delivered to the atomizing nozzle 19 through the pressure water pipe 18. The nozzle sprays the air with atomized water, and the disinfectant water is converted into micron-sized droplets. The droplets can evenly cover bacteria, viruses and dust particles in the air, and kill microorganisms through physical adsorption or chemical disinfection. At the same time, the evaporation of the droplets can help regulate the air humidity and enhance the filtration effect. After the above-mentioned filtration, temperature and humidity regulation, spraying and other purification treatments, the air is pushed to the air outlet 13 by the fan 20.

[0024] The adjustment device 22 at the air outlet 13 can adjust the air outlet. By rotating the adjustment rod 36, it slides in the arc-shaped slide groove 35 through the connecting pin 37, which drives the valve plate 33 to rotate around the rotating shaft 32, changing the opening of the air outlet by 13 degrees, controlling the air flow and direction, so that the purified air is delivered into the medical purification area as needed.

[0025] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
