Description

Technical Field

[0001] The utility model belongs to the field of air circulation, and particularly relates to an air circulation device for a closed space. Background Art

[0002] With the progress of technology and the improvement of people's requirements for environmental quality, the technology of air circulation devices is also constantly developing and improving. In the future, this field will pay more attention to the improvement of energy efficiency ratio, the application of intelligent control technology, and the research and application of environmental protection materials. At the same time, with the popularization and development of the Internet of Things technology, air circulation devices will become more intelligent and convenient, providing people with a more comfortable, healthy, and energy-saving indoor environment.

[0003] Some air circulation devices for closed spaces have been specifically developed in the prior art. For example, the Chinese patent with the publication number "CN211322290U" discloses "an air circulation device" which, through an internally installed activated carbon tube and a mixing auxiliary mechanism, has a suction pump connected to the right end of the air inlet, and a trachea is installed at the right end of the suction pump. The outside of the internally installed activated carbon tube is provided with a box body, and the internally installed activated carbon tube is located at the right end of the trachea. A support rod is arranged inside the internally installed activated carbon tube, and a humidifying mechanism is arranged at the upper right end of the internally installed activated carbon tube. During the use of the device, by using the spiral structure of the internally installed activated carbon tube, the air is relatively fully circulated, filtered, and purified, impurities contained in the air are removed, the air purification effect is improved, and further the air treatment and purification efficiency of the device is also improved.

[0004] Although the quality of the air can be improved through the activated carbon tube and the humidifier, during use, since the activated carbon tube is fixedly installed on the outer ring of the fixed rod, after long-term use of the activated carbon, more dirt and microorganisms will accumulate on the surface area of the activated carbon, resulting in a gradual reduction in the available pores of the material. These blocked pores will reduce the adsorption capacity of the activated carbon, causing its purification effect to decline, which will lead to the failure of the function of the activated carbon. Therefore, the activated carbon needs to be replaced regularly. However, the above content cannot effectively achieve the function of replacing the activated carbon. Since the activated carbon tube is fixed on the outer ring of the fixed rod, it will be very laborious to replace, and the effect of conveniently disassembling the activated carbon cannot be achieved.

[0013] As a preferred technical solution, a connecting pipe is fixedly installed at one end of the humidifier.

A handle is fixedly installed at the end of the first mounting plate away from the second activated carbon plate.

[0015] In summary, the present utility model mainly has the following beneficial effects:

[0016] First, when in use, the air in the closed space is sucked into the air suction pipe by the suction fan. As the suction fan rotates, the air will continue to flow into the air suction pipe. When the air passes through the air suction pipe, it will pass through the first activated carbon plate slidably installed inside the air suction pipe, and the air will be filtered by the first activated carbon plate, so that the stains remaining in the air are adsorbed by the first activated carbon plate. Then the air will flow along the air suction pipe into the U-shaped pipe. When passing through the inside of the U-shaped pipe, the air will also pass through the second activated carbon plate slidably installed inside the U-shaped pipe. In this way, the air will be filtered twice to improve the air quality. Since the first activated carbon plate and the second activated carbon plate are slidably installed inside the air suction pipe and the U-shaped pipe, the first activated carbon plate and the second activated carbon plate can be pulled out by the handle installed on one side of the first mounting plate and the second mounting plate for later replacement, which can effectively improve the installation and disassembly effect and can also improve the air filtering effect for a long time.

[0017] Second, when the air passes through the U-shaped pipe, it will continue to flow along the shape of the U-shaped pipe. When the air is about to enter the air outlet pipe, it will be wetted by the humidifier installed at the upper end of the air outlet pipe. A connecting pipe is fixedly installed at one end of the humidifier, and the end of the connecting pipe away from the humidifier passes through the side of the U-shaped pipe and extends into the U-shaped pipe. In this way, when the air passes through the connecting pipe, the connecting pipe will discharge water mist to wet the air, and can also effectively humidify the air and play a filtering role. Then the air will cause the water mist to flow into the air outlet pipe. The air outlet fan fixedly installed inside the air outlet pipe will discharge the humidified air. When the air passes through the air outlet pipe, it will enter the area of the mixing and stirring blades, and then the first motor is started to drive the rotating rod to rotate by the first motor. In this way, the mixing and stirring blades will rotate, and the air and the humidified water mist will be further mixed, so as to further improve the air quality.

[0018] Thirdly, when air passes through the mixing and stirring blades, it will enter the last filtration process. The air that has been mixed and stirred will be driven by the outlet fan and brought into the stainless steel filter screen. In this way, the air will be filtered more strongly, and the stains inside the air will adhere to the stainless steel filter screen, which can effectively improve the air quality and provide good air for the enclosed space. Since the stainless steel filter screen can also be quickly disassembled, the convenient disassembly effect of the stainless steel filter screen will also be improved during cleaning and maintenance, and the impurities and stains on the stainless steel filter screen can be effectively cleaned to prevent the stainless steel filter screen from being blocked. Finally, the air will be discharged from the outlet fan to achieve an effective circulation effect. BRIEF DESCRIPTION OF THE DRAWINGS
