Description

Technical Field

[0001] The utility model relates to a high-efficiency purification device for air microbial pollution, which belongs to the technical field of environmental purification, microbial pollution control and health protection. Background Art

[0002] In the current field of air purification technology, traditional purification equipment mainly relies on physical filtration and chemical reactions to eliminate harmful components in the air. These systems, such as HEPA filtration systems and activated carbon filters, are highly efficient in removing particulate matter and organic volatiles, but are not always ideal when dealing with microbial contamination, especially viruses and bacteria. For example, HEPA filters can intercept particles larger than 0.3 microns, but their interception ability is significantly reduced for smaller virus particles.

[0003] In recent years, ultraviolet (UV) technology has been gradually introduced into the field of purification, including water and air purification, to improve the efficiency of killing microorganisms. UV-C lamps have strong bactericidal ability, and their wavelength is between 260 nm and 270 nm, which can effectively destroy the structure of microorganisms, thereby achieving a killing effect. However, UV light sources need to be used in unmanned environments to avoid damage to human skin and eyes, which limits their practicality in continuous and widespread applications, and equipment that improves the efficiency of killing microorganisms with the blessing of far-infrared has not yet appeared.

[0004] Although the above technologies have their own advantages, they still have some shortcomings. For example, the safety issues of UV technology and the cost and complexity of plasma technology have limited the widespread application of these technologies. In addition, traditional air purification equipment often cannot achieve efficient aerodynamic layout, resulting in uneven air circulation and localized purification effect (CN202410078929.X, a rotary air purification and deodorization device). Utility Model Content

[0005] In order to solve the problems existing in the prior art, the utility model provides an efficient and safe air microbial pollution purification device to overcome the limitations of existing air purification technology in microbial pollution treatment, especially in terms of sterilization efficiency, safety and aerodynamic layout optimization. By integrating far-infrared lamps, 254nm ultraviolet lamps and low-temperature plasma generators, and cleverly arranging them on a rotating platform, the purification efficiency of viruses, bacteria and other microorganisms in the air can be effectively improved. The device adopts a color-changing heat-insulating glass shell, and adjusts the transparency to ensure safety in artificial conditions and high efficiency in non-artificial conditions. At the same time, intelligent sensors and two-way fans are used to monitor the environment and change the air flow mode. 360° grille-type inlet and outlet are used to ensure the uniformity of the return air, ensuring effective and uniform air purification in a variety of environments such as home, medical and office.

[0006] The utility model solves the technical problem by adopting the following technical scheme: an efficient air microbial pollution purification device, comprising a base and a top plate, a rotating base is arranged on the base, and a rotating platform is fixedly connected to the rotating base; a bottom temperature and ozone sensor and a low-temperature plasma generator are arranged at the end of the rotating platform through the rotating base, and a far-infrared lamp and a 254nm ultraviolet lamp are fixedly arranged on the rotating platform; the rotating base drives the rotating platform to rotate, driving the far-infrared lamp and the 254nm ultraviolet lamp to rotate; a two-way fan is arranged below the top plate through a fan connecting rod, and a top temperature and ozone sensor is arranged at the end of the fan connecting rod; a microwave human body induction module is arranged above the top plate;

[0007] An upper air vent, a discoloration heat-insulating glass shell, and a lower air vent are arranged in order from top to bottom between the top plate and the base; and a microwave human body induction module is matched with the discoloration heat-insulating glass shell.

[0008] The device is also provided with a controller, which is electrically connected with a top temperature and ozone sensor, a bottom temperature and ozone sensor, a low-temperature plasma generator, a far-infrared lamp, a 254 nm ultraviolet lamp, a bidirectional fan, and a rotating base.

[0009] The upper air vents and the lower air vents are annular grille-shaped air vents with a 360° opening.

[0010] The bidirectional fan can adjust the wind direction according to actual needs and has two air supply and return modes: upward delivery and downward return and downward delivery and upward return.

[0011] The color-changing heat-insulating glass shell can change color according to whether there is someone in the disinfection space. When there is someone, the color is changed to block the ultraviolet rays from propagating to the outside space, and when there is no one, it returns to transparency to release the ultraviolet rays from propagating to the outside space.

[0012] The beneficial effects of the utility model are:

[0013] The core of this utility model is to provide an integrated multifunctional air microbial pollution efficient purification device, which significantly improves the efficiency of removing microbial pollution in the air by combining multiple sterilization technologies such as far-infrared lamps, 254nm ultraviolet lamps and low-temperature plasma generators. Compared with the existing technology, this utility model has many technical advantages and positive effects.

[0014] First, the utility model can effectively destroy the microbial structure by using far-infrared lamps and ultraviolet lamps, thereby achieving the purpose of quickly killing bacteria and viruses. At the same time, the use of ultraviolet lamps is often restricted by human safety in traditional technologies, while the color-changing heat-insulating glass shell used in the device can automatically / manually adjust the transparency according to whether someone is rotating it, thereby protecting human safety, which is a significant innovation in the prior art.

[0015] Secondly, the addition of a low-temperature plasma generator enables the device to generate a large number of active particles at room temperature, effectively decomposing and removing bacteria and viruses in the air, rather than just physically blocking them. The application of this technology improves purification efficiency while also reducing the frequency of filter material replacement and subsequent maintenance costs.

[0016] Furthermore, the aerodynamic design of the utility model also performs well. The 360-degree annular grille air outlet and the adjustable two-way fan ensure the uniform flow of air inside the device and the all-round purification effect. This design optimizes the distribution of air flow, thereby improving the overall purification efficiency.

[0017] Finally, the intelligent monitoring and control system of the equipment is also an important innovation. Through the built-in temperature and ozone sensors, the equipment can monitor the air quality and equipment operating status in real time, and automatically adjust the operating parameters according to environmental changes, such as the speed of the rotating platform, to ensure that the equipment is always operating in the optimal state, which is rare in existing technologies.

[0018] In general, the beneficial effect of the utility model is that it provides a safe, efficient and intelligent air purification solution, which can significantly improve indoor air quality, reduce health risks caused by microorganisms, while reducing maintenance costs and operational complexity, and meet the high standards of modern life for health and environmental protection.

DETAILED DESCRIPTION

[0024] The following is a specific implementation of the utility model of the high-efficiency purification device for air microbial pollution, which describes in detail the configuration and function of each component to achieve the above-mentioned beneficial effects.

[0025] In order to solve the shortcomings of current technologies and products, the utility model proposes an air microbial pollution purification device

[0026] The upper air vent 1 and the lower air vent 11 are 360° open annular grille-shaped air vents to ensure uniform air supply and return. By adjusting the wind direction of the two-way fan 2, two 360° air supply and return, upper supply and lower return and lower supply and upper return, can be achieved. The upper air vent 1 and the lower air vent 11 can both function as air supply vents or air return vents. The far-infrared lamp tube 4 and the 254nm ultraviolet lamp tube 5 are arranged on the rotating platform, and the low-temperature plasma generator 6 is arranged at the center point of the rotating base. When the equipment is running, the energy-saving, normal and high-efficiency modes can be selected according to the sterilization efficiency requirements, which correspond to only turning on the 254nm ultraviolet lamp tube 5, the fan and the rotating platform at low wind speed; turning on the 254nm ultraviolet lamp tube 5 and the low-temperature plasma generator 6, the fan and the rotating platform at medium wind speed; turning on the far-infrared lamp tube 4, the 254nm ultraviolet lamp tube 5 and the low-temperature plasma generator 6, the fan and the rotating platform at high wind speed.

[0027] 0024 The color-changing heat-insulating glass shell 7 can change color according to whether there is someone in the disinfection space. The color-changing mode can be selected to be automatic or manual, and the manual mode has a higher priority than the automatic mode. It can change color when there are people to block the ultraviolet light from propagating to the outside space, and restore transparency when there is no one to release the ultraviolet light to propagate to the outside space.

[0028] The top temperature and ozone sensor 3 and the bottom temperature and ozone sensor 8 can monitor the temperature of the air inlet and outlet and the by-product (ozone) of the low-temperature plasma equipment. The far-infrared lamp 4 is stopped after the temperature reaches the temperature threshold, and it can be allowed to be turned on after the temperature is lower than the temperature threshold; the low-temperature plasma generator 6 is stopped after the ozone reaches the ozone threshold, and it can be allowed to be turned on after the ozone is lower than the ozone threshold. The sampling time interval of the top temperature and ozone sensor 3 and the bottom temperature and ozone sensor 8 is 1 time / min. The rotating platform 9 can adjust its rotation speed according to the disinfection efficiency requirements. Its rotation speed is proportional to the fan speed. For example, taking into account both operation stability and disinfection efficiency, the ratio is set to between 1:50-1:100.

[0029] The tops of the temperature and ozone sensor 3, the far-infrared lamp 4, the 254nm ultraviolet lamp 5, the low-temperature plasma generator 6 and the temperature and ozone sensor 8 are all designed in an arc shape, and the far-infrared lamp 4, the 254nm ultraviolet lamp 5, the low-temperature plasma generator 6 are all designed in a vertical direction. This is to prevent dust or other foreign matter from scattering or staying on the surface of the core equipment, affecting the sterilization effect and operational safety.

[0030] For a comprehensive understanding, the device stereogram, front view, side view and top view of the embodiment are shown as follows: Figure 1 , Figure 2 , Figure 3 and Figure 4 shown.

[0031] Structural composition

[0032] 1.1 Color-changing heat-insulating glass housing 7 and microwave human body induction module 12:

[0033] The color-changing heat-insulating glass shell 7 is composed of ordinary glass and intelligent light-controlled photochromic heat-insulating film (purchased from Tmall Sunice Bingyang flagship store). The microwave human body sensing module 12 adopts an existing product (microwave human body sensing module 24G 24.125gCDM324, purchased from Shenzhen Tengwei Environmental Protection Technology Co., Ltd.).

[0034] Function: According to the data of the microwave human body sensing module 12, it changes color when there are people to prevent ultraviolet rays from harming the human body; it returns to transparency when there are no people, allowing ultraviolet rays to pass through and improving the sterilization efficiency; the color change can also be controlled by remote control.

[0035] 1.2 Upstream outlet 1 and downstream outlet 11:

[0036] Structure: 360° open annular grille design.

[0037] Function: Ensure uniform air intake and exhaust, and achieve all-round air purification.

[0038] 1.3 Bidirectional fan 2:

[0039] Settings: Adjustable fan, the wind direction can be adjusted according to actual needs.

[0040] Function: It can realize two air supply and return modes: upward delivery and downward return and downward delivery and upward return, to optimize air flow.

[0041] 1.4 Rotating platform 9 and rotating base 10:

[0042] Structure: The rotating platform is located in the center of the equipment, and the rotating base supports the entire platform.

[0043] Function: Adjust the rotation speed to meet different disinfection efficiency requirements and ensure the effective operation of core components.

[0044] 1.5 Far infrared lamp 4, 254nm ultraviolet lamp 5 and low temperature plasma generator 6:

[0045] Arrangement: Arranged in sequence on a rotating platform, with the low-temperature plasma generator located at the center point.

[0046] Function: Far infrared lamps and ultraviolet lamps provide sufficient light to destroy microbial DNA, and low-temperature plasma generators produce a large number of active particles to enhance the air purification effect.

[0047] 1.6 Top temperature and ozone sensor 3 and bottom temperature and ozone sensor 8:

[0048] Position: One is installed diagonally on the rotating base and the other is placed at the bottom of the bidirectional fan.

[0049] Function: Monitor the temperature and ozone level at the air inlet and outlet to ensure the equipment is operating in a safe and effective state.

[0050] Operation process

[0051] Start the device: Turn on the power and the device will automatically perform a self-check, including sensor status and fan function.

[0052] Air purification: Depending on whether there is someone in the room, the glass shell automatically adjusts the transparency or is manually operated. The fan adjusts the wind direction, wind speed and sterilization mode according to the preset or actual needs. The ratio of the rotating platform speed to the fan speed is 1:50. After the setting is completed, the air is inhaled from the upper air outlet 1 or the lower air outlet 11 for purification.

[0053] In order to adapt to different sterilization needs, three operating modes are designed, namely energy-saving mode, normal mode and high-efficiency mode, allowing users to choose the most suitable working mode according to specific disinfection needs and scenarios.

[0054] Real-time monitoring and adjustment: The sensor monitors the temperature and ozone level in real time at a frequency of 1 time / min. When the temperature is higher than 60°C, the far-infrared lamp 4 is turned off, and it is restarted when it is lower than 45°C. When the ozone concentration is higher than 0.16 mg / m³, the low-temperature plasma generator 6 is turned off, and it is restarted when it is lower than 0.10 mg / m³. The above scheme ensures continuous and safe operation.

[0055] Air output: The purified air is evenly distributed back into the room through the downwind vent 11 / upwind vent 1.

[0056] Through this implementation, the utility model can provide an efficient, safe and intelligent air purification solution, which is suitable for various environments that require strict control of air quality.

[0057] The following are three embodiments: Example 1

[0058] Energy-saving mode: The fan and the rotating platform maintain low wind speed (200 rpm for the fan and 4 rpm for the rotating platform), with air sent upward and returned downward. At the same time, only the 254nm UV lamp 5 is turned on. When the microwave human body sensing module 12 detects someone, the color-changing heat-insulating glass shell 7 changes color to block ultraviolet rays. This mode is suitable for daily air purification needs, mainly for basic UV disinfection of bacteria and viruses in the air, and is suitable for use in environments with fewer people or low microbial pollution; Example 2

[0059] Normal mode: The fan and the rotating platform maintain low wind speed (fan 400 rpm, rotating platform 8 rpm), send air downward and upward, turn on the 254nm ultraviolet lamp 5 and the low-temperature plasma generator 6 at the same time, the microwave human body sensing module 12 does not detect anyone, the color-changing heat-insulating glass shell 7 changes to transparent, and releases ultraviolet rays. In this mode, the low-temperature plasma can enhance the disinfection effect of the ultraviolet lamp, and more effectively destroy the microbial structure through dual effects. This mode is suitable for environments that require enhanced disinfection, such as the flu season or in crowded indoor spaces; Example 3

[0060] High efficiency mode: The fan and rotating platform have low wind speed (600 rpm for the fan and 12 rpm for the rotating platform), with upward and downward transmission, and the far-infrared lamp 4, 254nm ultraviolet lamp 5 and low-temperature plasma generator 6 are turned on at the same time. The color-changing heat-insulating glass shell 7 is changed to transparent by remote control. At this time, the detection result of the microwave human body sensing module 12 does not work, and ultraviolet and infrared rays are released. The addition of the low-temperature plasma generator can produce a large number of active particles, which can not only attack and destroy the cell structure of microorganisms, but also further decompose and remove TVOC and odor in the air, providing the strongest air purification effect. This mode is most suitable for use in an unmanned state, especially in occasions where thorough disinfection is required, such as indoor environments after gathering of people, medical scenes or laboratories.

[0061] The above are only specific embodiments of the utility model patent, but the technical features of the utility model are not limited to them. Any simple changes, equivalent replacements or modifications made based on the utility model patent to solve basically the same technical problems and achieve basically the same technical effects are all covered by the protection scope of the utility model.
