Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air purification, in particular to an intelligent air purification anti-condensation system and method based on the Internet of Things. BACKGROUND

[0002] In many scenarios such as daily life and industrial production, air quality and equipment anti-condensation are of great importance. Traditional air purification systems mainly focus on filtering and purifying particulate matter, harmful gases and other substances in the air, but there are obvious deficiencies in dealing with air condensation problems.

[0003] Air condensation usually occurs in environments with low temperature and high humidity. When water vapor in the air encounters cold and reaches saturation, it will condense into liquid water. In traditional air purification systems, there is a lack of effective anti-condensation mechanism. Condensation not only affects the normal operation of air purification equipment and reduces its service life, but also can cause internal circuit short circuit, component corrosion and other serious problems, thereby affecting the stability and reliability of the entire system. In some large shopping malls, underground garages and other places, air purification equipment is used, which is prone to condensation due to high humidity and frequent temperature changes, resulting in frequent equipment failures, increased maintenance costs and downtime.

[0004] At present, although there are some technologies and equipment for anti-condensation, most of them have the problems of single function and low intelligence. Some simple anti-condensation methods, such as using heating devices to heat the air, can prevent condensation to some extent, but cannot achieve air purification and sterilization at the same time, and cannot meet the high requirements of modern people for air quality.

[0005] In addition, existing anti-condensation equipment usually lacks effective monitoring and control systems, and cannot automatically adjust the working state according to real-time air parameters, resulting in energy waste and poor anti-condensation effect. SUMMARY

[0006] To solve the above problems, the present application provides an intelligent air purification anti-condensation system and method based on the Internet of Things.

[0007] To achieve the above object, the application provides the following technical scheme: a smart air purification and anti-condensation system based on the Internet of Things, comprising a filtering assembly, an anti-condensation mechanism and a sterilization mechanism arranged on a main body, the anti-condensation mechanism comprising an anti-condensation block arranged on an air inlet end of the main body, a dehumidification and heating assembly arranged in the anti-condensation block, and a control assembly arranged in the anti-condensation block to control the dehumidification and heating assembly to pressurize the air in a cooling and dehumidification state; when the air is adjusted for anti-condensation, the air enters the anti-condensation block through the air inlet end, the dehumidification and heating assembly cools and dehumidifies and heats one side of the air flowing through the anti-condensation block, and the control assembly synchronously controls the air in the cooling and dehumidification state to be cyclically pressurized and discharges the air cooled and dehumidified and heated to the sterilization mechanism in the main body for sterilization.

[0008] Preferably, the anti-condensation block is provided with an air inlet and an air outlet at the top end and the low end respectively, and the air inlet and the air outlet are in communication with a treatment cavity arranged in the anti-condensation block, the dehumidification and heating assembly comprises two partition blocks arranged in the treatment cavity in the vertical direction and symmetrically arranged with respect to the opening position of the air inlet, a refrigeration and heating element arranged in the partition block, a cooling and dehumidification block arranged on the opposite faces of the two partition blocks and located directly below the air inlet, and a heating block arranged on the end faces of the two partition blocks on the opposite sides, and the cooling and dehumidification block and the heating block are connected to the refrigeration and heating element.

[0009] Preferably, the refrigeration and heating element is a semiconductor refrigeration sheet arranged in the partition block, and the refrigeration end and the heating end of the semiconductor refrigeration sheet are connected to the cooling and dehumidification block and the heating block respectively.

[0010] Preferably, the control assembly comprises a control block arranged on the inner wall of the treatment cavity directly below the opening position of the air inlet, a control element arranged in the control block, two second sealing blocks symmetrically arranged with respect to the control block and slidingly and sealingly arranged on the bottom positions of different partition blocks, and a first sealing block slidingly and sealingly arranged in the air inlet directly above the control block, the control element controls the first sealing block to move upward in the vertical direction when the two second sealing blocks move close to each other, and the first sealing block moves downward in the vertical direction when the two second sealing blocks move away from each other.

[0011] Preferably, the control element comprises two horizontal control rods arranged vertically on the opposite end faces of the two second sealing blocks, a vertical control rod arranged in the vertical direction and having the top end connected to the first sealing block and the low end movably arranged in the control block, two horizontal rods arranged in the horizontal direction and having the adjacent ends rotatably connected to the symmetrically opposite sides of the low end of the vertical control rod, and a control structure arranged in the control block and controlling the vertical control rod to move in the vertical direction, the other ends of the two horizontal rods are rotatably connected to the adjacent ends of different horizontal control rods; when the two horizontal control rods are collinear, the two second sealing blocks are located below the outer sides of the two partition blocks, and the first sealing block is located directly below the air inlet.

[0012] Preferably, the control structure includes two control discs sleeved on the vertical control rod, a limiting spring sleeved on the vertical control rod and connected to different control discs at both ends, and two electromagnets disposed on opposite end faces of the two control discs. The two control discs are respectively fixedly disposed on the vertical control rod and the control block. When the limiting spring is in the normal extended state, the first sealing block is sealed through the air inlet opening.

[0013] A smart air purification and anti-condensation method based on the Internet of Things includes the following steps:

[0014] Step 1: Receive the system start command via the Internet of Things to control the air intake of the main body to open, allowing outside air to enter the air intake of the anti-condensation block.

[0015] Step 2: Activate the dehumidification and heating component. The semiconductor cooling chip operates, and its cooling end cools down the dehumidification block to cool and dehumidify the air flowing through the anti-condensation block. At the same time, the heating end heats up the heating block to heat the air.

[0016] Step 3: The control components operate synchronously.

[0020] The second step is to transmit the monitored parameters to a remote control terminal or the system's local control center via the Internet of Things.

[0021] The third step involves automatically adjusting the working power of the dehumidification and heating components and the actions of the control components through the Internet of Things, based on the comparison results between the monitored parameters and the preset parameters, to achieve intelligent regulation of the air purification and anti-condensation process.

[0022] The beneficial effects of this invention are:

[0023] 1. After the air enters the main unit, it first passes through the filter component to remove particulate matter and other impurities. Then, the air is cooled, dehumidified, and heated by the anti-condensation mechanism to effectively prevent condensation. Finally, the treated air is delivered to the sterilization mechanism for sterilization, providing users with clean, dry, and sterile high-quality air, meeting the diverse needs of modern people for air quality.

[0024] 2. The anti-condensation mechanism employs a unique structural design, achieving precise anti-condensation treatment of the air through the coordinated operation of the dehumidification and heating components and the control component. The semiconductor cooling chip in the dehumidification and heating component can simultaneously achieve cooling and dehumidification functions, while the control component can circulate and pressurize the air in the cooling and dehumidification state according to the actual air conditions, further improving the dehumidification effect and effectively preventing the occurrence of air condensation.

[0033] To make the technical means, creative features, achieved objectives, and effects of this invention readily understandable, the invention is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this invention and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention.

[0034] Example 1: Reference Figures 1-6 The illustrated intelligent air purification and anti-condensation system based on the Internet of Things includes a filter assembly, an anti-condensation mechanism, and a sterilization mechanism mounted on a main body 1. The main body 1 has an air inlet 2 and an exhaust 3. The anti-condensation mechanism includes an anti-condensation block 4 mounted on the air inlet 2 of the main body 1, a dehumidification and heating assembly mounted inside the anti-condensation block 4, and a control assembly mounted inside the anti-condensation block 4 that controls the operation of the dehumidification and heating assembly and pressurizes the air in a cooling and dehumidification state. When the air is regulated to prevent condensation, the air enters the anti-condensation block 4 through the air inlet 2. The dehumidification and heating assembly cools, dehumidifies, and heats one side of the air flowing through the anti-condensation block 4. The control assembly simultaneously controls the air in the cooling and dehumidification state to circulate and pressurize, and discharges the cooled, dehumidified, and heated air to the sterilization mechanism inside the main body 1 for sterilization.

[0035] In this embodiment, under the drive of the system operation command, outside air enters the anti-condensation block 4 through the air inlet 2 of the main body 1. At this time, the air begins its purification and anti-condensation journey within the system. The air inlet 2, as the primary channel for air to enter the system, directly affects the efficiency and flow rate of air entry due to its rational design and unobstructed flow.

[0036] When air enters the anti-condensation block 4, the dehumidification and heating component installed inside it begins to function. The cooling and heating element (such as the semiconductor cooling chip 10) within the component activates, its cooling end lowering the temperature of the dehumidification block. As air flows past one side of the dehumidification block, water vapor in the air condenses into liquid water upon contact with the cold surface, thus achieving the purpose of cooling and dehumidification. Simultaneously, the heating end of the cooling and heating element raises the temperature of the heating block, heating the air after it has been cooled and dehumidified. This process not only removes moisture from the air and prevents condensation, but also regulates the air temperature, ensuring that the emitted air has a suitable temperature.

[0037] While the dehumidification and heating components are operating, the control components also begin to run synchronously. The controllers within the control components, based on preset programs or real-time air parameters (such as humidity and pressure) received via the Internet of Things, control the movement of the two second sealing blocks 12 and the first sealing block 6. When the two second sealing blocks 12 approach each other, the first sealing block 6 moves upwards in the vertical direction; when the two second sealing blocks 12 move away from each other, the first sealing block 6 moves downwards in the vertical direction. This coordinated movement creates a process of cyclically pressurizing the air in the cooling and dehumidification state. Through cyclic pressurization, the contact effect between the air and the cooling / dehumidification blocks and heating blocks is further improved, enhancing the efficiency of dehumidification and heating, and ensuring that the air is fully processed.

[0038] The air, after being cooled, dehumidified, and heated, is discharged into the sterilization mechanism inside the main body 1 through the exhaust port 17 of the anti-condensation block 4. The sterilization mechanism uses appropriate methods (such as ultraviolet sterilization, plasma sterilization, etc.) to sterilize the air, removing harmful microorganisms such as bacteria and viruses, ultimately providing users with clean, dry, and sterile high-quality air.

[0039] The air inlet 5 of the anti-condensation block 4 is provided with a limiting ring 7 to prevent the first sealing block 6 from moving above the air inlet 5.

[0040] It is understandable that air can be cooled, dehumidified, and heated in various ways. This embodiment provides the following solution:

[0041] like Figure 5 As shown, the anti-condensation block 4 has an air inlet 5 and an exhaust port 17 at its top and bottom, respectively, and both the air inlet 5 and the exhaust port 17 are connected to the processing cavity 8 inside the anti-condensation block 4. The dehumidification and heating assembly includes two partitions 9 arranged vertically in the processing cavity 8 and symmetrically arranged about the opening position of the air inlet 5, a cooling and heating element arranged in the partitions 9, a cooling and dehumidification block arranged on the opposite surface of the two partitions 9 and located directly below the air inlet 5, and a heating block arranged on the opposite end face of the two partitions 9. The cooling and dehumidification block and the heating block are connected to the cooling and heating element.

[0042] In this embodiment, after air enters the processing chamber 8, the cooling and heating elements located within the partitions 9 begin to operate. These elements have both cooling and heating functions; the cooling end lowers the temperature of the dehumidifying block, while the heating end raises the temperature of the heating block. The two partitions 9 are vertically positioned within the processing chamber 8 and symmetrical about the opening of the air inlet 5. The dehumidifying block located directly below the air inlet 5 experiences a temperature reduction due to the cooling end. When air flows through the dehumidifying block, water vapor in the air condenses into liquid water upon contact with the condenser, adhering to the surface of the dehumidifying block or dripping to the bottom of the processing chamber 8. This effectively removes moisture from the air, reducing the relative humidity and preventing condensation. A drainage structure is included to discharge the dehumidified liquid water. Simultaneously, the heating blocks located on opposite ends of the two partitions 9 experience a temperature increase due to the heating end. The dehumidified air continues to flow, contacting and being heated by the heating blocks. The increased air temperature after heating further reduces the relative humidity and brings the air to a suitable temperature, preventing the risk of condensation due to excessively low temperatures. While the dehumidification and heating components are operating, the control components also come into play. The controllers within the control components, based on preset programs or real-time air parameters (such as humidity and pressure) received via the Internet of Things, control the movement of the two second sealing blocks 12 and the first sealing block 6. When the two second sealing blocks 12 approach each other, the first sealing block 6 moves upwards in the vertical direction; when the two second sealing blocks 12 move away from each other, the first sealing block 6 moves downwards in the vertical direction. This coordinated movement creates a cyclical pressurization process for the air undergoing cooling, dehumidification, and heating. This cyclical pressurization increases the contact time and effectiveness between the air and the cooling / dehumidification and heating blocks, enhancing the efficiency of dehumidification and heating and ensuring that the air is fully treated.

[0043] It is understandable that various structures can be used as heating and cooling sources. This embodiment provides the following solution:

[0044] like Figure 5 As shown, the cooling and heating element is a semiconductor cooling chip 10 disposed in the partition 9. The cooling end and the heating end of the semiconductor cooling chip 10 are respectively connected to the cooling and dehumidifying block and the heating block.

[0045] It is understandable that air in a cooling and dehumidifying state can be circulated and pressurized in various ways. This embodiment provides the following solution:

[0046] like Figures 4-6As shown, the control assembly includes a control block 11 located on the inner wall directly below the opening of the air inlet 5 within the processing chamber 8, a control element located within the control block 11, two second sealing blocks 12 symmetrically arranged about the control block 11 and slidably sealed at the bottom positions of different partitions 9, and a first sealing block 6 located directly above the control block 11 and slidably sealed through the air inlet 5. When the control element controls the two second sealing blocks 12 to move closer to each other, the first sealing block 6 moves upward in the vertical direction; when the two second sealing blocks 12 move further apart, the first sealing block 6 moves downward in the vertical direction.

[0047] In this embodiment, when the second sealing blocks 12 move closer together and the first sealing block 6 moves upward, the air in a portion of the processing chamber 8 is compressed, increasing the pressure. This pressure change causes the air to pass through the cooling and dehumidifying blocks more quickly, enhancing the efficiency of cooling and dehumidification. Simultaneously, the compressed air, during its flow, exerts a certain pushing effect on the subsequently entering air, creating a circulating flow. When the second sealing blocks 12 move further apart and the first sealing block 6 moves downward, the pressure distribution within the processing chamber 8 changes again. The air continues to circulate under the influence of the pressure difference and comes into full contact with the heating blocks for heating. This cyclical pressurization process not only increases the contact time and effectiveness between the air and the processing components but also enhances the mixing degree of the air within the processing chamber 8, resulting in more uniform temperature and humidity in the processed air and improving the overall air treatment quality of the system.

[0048] like Figure 5 As shown, the control unit includes two horizontal control rods 13 that are perpendicularly arranged on opposite end faces of the two second sealing blocks 12 at opposite ends, a vertical control rod 14 that is arranged vertically and whose top end is connected to the first sealing block 6 and whose bottom end is movably inserted into the control block 11, two horizontal linkage rods 20 that are rotatably connected at their adjacent ends to the symmetrical sides of the bottom end of the vertical control rod 14, and a control structure arranged in the control block 11 that controls the vertical control rod 14 to move vertically. The other ends of the two linkage rods 20 are rotatably connected to adjacent ends of different horizontal control rods 13. When the two horizontal control rods 13 are collinear, the two second sealing blocks 12 are located below and outside the two partitions 9, and the first sealing block 6 is located directly below the air inlet 5.

[0049] This design in this embodiment allows the horizontal control rod 13 to move accordingly when the control structure drives the vertical control rod 14 to move vertically, via the transmission action of the linkage rod 20. When the vertical control rod 14 moves upward, the linkage rod 20 pulls the horizontal control rods 13 closer together; when the vertical control rod 14 moves downward, the linkage rod 20 pushes the horizontal control rods 13 away from each other. This mechanical linkage mechanism ensures that the first sealing block 6 and the two second sealing blocks 12 can move in a coordinated manner according to a predetermined pattern, achieving precise control.

[0050] Two horizontal control rods 13 are connected at one end to two adjacent ends of two linkage rods 20 via sliders 19. The two sliders 19 are slidably disposed within the control block 11, and the two sliders 19 can only slide closer to or further away from each other.

[0051] like Figure 5 and Figure 6 As shown, the control structure includes two control discs 16 sleeved on the vertical control rod 14, a limiting spring 15 sleeved on the vertical control rod 14 and connected to different control discs 16 at both ends, and two electromagnets 18 set on the opposite end faces of the two control discs 16. The two control discs 16 are respectively fixedly set on the vertical control rod 14 and the control block 11. When the limiting spring 15 is in the normal extended state, the first sealing block 6 seals the opening position of the air inlet 5.

[0052] In this embodiment, when one of the electromagnets 18 is energized, it generates a magnetic force that attracts the other control disk 16, thereby moving the vertical control rod 14. Since there are two electromagnets 18, by controlling their energization states separately, bidirectional movement of the vertical control rod 14 in the vertical direction can be achieved. When the upper electromagnet 18 is energized, it attracts the lower control disk 16, causing the vertical control rod 14 to move upward, which in turn moves the first sealing block 6 upward; when the lower electromagnet 18 is energized, it causes the vertical control rod 14 to move downward, and the first sealing block 6 also moves downward. This bidirectional driving capability provides the basis for precise control of the sealing block. A limiting spring 15 is sleeved on the vertical control rod 14, with its two ends connected to different control disks 16. The elastic force of the limiting spring 15 provides a certain resistance, giving the control disk 16 a certain buffering and stabilizing effect during movement. Meanwhile, by controlling the magnitude and duration of the energizing current of the electromagnet 18, the magnetic force of the electromagnet 18 can be precisely controlled, thereby precisely controlling the moving distance of the control disk 16, and thus achieving precise displacement of the first sealing block 6 in the vertical direction.

[0053] A smart air purification and anti-condensation method based on the Internet of Things includes the following steps:

[0054] Step 1: Receive the system start command via the Internet of Things to control the air intake 2 of the main body 1 to open, allowing outside air to enter the air intake 5 of the anti-condensation block 4.

[0055] Step 2: Start the dehumidification and heating component. The semiconductor cooling chip 10 works, and its cooling end cools down the dehumidification block to cool and dehumidify the air flowing through the anti-condensation block 4. At the same time, the heating end heats up the heating block to heat the air.

[0056] Step 3: The control components operate synchronously. The control components control the movement of the two second sealing blocks 12 and the first sealing block 6 according to the preset program or the real-time air parameters received through the Internet of Things, so as to circulate and pressurize the air in the cooling and dehumidification state.

[0057] Step four: The cooled, dehumidified and heated air is discharged through exhaust port 17 to the sterilization mechanism inside the main body 1 for sterilization treatment, thus completing the air purification and anti-condensation process.

[0058] It also includes air parameter monitoring and feedback steps:

[0059] The first step is to monitor the temperature, humidity, and pressure parameters of the air entering the anti-condensation block 4 in real time by setting temperature, humidity, and pressure sensors in the system.

[0060] The second step is to transmit the monitored parameters to a remote control terminal or the system's local control center via the Internet of Things.

[0061] The third step involves automatically adjusting the working power of the dehumidification and heating components and the actions of the control components through the Internet of Things, based on the comparison results between the monitored parameters and the preset parameters, to achieve intelligent regulation of the air purification and anti-condensation process.
