Description

Technical Field

[0001] This utility model relates to the field of air purification and intelligent control technology, and in particular to an intelligent control air purification device. Background Technology

[0002] Currently, air purification equipment is mostly used in homes, offices, and industrial environments. Because air quality is affected by various factors and fluctuates significantly, traditional purification equipment typically operates in fixed modes, making it difficult to dynamically adjust to real-time environmental changes. In areas with severe air pollution, the equipment needs to operate at high loads for extended periods, leading to high energy consumption and shortened filter lifespan, while in areas with lighter pollution, over-purification may occur. Furthermore, user operation relies heavily on manual adjustments, resulting in low levels of intelligence and failing to meet the demands for convenience and accuracy. The limited integration of sensors and control systems in existing equipment leaves room for improvement in terms of functional expansion and user experience optimization. Therefore, a more intelligent and efficient control solution is urgently needed to enhance overall performance. Utility Model Content

[0003] The purpose of this utility model is to provide an intelligent control air purification device that solves the problems mentioned in the background art.

[0004] This invention is implemented as follows: an intelligent air purification device mainly consists of a purification chamber, a multi-stage filtration assembly housed within the chamber, a sensing module mounted on the top of the chamber, and an embedded control system. The bottom of the purification chamber has an air inlet, and the top has an air outlet. An airflow channel is formed between the inlet and outlet via a guide plate. A pre-filter, an activated carbon filter layer, and a high-efficiency filter are sequentially arranged within the airflow channel. The sensing module includes multiple sensor units, used to detect the concentration of particulate matter, gaseous pollutants, and temperature and humidity parameters in the air. The embedded control system is connected to the sensing module via a data cable and is linked to the drive components in the multi-stage filtration assembly via a control circuit.

[0005] The purification chamber features a double-layer structure: an outer metal layer and an inner sound-insulating material. The two layers are bolted together and filled with damping rubber to reduce operating noise. A removable dust filter is installed at the air inlet, connected to the purification chamber via clips for easy cleaning or replacement. The air deflector has an arc-shaped design, with both ends fixed to the inner wall of the purification chamber by screws. The arc-shaped surface is coated with a hydrophobic coating to prevent condensation buildup. The pre-filter is mounted behind the air deflector via a sliding rail. Positioning slots are located on both sides of the rail; the pre-filter is inserted into the slots and secured with a locking knob. The activated carbon filter layer consists of several honeycomb-shaped activated carbon blocks, which are fixed to a bracket behind the air deflector by elastic clips. The bracket is welded to the inner wall of the purification chamber. The high-efficiency filter is located at the end of the airflow channel and is fixed to the top of the purification chamber via a magnetic frame.

[0006] The sensor module is mounted on a mounting base at the top of the purification chamber, which is fixed to the center of the top of the chamber via a threaded connection. The particulate matter sensor in the module uses the laser scattering principle; its probe extends into the airflow channel through a through-hole in the mounting base, and a sealing ring ensures an airtight connection between the probe and the through-hole. The gaseous pollutant sensor uses an electrochemical detection principle; its sensing end is connected to the embedded control system via wires, and the sensing end is wrapped with a waterproof and breathable membrane to extend its service life. The temperature and humidity sensor is fixed to the side wall of the mounting base by adhesive bonding, with its sensing surface facing the air outlet of the airflow channel.

[0007] The embedded control system is installed in the control compartment at the rear of the purification chamber. The control compartment is connected to the purification chamber via a hinge for easy opening and maintenance. The embedded control system includes a main control chip, a signal processing module, and a drive module. The main control chip is connected to the sensor module via a data cable. The signal processing module filters and calibrates the data collected by the sensors before transmitting it to the main control chip. The drive module is connected to the fan in the multi-stage filtration assembly via a relay. The fan is installed behind the high-efficiency filter and fixed to the inner wall of the purification chamber with bolts. The fan speed is dynamically adjusted by the drive module according to the instructions of the main control chip, thereby changing the airflow volume within the airflow channel.

[0008] This invention uses a sensor module to monitor air quality parameters in real time, and an embedded control system automatically adjusts the fan speed and the working status of the filter components based on the monitoring data. When the particulate matter concentration is high, the main control chip issues a command to increase the fan speed, increase the airflow in the airflow channel, and simultaneously activate the deep filtration function of the high-efficiency filter. When the concentration of gaseous pollutants is low, the main control chip reduces the fan speed and decreases the frequency of use of the high-efficiency filter to extend its lifespan. Furthermore, the embedded control system allows users to remotely view air quality data and equipment operating status via a mobile application, and can receive updated control algorithms through a wireless communication module to optimize equipment performance.

[0009] This invention achieves a dynamic operating mode for air purification equipment through multi-stage filtration components, precise monitoring by a sensing module, and intelligent adjustment via an embedded control system. The double-layered structure of the purification chamber effectively reduces operating noise, while the application of an arc-shaped air guide plate and hydrophobic coating minimizes the impact of condensation on airflow. The sliding rails and magnetic frame design enhance the ease of filter replacement. The multiple sensor units in the sensing module work collaboratively to comprehensively reflect air quality conditions, and the modular design of the embedded control system facilitates future functional expansion and maintenance. This invention significantly reduces energy consumption and filter wear while improving air purification efficiency, meeting the needs of intelligent air purification equipment in homes, offices, and industrial environments.

[0014] This utility model provides an intelligent control air purification device, the overall structure of which is as follows: Figure 1As shown, the system includes a purification chamber 1, an air inlet 2, an air outlet 3, a sensor module 4, and a control chamber 5. The purification chamber 1 is the core component of the equipment, with an air inlet 2 at the bottom and an air outlet 3 at the top. An airflow channel is formed between the air inlet 2 and the air outlet 3 via a guide plate 9. A pre-filter 6, an activated carbon filter layer 7, and a high-efficiency filter 8 are arranged sequentially within the airflow channel. The sensor module 4 is installed at the top center of the purification chamber 1 and is fixed to the mounting base 15 via a threaded connection. The control chamber 5 is located at the rear of the purification chamber 1 and is hinged for easy opening and maintenance. The embedded control system is installed inside the control chamber 5 and includes a main control chip, a signal processing module, and a drive module. It is linked to the sensor module 4 and the fan 10 in the multi-stage filtration assembly via data cables.

[0015] The purification chamber 1 adopts a double-layer structure design, with an outer layer of metal and an inner layer of sound-insulating material. The two layers are fixed together with bolts and filled with damping rubber to reduce operating noise. A removable dust cover is installed at the air inlet 2, which is connected to the purification chamber 1 via clips for easy cleaning or replacement by the user. The guide plate 9 has an arc-shaped design, with both ends fixed to the inner wall of the purification chamber 1 by screws. The arc-shaped surface is coated with a hydrophobic coating to prevent condensation buildup. The pre-filter 6 is installed behind the guide plate 9 via a slide rail. Positioning grooves are provided on both sides of the slide rail; the pre-filter 6 is inserted into the positioning groove and secured with a locking knob. The activated carbon filter layer 7 consists of several honeycomb-shaped activated carbon blocks, which are fixed to a bracket behind the guide plate 9 by elastic clips. The bracket is connected to the inner wall of the purification chamber 1 by welding. The high-efficiency filter 8 is located at the end of the airflow channel and is fixed to the mounting groove on the top of the purification chamber 1 via a magnetic frame 11.

[0016] Installation details of sensor module 4 are as follows Figure 3 As shown, particulate matter sensor 12, gaseous pollutant sensor 13, and temperature and humidity sensor 14 are distributed on mounting base 15. Particulate matter sensor 12 uses the laser scattering principle; its probe extends into the airflow channel through a through hole on mounting base 15, and a sealing ring 16 ensures an airtight connection between the probe and the through hole. Gaseous pollutant sensor 13 uses the electrochemical detection principle; its sensing end is connected to the embedded control system via a wire, and the sensing end is wrapped with a waterproof and breathable membrane 17 to extend its service life. Temperature and humidity sensor 14 is fixed to the side wall of mounting base 15 by adhesive bonding, with its sensing surface facing the air outlet 3 of the airflow channel.

[0017] The embedded control system is installed inside the control compartment 5. The main control chip is connected to the sensor module 4 via a data cable. The signal processing module filters and calibrates the data collected by the sensors before transmitting it to the main control chip. The drive module is connected to the fan 10 via a relay. The fan 10 is installed behind the high-efficiency filter 8 and fixed to the inner wall of the purification chamber 1 with bolts. The speed of the fan 10 is dynamically adjusted by the drive module according to the instructions of the main control chip, thereby changing the airflow in the airflow channel. When the particulate matter concentration is high, the main control chip issues an instruction to increase the speed of the fan 10, increasing the airflow in the airflow channel and activating the deep filtration function of the high-efficiency filter 8. When the concentration of gaseous pollutants is low, the main control chip reduces the speed of the fan 10 and reduces the frequency of use of the high-efficiency filter 8 to extend the filter's lifespan.

[0018] During operation, air enters the purification chamber 1 through inlet 2, passes through the pre-filter 6 to remove large particles, then enters the activated carbon filter layer 7 to adsorb harmful gases. It then undergoes deep filtration through the high-efficiency filter 8 and is finally discharged from outlet 3. The sensor module 4 monitors air quality parameters in real time and transmits the data to the embedded control system's main control chip. Based on the data, the chip automatically adjusts the fan speed 10 and the operating status of the filter components. Users can remotely view air quality data and equipment operating status via a mobile application and receive updated control algorithms via the wireless communication module to optimize equipment performance.

[0019] The dual-layer structure of the purification chamber 1 effectively reduces operating noise. The application of the arc-shaped air guide plate 9 and the hydrophobic coating reduces the impact of condensate on airflow. The design of the slide rail and magnetic frame 11 improves the convenience of filter replacement. The multiple sensor units of the sensing module 4 work together to comprehensively reflect the air quality status. The modular design of the embedded control system facilitates subsequent function expansion and maintenance. The equipment is suitable for home offices and industrial environments, meeting the needs of intelligent air purification.

[0020] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0021] When using this smart air purifier in a home environment, first place the purification chamber 1 in a suitable location in the living room or bedroom, ensuring that the air inlet 2 and air outlet 3 are not obstructed to allow for smooth airflow. After the device is turned on, air enters the purification chamber 1 through the air inlet 2. When passing through the pre-filter 6, large particles such as dust and hair are initially intercepted, thus reducing the burden on subsequent filter components. Subsequently, the air enters the activated carbon filter layer 7, where the honeycomb activated carbon blocks remove harmful gases and odor molecules through adsorption, especially volatile organic compounds such as formaldehyde and benzene commonly found indoors. Finally, the air undergoes deep filtration through the high-efficiency filter 8, where fine particulate matter such as PM2.5 is further captured, and finally, clean air is discharged from the air outlet 3.

[0022] The particulate matter sensor 12 in sensing module 4 uses the laser scattering principle to monitor the concentration of particulate matter in the air in real time. Its probe extends into the airflow channel, enabling it to accurately collect data on the distribution of particulate matter in the air. Simultaneously, the gaseous pollutant sensor 13, based on the electrochemical detection principle, captures harmful gas molecules in the air and transmits the data to the main control chip via the signal processing module. The temperature and humidity sensor 14 continuously monitors changes in ambient temperature and humidity, providing users with more comprehensive air quality information. These sensors work together to ensure that the device can fully reflect the current air quality conditions.

[0023] The embedded control system dynamically adjusts the equipment's operating status based on data collected by the sensing module 4. When the particulate matter sensor 12 detects a high concentration of PM2.5 in the air, the main control chip sends a command to the drive module to increase the speed of the fan 10 to increase the airflow in the airflow channel, while simultaneously activating the deep filtration function of the high-efficiency filter 8, thereby quickly improving air quality. Conversely, when the gaseous pollutant sensor 13 detects a low concentration of harmful gases and suitable temperature and humidity, the main control chip reduces the speed of the fan 10 and decreases the frequency of use of the high-efficiency filter 8 to extend the filter's lifespan and reduce equipment energy consumption.

[0024] During operation, users can remotely view air quality data and device status via a mobile application. For example, when in the office, users can receive real-time data uploaded by the device via the wireless communication module and adjust the device's operating mode as needed. Furthermore, the device supports online updates to its control algorithm, allowing users to access optimized operating strategies at any time to improve performance.

[0025] The dual-layer structure of the purification chamber 1 effectively reduces noise generated during equipment operation. The damping adhesive filling between the outer metal layer and the inner sound insulation material further absorbs vibration energy, ensuring that the equipment will not disturb users' rest at night. The arc-shaped airflow deflector 9 not only optimizes the airflow path but also reduces the impact of condensation on airflow through a hydrophobic coating, ensuring stable operation of the equipment even in high humidity environments. The pre-filter 6 is installed via a sliding rail, allowing users to easily replace it simply by unlocking the knob; the high-efficiency filter 8 is fixed by a magnetic frame 11, and replacement is as simple and quick as removing the old filter and installing the new one.

[0026] In summary, this invention achieves a dynamic operating mode for air purification equipment through multi-stage filtration, precise monitoring by sensing modules, and intelligent adjustment by an embedded control system. The optimized structural design of the purification chamber 1 improves operating efficiency and user experience, while the collaborative operation of multiple sensor units in the sensing module 4 ensures comprehensive air quality monitoring. The modular design of the embedded control system facilitates future functional expansion. This invention significantly reduces energy consumption and filter wear while improving air purification efficiency, meeting the needs of homes, offices, and industrial environments for intelligent air purification equipment.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
