Description

Technical Field

[0001] The utility model relates to the field of smart homes, and in particular to a household air purification device. Background Art

[0002] With the improvement of living standards, people have higher and higher requirements for indoor air quality. Therefore, smart home air purification equipment has become a popular product on the market. However, during long-term use, the dust in the smart home air purification equipment will gradually increase, resulting in a decrease in the filtering effect. Therefore, how to monitor the filtering status in real time and remind users to clean or replace the purification equipment when necessary has become an important issue facing smart home air purification equipment. Utility Model Content

[0003] The utility model aims to solve the problem of how to remind users to clean or replace filter equipment in time, and provides a household air purification device.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a household air purification device includes a filter box, an air inlet, a controller, two slide rails, a pressure sensor, a filter plate, a spring, a communication module, an open cover, a drive motor, a fan, and a purification component. The air inlet is arranged on the side of the filter box and is connected to the filter box. The controller is arranged on the outer surface of the filter box and is fixedly connected to the filter box. The two slide rails are respectively arranged horizontally on the top surface and the bottom surface inside the filter box, respectively perpendicular to the side of the filter box where the air inlet is located, and respectively fixedly connected to the filter box. The pressure sensor is arranged inside the filter box away from the air inlet, fixedly connected to the filter box, and electrically connected to the controller. The filter plate is arranged inside the filter box, arranged on the side of the pressure sensor, parallel to the side of the filter box where the air inlet is located, and slidably connected to the slide rail. The axis of the spring is parallel to the slide rail, and the spring is arranged inside the filter box, one end is fixedly connected to the pressure sensor, and the other end is fixedly connected to the filter plate. The communication module is arranged on the outer surface of the filter box, fixedly connected to the filter box, and the communication module is electrically connected to the controller. The opening cover is arranged on the top of the filter box, and is movably connected to the filter box, and the opening cover cooperates with the filter plate. The driving motor is arranged on the side of the filter box away from the air inlet, and is fixedly connected to the filter box, and is electrically connected to the controller. The output end of the driving motor passes through the filter box and extends to the inside of the filter box. The fan is arranged inside the filter box, arranged on the side of the filter plate, and is fixedly connected to the output end of the driving motor. The purification component is arranged on the side of the filter box close to the driving motor, and is connected to the filter box.

[0005] When the user turns on the air purification device, the controller starts the drive motor. The output end of the drive motor drives the fan to start rotating, forming an airflow. External air enters the filter box through the air inlet. The airflow first passes through the filter plate, which filters the dust in the air. As the filter plate continues to be used, the dust on it will gradually increase, causing the airflow through the filter plate to gradually weaken. Due to the obstruction of the airflow, the pressure difference on both sides of the filter plate will change. The pressure on the side of the filter plate close to the pressure sensor will gradually decrease, and the pressure on the side of the filter plate close to the air inlet will be higher than the pressure on the side of the filter plate close to the pressure sensor. The high pressure will push the filter plate to slide along the slide rail to the side close to the pressure sensor and compress the spring. The elastically deformed spring squeezes the pressure sensor at the other end of the spring. The pressure sensor senses the pressure change and converts the change into an electrical signal, which is then sent to the controller. After the controller receives the signal from the pressure sensor, the controller passes the instruction to the communication module. After receiving the instruction from the controller, the communication module sends a notification to clean or replace the filter plate to the user's mobile device through the network. After receiving the notification, the user opens the cover to replace the filter plate. After the air passes through the filter plate, it continues to flow to the purification component. At this time, the air has been initially filtered and most of the larger dust has been removed. Next, the air enters the purification component for further processing and purification. After the air purification is completed, it flows back to the outside. The combination of pressure sensors and springs can realize real-time monitoring of the filter plate status. And the communication module promptly notifies the user to clean or replace it, thereby ensuring that the air purification equipment works continuously and efficiently. The opening of the cover and the filter plate are coordinated, which means that after the user receives the notification, he opens the cover and replaces the filter plate.

[0006] Further: the purification component includes a purification box, a spray column, a water inlet, a water inlet pipe, a water leakage hole, an air outlet, and four supporting legs. The purification box is arranged on the side of the filter box close to the driving motor and is connected to the filter box. The spray column is vertically arranged inside the purification box, is connected to the purification box, and is fixedly connected to the purification box. The water inlet is arranged at the bottom of the spray column and is connected to the spray column. The water inlet pipe is arranged on the side of the purification box, one end of which is connected to the water inlet, and the other end is connected to the water source outside the purification box. The water leakage hole is arranged at the bottom of the purification box and is connected to the purification box. The air outlet is arranged on the side of the purification box away from the filter box and is connected to the purification box. The four supporting legs are respectively arranged at the four end feet at the bottom of the purification box and are fixedly connected to the purification box.

[0007] The air that has passed through the filter plate enters the purification box through the channel connecting the filter box and the purification box. Due to the previous filtering process, most of the larger dust has been removed from the air at this time. Inside the purification box, the water source enters the spray column through the water inlet pipe and sprays downward from the top of the spray column. In this process, the spray water contacts the passing air, and the gravity of the water droplets further removes the tiny dust in the air. When the water droplets combine with the dust in the air, the formed sewage is discharged through the leaking hole, thereby keeping the inside of the purification box clean. The air purified by the spray continues to flow and is discharged through the air outlet, and the purified air flows back into the room. Through the spray purification method, the tiny dust and harmful gases in the air can be effectively removed, providing users with a healthier and fresher indoor environment. The four supporting legs provide stable support for the purification box.

[0008] Further: it comprises a water-saving bucket. The water-saving bucket is arranged below the water leakage hole and matches with the water leakage hole.

[0009] When the leak hole at the bottom of the purification box discharges sewage, the sewage flows into the water-saving barrel. The sewage collected in the water-saving barrel can be reused or treated.

[0010] Further: including a primary filter layer, an activated carbon filter layer, a HEPA filter layer, and an antibacterial filter layer. The primary filter layer, the activated carbon filter layer, the HEPA filter layer, and the antibacterial filter layer are sequentially arranged on the side of the filter plate and fixedly connected to the filter plate.

[0011] When the outside air enters the filter box through the air inlet and passes through the filter plate, it first passes through the primary filter layer. The primary filter layer is mainly used to remove larger particles in the air, such as dust, hair, etc. The air that has passed the primary filter then enters the activated carbon filter layer. Activated carbon has a very high adsorption capacity and can remove harmful gases and odors in the air, such as organic compounds such as formaldehyde and benzene. Next, the air enters the HEPA (High Efficiency Particulate Air) filter layer. The HEPA filter layer can capture particles with a diameter of more than 0.3 microns, including tiny pollutants such as viruses, bacteria, and pollen. Finally, the air passes through the antibacterial filter layer. The antibacterial filter layer uses special materials or technologies that can inhibit or kill bacteria and other microorganisms passing through its surface. By combining the primary filter layer, activated carbon filter layer, HEPA filter layer, and antibacterial filter layer, the indoor air can be fully and efficiently purified to provide users with a healthy and fresh indoor environment.

[0012] Further: the opening cover is movably connected to the filter box through a hinge.

[0013] The cover is movably connected to the filter box via a hinge, which allows the cover to be turned over relative to the filter box, making it convenient for users to open and close the cover.

[0014] Further: The primary filter layer is made of metal mesh or synthetic fiber.

[0015] Metal mesh is strong, durable and easy to clean. Metal mesh is used to intercept larger particles, such as dust, hair, etc. Its mesh size can be adjusted as needed to achieve different filtering effects. Synthetic fiber is made of polymer, which is light, soft and easy to process. It can effectively remove larger particles in the air.

[0016] Beneficial effects of the utility model:

[0017] 1. Real-time monitoring of the filter plate status is achieved through the combined use of pressure sensors and springs. The user is notified in time through the communication module to clean or replace the filter plate, thereby ensuring that the air purification equipment works continuously and efficiently.

External air enters the filter box 16 through the air inlet 1. The airflow first passes through the filter plate 5, which filters the dust in the air. As the filter plate 5 continues to be used, the dust on it will gradually increase, causing the airflow through the filter plate 5 to gradually weaken. Due to the obstruction of the airflow, the pressure difference on both sides of the filter plate 5 will change. The pressure on the side of the filter plate 5 close to the pressure sensor 4 will gradually decrease, and the pressure on the side of the filter plate 5 close to the air inlet 1 is higher than the pressure on the side of the filter plate 5 close to the pressure sensor 4. The high pressure will push the filter plate 5 to slide along the slide rail 3 to the side close to the pressure sensor 4 and compress the spring 6. The elastically deformed spring 6 squeezes the pressure sensor 4 at the other end of the spring 6. The pressure sensor 4 senses the pressure change and converts the change into an electrical signal, and then sends these signals to the controller 2.

After receiving the notification, the user opens the cover 8 to replace the filter plate 5. After the air passes through the filter plate 5, it continues to flow to the purification component. At this time, the air has been preliminarily filtered and most of the larger dust has been removed. Next, the air enters the purification component for further processing and purification, and flows back to the outside world after the air purification is completed. Through the combined use of the pressure sensor 4 and the spring 6, real-time monitoring of the status of the filter plate 5 is achieved. And the user is promptly notified through the communication module 7 to clean or replace it, thereby ensuring that the air purification equipment works continuously and efficiently.

[0024] The air passing through the filter plate 5 enters the interior of the purification box 11 through the channel connecting the filter box 16 and the purification box 11. Due to the previous filtering process, most of the larger dust has been removed from the air at this time. Inside the purification box 11, the water source enters the spray column 12 through the water inlet pipe 14 and sprays downward from the top of the spray column 12. In this process, the spray water contacts the passing air, and the gravity of the water droplets further removes the tiny dust in the air.

[0027] The filter comprises a primary filter layer 20, an activated carbon filter layer 21, a HEPA filter layer 22, and an antibacterial filter layer. The primary filter layer 20, the activated carbon filter layer 21, the HEPA filter layer 22, and the antibacterial filter layer are sequentially arranged on the side of the filter plate 5 and fixedly connected to the filter plate 5.

[0028] When the outside air enters the filter box 16 through the air inlet and passes through the filter plate 5, it first passes through the primary filter layer 20. The primary filter layer 20 is mainly used to remove larger particles in the air, such as dust, hair, etc. The air after the primary filtration then enters the activated carbon filter layer 21. Activated carbon has a very high adsorption capacity and can remove harmful gases and odors in the air, such as organic compounds such as formaldehyde and benzene. Next, the air enters the HEPA (high-efficiency particulate air) filter layer. The HEPA filter layer 22 can capture particles with a diameter of more than 0.3 microns, including tiny pollutants such as viruses, bacteria, and pollen. Finally, the air passes through the antibacterial filter layer. The antibacterial filter layer 23 uses special materials or technologies to inhibit or kill bacteria and other microorganisms passing through its surface. By combining the primary filter layer 20, the activated carbon filter layer 21, the HEPA filter layer 22, and the antibacterial filter layer, the indoor air can be fully and efficiently purified to provide users with a healthy and fresh indoor environment.

[0029] The opening cover 8 is movably connected to the filter box 16 via a hinge.

[0030] The cover 8 is movably connected to the filter box 16 by a hinge. This connection allows the cover 8 to be turned over relative to the filter box 16, thereby facilitating the user to open and close.

[0031] The primary filter layer 20 is made of a metal mesh or synthetic fibers.

[0032] Metal mesh is strong, durable and easy to clean. Metal mesh is used to intercept larger particles, such as dust, hair, etc. Its mesh size can be adjusted as needed to achieve different filtering effects. Synthetic fiber is made of polymer, which is light, soft and easy to process. It can effectively remove larger particles in the air.

[0033] Working principle: When the user turns on the air purification device, the controller 2 starts the drive motor 9. The output end of the drive motor 9 drives the fan 10 to start rotating, forming an airflow. External air enters the filter box 16 through the air inlet 1. The airflow first passes through the filter plate 5, which filters the dust in the air. When the external air enters the filter box 16 through the air inlet and passes through the filter plate 5, it first passes through the primary filter layer 20. The primary filter layer 20 is mainly used to remove larger particles in the air, such as dust, hair, etc. The air after the primary filtration then enters the activated carbon filter layer 21. Activated carbon has a very high adsorption capacity and can remove harmful gases and odors in the air, such as organic compounds such as formaldehyde and benzene. Next, the air enters the HEPA (high-efficiency particulate air) filter layer. The HEPA filter layer 22 can capture particles with a diameter of more than 0.3 microns, including tiny pollutants such as viruses, bacteria, and pollen. Finally, the air passes through the antibacterial filter layer. The antibacterial filter layer 23 uses special materials or technologies to inhibit or kill bacteria and other microorganisms passing through its surface. By combining the primary filter layer 20, the activated carbon filter layer 21, the HEPA filter layer 22, and the antibacterial filter layer, the indoor air can be fully and efficiently purified to provide users with a healthy and fresh indoor environment. As the filter plate 5 is continuously used, the dust on it will gradually increase, causing the airflow through the filter plate 5 to gradually weaken. Due to the obstruction of the airflow, the pressure difference on both sides of the filter plate 5 will change. The pressure on the side of the filter plate 5 close to the pressure sensor 4 will gradually decrease, and the pressure on the side of the filter plate 5 close to the air inlet 1 will be higher than the pressure on the side of the filter plate 5 close to the pressure sensor 4. The high pressure will push the filter plate 5 to slide along the slide rail 3 to the side close to the pressure sensor 4 and compress the spring 6. The elastically deformed spring 6 squeezes the pressure sensor 4 at the other end of the spring 6. The pressure sensor 4 senses the pressure change and converts the change into an electrical signal, and then sends these signals to the controller 2. After the controller 2 receives the signal from the pressure sensor 4, the controller 2 transmits the instruction to the communication module 7. After receiving the instruction from the controller 2, the communication module 7 will send a notification of cleaning or replacing the filter plate 5 to the user's mobile device through the network. After receiving the notification, the user opens the cover 8 to replace the filter plate 5. The cover 8 and the filter box 16 are movably connected by a hinge. This connection method allows the cover 8 to be flipped relative to the filter box 16, which is convenient for the user to open and close. After the air passes through the filter plate 5, it continues to flow to the purification component. At this time, the air has been preliminarily filtered and most of the larger dust has been removed. Next, the air that has passed through the filter plate 5 enters the purification box 11 through the channel connecting the filter box 16 and the purification box 11. Due to the previous filtering process, most of the larger dust has been removed from the air at this time. Inside the purification box 11, the water source enters the spray column 12 through the water inlet pipe 14 and sprays downward from the top of the spray column 12.In this process, the spray water contacts the passing air, and the gravity of the water droplets further removes the tiny dust in the air. When the water droplets combine with the dust in the air, the formed sewage is discharged through the leaking hole 15, thereby keeping the inside of the purification box 11 clean. The air after spray purification continues to flow and is discharged through the air outlet 17, and the purified air flows back into the room. Through the spray purification method, the tiny dust and harmful gases in the air can be effectively removed, providing users with a healthier and fresher indoor environment. The four supporting feet 18 provide stable support for the purification box 11. After the air purification is completed, it flows back to the outside. The combination of the pressure sensor 4 and the spring 6 realizes the real-time monitoring of the state of the filter plate 5. And the communication module 7 promptly notifies the user to clean or replace it, thereby ensuring that the air purification equipment works continuously and efficiently. The opening cover 8 cooperates with the filter plate 5 means that after the user receives the notification, the opening cover 8 is opened to replace the filter plate 5. The metal grid has the characteristics of being strong, durable and easy to clean. The metal grid is used to intercept larger particles, such as dust, hair, etc. The mesh size can be adjusted as needed to achieve different filtering effects. Synthetic fibers are made of polymers and are light, soft and easy to process. They can effectively remove larger particles from the air.
