Description

Technical Field

[0001] This utility model relates to the field of air purification equipment technology, specifically to an air purification device. Background Technology

[0002] Currently, oil fume air purification equipment is widely used in production and daily life. Its working principle is to draw oil fumes into the oil fume removal equipment through the air intake device, and then carbonize and adsorb the oil fumes through the adsorption device in the removal equipment to obtain clean air. The impeller of the air intake device draws air into its interior and discharges it from the exhaust port.

[0003] For example, Chinese Patent No. CN218846354U discloses an air purification device, including a storage box, a liquid filling pipe, a liquid filling port, a time display screen, a fixing frame, a support, a connector, a connecting frame, a rotary motor, a rotary shaft, a guide fan, a fixing component, a filter, an extraction pump, and an extraction port. It effectively solves the defects of most traditional air purification devices on the market, which are simple in function and rudimentary in structure. While ensuring basic purification effect, it can also use air freshener to clean the air, further improving the practicality of the entire device. It is an excellent air purification device.

[0004] However, the aforementioned air purification devices are inconvenient to replace the filter element, and the direction of the exhaust fresh air cannot be adjusted, which reduces the applicability of the device. Utility Model Content

[0005] The purpose of this invention is to provide an air purification device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An air purification device includes: a mounting frame, a connecting seat fixedly mounted inside the mounting frame, a dual-axis motor fixedly mounted on the upper surface of the connecting seat, impellers fixedly mounted on the outer surfaces of the output shafts on both sides of the dual-axis motor, the impellers being rotatably mounted inside a retaining cylinder, the retaining cylinder being fixedly mounted on both sides inside the mounting frame, an exhaust pipe being connected to the outer surface of the retaining cylinder, the other end of the exhaust pipe being connected to a filter mechanism, and the filter mechanism being fixedly mounted on the upper surface of the mounting frame.

[0008] Preferably, air intake ports are provided on both sides of the mounting frame. The air intake ports are connected to the surrounding cylinder, so that the impeller can rotate inside the surrounding cylinder to draw air into the surrounding cylinder and discharge it into the filtration mechanism through the exhaust pipe for purification.

[0009] Preferably, the filtration mechanism includes a bottom cylinder, two sets of connecting columns are fixedly installed on the upper surface of the bottom cylinder, connecting rings are fixedly installed on the upper outer surfaces of the two sets of connecting columns, a retaining ring is rotatably installed between the bottom cylinder and the connecting rings, and an exhaust port is installed on the outer surface of the retaining ring.

[0010] Preferably, the lower surface of the bottom cylinder is connected to the exhaust pipe, and an air filter element is inserted between the two sets of connecting columns inside the bottom cylinder. The inner ring of the air filter element is equal in diameter to and connected to the exhaust pipe.

[0011] Preferably, a U-shaped frame is fixedly installed on the upper surface of the bottom cylinder, and a threaded rod is fixedly installed on the upper surface of the U-shaped frame. The U-shaped frame and the threaded rod can be fitted into the inner ring of the air filter element. A top cover can be inserted into the connecting ring, so that the top cover can be snapped onto the upper surface of the air filter element and pass through the connecting post and the threaded rod, and the connecting post and the threaded rod can slide out from the upper surface of the top cover.

[0012] Preferably, the outer surface of the threaded rod is threaded with a wing bolt, which allows the wing bolt to press against the upper surface of the top cover, thereby giving the top cover sufficient pressure to press against the upper surface of the air filter element. This ensures that the air entering the bottom cylinder can only be blown out from the inner ring of the air filter element to the outer ring and discharged to the outside through the exhaust port connected to the outer surface of the ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Through the design of the enclosure, dual-shaft motor, impeller, exhaust pipe, and filtration mechanism, during use, the dual-shaft motor is started to drive the impeller to rotate inside the enclosure. This rotation of the impeller, driven by the dual-shaft motor, draws air into the enclosure through the intake port and discharges it into the filtration mechanism through the exhaust pipe for filtration and purification. Furthermore, the purified air discharged from the filtration mechanism can be adjusted by the operator by rotating the exhaust port to regulate the direction of the filtered airflow. This flexibility allows for adjustments to the airflow direction based on actual needs, such as different room layouts and personnel distribution, to achieve optimal purification effect and comfort, thereby improving user satisfaction and user experience.

[0015] 2. Through the design of the bottom cylinder, shroud, connecting ring, air filter element, threaded rod, wing bolt, and top cover, when air is discharged into the exhaust pipe, the exhaust pipe guides the air into the bottom cylinder. The air entering the bottom cylinder is located in the inner ring of the air filter element, and then the air is discharged through the air filter element to the outer surface of the air filter element between the shroud and the outer ring. This design allows the air to fully contact the filter material of the filter element when passing through the filter element, thereby improving the filtration efficiency and effectively removing impurities and pollutants from the air. The filtered air is then discharged to the outside through the exhaust port installed on the outer surface of the shroud. The filtered impurities are retained on the inner ring wall of the air filter element, and the shroud can drive the exhaust port to rotate between the bottom cylinder and the connecting ring. This allows the operator to rotate the exhaust port according to actual needs, thereby adjusting the direction of the purified air and improving the flexibility and applicability of the air purification device.

[0016] When the air filter needs to be replaced, the operator simply unscrews the wing bolt from the outer surface of the threaded rod to release the pressure on the top cover, allowing the operator to remove the top cover from the connecting ring and remove the air filter for replacement. This design simplifies the filter replacement process, making maintenance more convenient and reducing maintenance costs and time. The top cover can then be slid back into the connecting ring, and the wing bolt threaded onto the outer surface of the threaded rod. This allows the wing bolt to press against the upper surface of the top cover, providing sufficient pressure to press against the upper surface of the air filter. This ensures that the air entering the bottom cylinder can only be filtered through the air filter, thus guaranteeing the stability and reliability of the filtration effect.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 This embodiment provides an air purification device, including: a mounting frame 1, a connecting seat 103 fixedly installed inside the mounting frame 1, a dual-axis motor 104 fixedly installed on the upper surface of the connecting seat 103, impellers 105 fixedly installed on the outer surfaces of the output shafts on both sides of the dual-axis motor 104, the impellers 105 being rotatably installed inside a retaining cylinder 102, the retaining cylinder 102 being fixedly installed on both sides inside the mounting frame 1, an exhaust pipe 106 being connected to the outer surface of the retaining cylinder 102, the other end of the exhaust pipe 106 being connected to a filter mechanism 2, and the filter mechanism 2 being fixedly installed on the upper surface of the mounting frame 1.

[0025] The mounting frame 1 has air intake ports 101 on both sides. The air intake ports 101 are connected to the surrounding cylinder 102, so that the impeller 105 can rotate inside the surrounding cylinder 102 to draw air into the surrounding cylinder 102 through the air intake ports 101 and discharge it into the filter mechanism 2 through the exhaust pipe 106 for purification.

[0026] Through the design of the enclosure 102, dual-axis motor 104, impeller 105, exhaust pipe 106, and filter mechanism 2, during use, the dual-axis motor 104 is started to drive the impeller 105 to rotate inside the enclosure 102. This rotation of the impeller 105 within the enclosure 102 causes the air intake 101 to draw air into the enclosure 102 and discharge it through the exhaust pipe 106 into the filter mechanism 2 for filtration and purification. Furthermore, when the purified air is discharged from the filter mechanism 2, the operator can rotate the exhaust port 204 to adjust the direction of the filtered airflow. This flexibility allows for adjustments to the airflow direction based on actual needs, such as different room layouts and personnel distribution, to achieve optimal purification effect and comfort, thereby improving user satisfaction and experience.

[0027] like Figures 4-5As shown, the filter mechanism 2 includes a bottom cylinder 201. Two sets of connecting columns 202 are fixedly installed on the upper surface of the bottom cylinder 201. Connecting rings 210 are fixedly installed on the upper outer surfaces of the two sets of connecting columns 202. A retaining ring 203 is rotatably installed between the bottom cylinder 201 and the connecting ring 210. An exhaust port 204 is connected to the outer surface of the retaining ring 203.

[0028] The lower surface of the bottom cylinder 201 is connected to the exhaust pipe 106. An air filter element 205 is inserted between the two sets of connecting columns 202 inside the bottom cylinder 201. The inner ring of the air filter element 205 is equal in diameter to and connected to the exhaust pipe 106.

[0029] The bottom cylinder 201 has a U-shaped frame 206 fixedly installed on its upper inner surface, and a threaded rod 207 fixedly installed on its upper surface. The U-shaped frame 206 and the threaded rod 207 can be fitted into the inner ring of the air filter element 205. A top cover 208 can be inserted into the connecting ring 210, so that the top cover 208 can be snapped onto the upper surface of the air filter element 205 and pass through the connecting post 202 and the threaded rod 207, and the connecting post 202 and the threaded rod 207 can slide out from the upper surface of the top cover 208.

[0030] The outer surface of the threaded rod 207 is threaded with a wing bolt 209, which allows the wing bolt 209 to press against the upper surface of the top cover 208. This allows the top cover 208 to have sufficient pressure to press against the upper surface of the air filter element 205, so that the air entering the bottom cylinder 201 can only be blown out from the inner ring of the air filter element 205 to the outer ring and discharged to the outside through the exhaust port 204 connected to the outer surface of the circumferential ring 203.

[0031] Through the design of the bottom cylinder 201, the retaining ring 203, the connecting ring 210, the air filter element 205, the threaded rod 207, the wing bolt 209, and the top cover 208, when air is discharged into the exhaust pipe 106, the exhaust pipe 106 can guide the air into the bottom cylinder 201. The air entering the bottom cylinder 201 will be located at the inner ring of the air filter element 205, thus allowing the air to be discharged through the air filter element 205 to the space between the outer surface of the air filter element 205 and the retaining ring 203. This design ensures that the air can fully contact the filter material of the filter element when passing through it. This improves filtration efficiency, effectively removes impurities and pollutants from the air, and allows the filtered air to be discharged to the outside through the exhaust port 204 connected to the outer surface of the retaining ring 203. The filtered impurities remain on the inner ring wall of the air filter element 205. The retaining ring 203 can drive the exhaust port 204 to rotate between the bottom cylinder 201 and the connecting ring 210, allowing the staff to rotate the exhaust port 204 according to actual needs, thereby adjusting the direction of the purified air and improving the flexibility and applicability of the air purification device.

[0032] When the air filter element 205 needs to be replaced, the operator only needs to unscrew the wing bolt 209 from the outer surface of the threaded rod 207 to release the pressure on the top cover 208, allowing the operator to remove the top cover 208 from the connecting ring 210 and remove the air filter element 205 for replacement. This design simplifies the filter element replacement process, making maintenance more convenient and reducing maintenance costs and time. Subsequently, the top cover 208 can be slid back into the connecting ring 210, and the wing bolt 209 can be threaded onto the outer surface of the threaded rod 207, allowing the wing bolt 209 to press against the upper surface of the top cover 208. This ensures that the top cover 208 has sufficient pressure to press against the upper surface of the air filter element 205, so that the air entering the bottom cylinder 201 can only be filtered through the air filter element 205, thus ensuring the stability and reliability of the filtration effect.

[0033] Based on the above technical solution, the working steps of this solution are summarized as follows: During use, the dual-shaft motor 104 drives the impeller 105 to rotate within the casing 102. This rotation of the impeller 105 within the casing 102 causes the intake port 101 to draw air into the casing 102 and discharge it through the exhaust pipe 106 into the bottom casing 201. The air entering the bottom casing 201 is located within the inner ring of the air filter element 205, allowing it to pass through the air filter element 205 and exit between its outer surface and the casing ring 203. The filtered air is then discharged to the outside through the exhaust port 204 connected to the outer surface of the casing ring 203. Filtered impurities remain on the inner ring wall of the air filter element 205. When the air filter element 205 needs to be replaced, the operator only needs to unscrew the wing bolt 209 from the outer surface of the threaded rod 207 to release the pressure on the top cover 208, allowing the operator to remove the top cover 208 from the connecting ring 210 and remove the air filter element 205 for replacement. Then, the top cover 208 can be slid back into the connecting ring 210, and the wing bolt 209 can be threaded onto the outer surface of the threaded rod 207, so that the wing bolt 209 can press against the upper surface of the top cover 208. This allows the top cover 208 to have sufficient pressure against the upper surface of the air filter element 205, ensuring that the air entering the bottom cylinder 201 can only be filtered through the air filter element 205, thus guaranteeing the stability and reliability of the filtration effect.

[0034] In summary, this device allows for convenient replacement of the air filter 205. When the filtered air is discharged from the exhaust port 204, the surrounding ring 203 can drive the exhaust port 204 to rotate between the bottom cylinder 201 and the connecting ring 210. This allows operators to rotate the exhaust port 204 according to actual needs, thereby adjusting the direction of the purified air and improving the flexibility and applicability of the air purification device.
