Description
Technical Field
[0001] The present application relates to the technical field of air purification equipment, and specifically to an air purification device that is convenient for replacing filter elements. Background Art
[0002] Air purification refers to providing overall solutions for various indoor environmental problems, such as sterilization, dust reduction and haze removal, removal of harmful decoration residues and odors, etc., to improve living and working conditions and enhance physical and mental health. Indoor environmental pollutants and pollution sources mainly include radioactive gases, mold, particulate matter, decoration residues and secondhand smoke.
[0003] An existing patent (publication number: CN218583370U) discloses an air purification device for convenient filter element replacement, including an air purification box, one end of which is provided with two air inlet grooves, the inner wall of which is fixedly connected to a filter fan, the other end of which is provided with an air outlet groove, the inner wall of which is fixedly connected to an exhaust filter screen, one side of the air purification box is provided with a replacement groove, and the inner wall of which is slidably connected to a filter element plate.
[0004] The above-mentioned comparative document points out that, by setting a push-on self-locking component in cooperation with the bottom edge of the filter element plate, the device can pop out the filter element plate from the replacement slot only by the operator pressing the part of the filter element plate exposed outside the air purification box. At the same time, during the installation of the filter element plate, the filter element plate is inserted into the replacement slot, and the push-on self-locking component is used again to make the fixing and replacement process of the filter element plate more convenient, thereby increasing the practicality of the equipment and reducing the labor intensity of the operator. However, although the process of replacing the filter element is simplified in this device, if the push-on self-locking component fails or is damaged, it may require professional repair or replacement, which may increase maintenance costs and even reduce the sealing between the replacement slot and the filter element plate, which may cause air leakage and affect the air purification effect.

[0014] Furthermore, a protective net is fixedly connected to a side of the housing away from the baffle.
[0015] Through the above solution, the main function of the protective net is to prevent external objects or personnel from contacting the moving parts inside the housing, thereby avoiding possible injuries or damages and increasing the safety of the equipment.
[0016] Furthermore, a handle is fixedly connected to the upper end of the shell.
[0017] Through the above solution, the handle is used to lift the device for easy movement.

[0023] The air purification device is convenient for replacing the filter element. Through the arrangement of the threaded column, the pressure plate and the baffle plate, the filter element plate is arranged inside the baffle plate by sliding. The structure of the threaded column and the pressure plate makes it easy to replace the filter element plate. When the filter element needs to be replaced, it is only necessary to rotate the threaded column to loosen the fixing of the pressure plate on the filter element plate, and then the filter element plate can be slid out from the inside of the baffle plate.

[0033] See also Figure 1 , Figure 3 and Figure 5 A sealing strip 18 is fixedly connected to the side of the filter plate 9 away from the threaded column 5. The sealing strip 18 is used to increase the airtightness between the filter plate 9 and the baffle 2. The filter plate 9 is slidably arranged inside the baffle 2. A dustproof net 7 is fixedly connected to the inside of the pressure plate 6. The dustproof net 7 can block large particles of dust and impurities in the air and prevent them from directly contacting the filter plate 9. This reduces the clogging and pollution of the filter plate 9 and extends the service life of the filter. A handle 8 is fixedly connected to the end of the threaded column 5 away from the pressure plate 6, and a handle 11 is fixedly connected to the upper end of the baffle rod 10. The handle 8 is designed to facilitate the rotation of the threaded rod, and the handle 11 is designed to facilitate pulling out the filter plate 9.
[0034] See also Figure 3 , Figure 4 and Figure 5A partition 12 is fixedly connected to the inside of the shell 1, and two air outlet pipes 13 are fixedly connected to the inside of the partition 12. A bracket 14 is fixedly connected to the inside of the two air outlet pipes 13. A fan 15 is fixedly connected to the inside of the two brackets 14. The fan 15 is fixed to the inside of the air outlet pipe 13 through the bracket 14 to draw air into the shell 1 and blow it out after filtering. A protective net 16 is fixedly connected to the side of the shell 1 away from the baffle 2.

Two legs 19 are fixedly connected to the bottom ends of the shell 1 and the baffle 2. The legs 19 are used to support the device. The pressure plate 6 is slidably arranged inside the baffle 2, and the pressure plate 6 can be moved inside the baffle 2 by rotating the threaded column 5.
[0035] In the present embodiment, an air purification device that is convenient for replacing the filter element is provided. Through the arrangement of the threaded column 5, the pressure plate 6, and the baffle 2, the filter element plate 9 is slidably arranged inside the baffle 2. The structure of the threaded column 5 and the pressure plate 6 makes it easy to replace the filter element plate 9. When the filter element needs to be replaced, it is only necessary to rotate the threaded column 5 to loosen the fixation of the pressure plate 6 to the filter element plate 9, and then the filter element plate 9 can be slid out from the inside of the baffle 2. When installing a new filter element plate 9, it is only necessary to slide it into the inside of the baffle 2 and then rotate the threaded column 5 to fix the pressure plate 6. This design reduces the time and labor intensity of replacing the filter element. The side of the filter element plate 9 away from the threaded column 5 is fixedly connected with a sealing strip 18, which ensures that the filter element plate 9 can maintain good sealing when sliding inside the baffle 2, prevents air leakage, and improves the air purification effect.
[0036] It should be noted that when installing the filter element plate 9, the threaded column 5 is rotated by the handle 8 so that the pressing plate 6 presses the filter plate tightly against one side of the baffle 2, and the sealing strip 18 is squeezed to increase the sealing performance of the filter element plate 9 during installation.
[0037] The working principle of the above embodiment is:
[0038] First, the user places the air purification device in the environment that needs to be purified. After the device is started, the fan 15 starts to work inside the air outlet 13 through the bracket 14, and the external air is drawn into the housing 1. When the air passes through the filter core plate 9, large particles of dust and impurities are blocked by the dustproof net 7, and the clean air is further filtered through the filter core plate 9, and then blown out through the air outlet 13, providing the user with a clean breathing environment. With the use of the filter core plate 9, dust and impurities will gradually accumulate, resulting in a decrease in the filtering effect. When the filter core needs to be replaced, the user turns The handle 8 is used to rotate the threaded column 5 and loosen the fixation on the pressure plate 6. Then, the baffle rod 10 and the filter plate 9 are pulled out from the inside of the baffle 2 by the handle 11, so that the user can easily take out the old filter plate 9 from the inside of the baffle 2. After preparing the new filter plate 9, the user slides it into the inside of the baffle 2 and rotates the handle 8 so that the threaded column 5 drives the pressure plate 6 to press the new filter plate 9 tightly against one side of the baffle 2. The sealing performance of the filter plate 9 during installation is further increased by squeezing the sealing strip 18. After installing the new filter plate 9, the fan 15 is continued to be started for air purification. The new filter plate 9 will continue to filter dust and impurities in the air and provide users with continuous clean air.
