[0018] Please see Figures 1-5 This utility model provides a technical solution: an air purifier with an easy-to-replace filter element, comprising an air purifier body 1. Multiple air inlets 2 are provided on the surface of the air purifier body 1. The outer casing 3 is installed on top of the air purifier body 1; The maintenance mechanism 4 is located on one side of the air purifier body 1; The quick disassembly and assembly mechanism 5 is located on one side of the maintenance mechanism 4; Filter element 6 is located on one side of quick-release mechanism 5; The clamping and mounting mechanism 7 is located inside the housing 3; The quick-assembly / disassembly mechanism 5 includes two first fixed frames 501, with a bidirectional lead screw 502 installed between them. One end of the bidirectional lead screw 502 movably passes through a single first fixed frame 501 and is connected to a worm gear 503. A worm 504 is meshed with the outer side of the worm gear 503, and an operating handwheel 505 is connected to one end of the worm 504. Two sliding frames 506 are provided on the outer side of the bidirectional lead screw 502, and a connecting frame 507 is rotatably connected to both ends of each sliding frame 506. Two second fixed frames 5 are installed on one side of the maintenance mechanism 4. 08. Two first fixing rods 509 are installed between the two second fixing brackets 508. Two first clamping brackets 510 are rotatably installed on the outer side of each first fixing rod 509. One end of each connecting bracket 507 is rotatably connected to a corresponding first clamping bracket 510. Through the setting of the quick disassembly and assembly mechanism 5, the filter element can be clamped and fixed, and installed into the air purifier as the maintenance mechanism 4 opens and closes. This greatly reduces the difficulty of installing and disassembling the filter element, simplifies the replacement operation process, optimizes the user experience, and meets the actual use needs.

[0019] like Figure 3 and Figure 5As shown, the clamping and mounting mechanism 7 includes a mounting plate 701, which is located on the inner bottom of the housing 3. Two brackets 702 are symmetrically arranged at both ends of the top of the mounting plate 701. A guide rod 703 is installed between each pair of brackets 702. Two first springs 704 are sleeved on the outer side of each guide rod 703. Two second clamping frames 705 are slidably installed on the outer side of the two guide rods 703. A pull ring 706 is installed on one side of each second clamping frame 705. An exhaust fan 707 is arranged between the two second clamping frames 705. A guide duct 708 is installed at the bottom of the mounting plate 701. By setting up the clamping and mounting mechanism 7, the exhaust fan can be clamped and fixed, thereby reducing the difficulty of its installation and disassembly, facilitating its maintenance and replacement, greatly saving labor and time costs, and further optimizing the user experience.

[0020] like Figure 1 , Figure 3 and Figure 4 As shown, the maintenance mechanism 4 includes a door 401. Two hinges 403 are installed at the bottom of the door 401. The two hinges 403 are bolted to one side of the air purifier body 1. Two knobs 402 are installed at the top of the door 401. With the maintenance mechanism 4, the air purifier body 1 can be quickly opened for inspection, effectively reducing the difficulty of operation. At the same time, it is linked with the quick disassembly mechanism 5 to realize the quick replacement of the filter element 6.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, both ends of the mounting plate 701 are provided with adjustment limit mechanisms 8; The adjusting limit mechanism 8 includes two handles 801, which are fixedly installed at both ends of the mounting plate 701. Second fixing rods 802 are installed on both sides of the outer shell 3. A second spring 803 is sleeved on the outer side of each second fixing rod 802. A buckle 804 is slidably installed on the outer side of each second fixing rod 802. By adjusting the setting of the limiting mechanism 8, the height of the exhaust fan 707 and the air guide duct 708 can be flexibly adjusted, thereby effectively reducing the difficulty of operation. At the same time, it is linked with the clamping and mounting mechanism 7, further reducing the maintenance difficulty of the exhaust fan 707 and greatly saving the later maintenance cost.

[0022] like Figure 1 , Figure 2 and Figure 3As shown, a mounting bracket 9 is provided on the top inner side of the outer casing 3, and an air outlet cover 10 is installed on the top of the mounting bracket 9. Countersunk bolts 11 are installed at the four corners of the top of the air outlet cover 10. A negative ion generator 12 is installed on one side of the inner side of the outer casing 3. Through the arrangement of the mounting bracket 9, the air outlet cover 10, the countersunk bolts 11 and the negative ion generator 12, the purified air can be quickly discharged into the room or work area, while the top is protected to prevent external factors from damaging the inside of the device.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, a support base 13 is installed on the inner bottom of the air purifier body 1, and an anti-slip base 14 is installed on the bottom of the air purifier body 1. The support base 13 and the anti-slip base 14 can provide stable support for the filter element 6 and prevent polluted air from entering the filter element 6 from the bottom, thereby improving the quality of air purification. At the same time, the anti-slip base 14 provides stable support for the air purifier body 1 and increases the friction with the ground to prevent the device from sliding or shifting during use.

[0024] The usage and working principle of this device are as follows: First, place the device in the designated location and connect it to a power source to provide a stable power supply and ensure normal operation. The exhaust fan 707 draws outside air into the air purifier body 1 through the air inlet 2. The filter element 6 filters dust and harmful substances from the air, and the purified air is then discharged outwards through the exhaust fan 707 from the air outlet cover 10. Next, when the filter element 6 needs to be replaced, disconnect the power to the device and simultaneously pull both handles 801 upwards. This causes the mounting plate 701 to slide upwards along the air guide tube 708. Simultaneously, the handles 801 press against the latch 804, overcoming the elasticity of the second spring 803, and slide on the second fixed rod 802. When the handles 801 reach their highest position, the second spring 803 rebounds and pushes the latch 804 to lock the handles 801. At this point, turning the two knobs 402 contacts the door 4. In the locked state of 01, tighten the groove and pull the door 401, causing the hinge 403 to rotate and the door 401 to slowly open. Then, turn the operating handwheel 505, causing the worm gear 504 to drive the worm wheel 503 and the double-acting screw 502 to rotate, causing the sliding frame 506 to slide on the double-acting screw 502, and pulling the first clamping frame 510 connected by the connecting frame 507 to rotate and open, releasing the clamp on the filter element 6, so that the new filter element 6 can be replaced. After replacement, the above process is reversed to reinstall the replaced filter element 6. Finally, when the exhaust fan 707 needs to be inspected and replaced, turn the countersunk bolt 11 to remove the exhaust cover 10, and then pull the two pull rings 706 at the same time, so that the second clamping frame 705 overcomes the elastic force of the first spring 704 and slides on the guide rod 703, releasing the clamp on the exhaust fan 707, so that the exhaust fan 707 can be removed for inspection and replacement.

[0025] By following the steps outlined above, you can easily use an air purifier with a replaceable filter.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
