[0069] Two second sliding grooves 20 are opened in the baffle 10 and communicate with the first sliding groove 9. Two inserting rods 21 are respectively slidably connected in the two second sliding grooves 20, and one end of each of the two inserting rods 21 extends to the inner wall of the first sliding groove 9 and is inserted and matched with the first sliding groove 9. The other end of the inserting rod 21 is fixedly connected to a spring 22 fixed to the inner wall of the second sliding groove 20. Two pressing grooves 23 are respectively formed on the two inserting rods 21;

[0070] A fourth sliding groove 24 is opened in the baffle 10 and communicates with the two second sliding grooves 20. A pressing block 25 is slidably connected in the fourth sliding groove 24, and both ends of the pressing block 25 respectively extend into the two pressing grooves 23. A pressing block 26 is fixedly connected to the pressing block 25, and one end of the pressing block 26 penetrates through the inner wall of the fourth sliding groove 24 and extends to the outside and is slidably connected to the baffle 10.

[0071] Among them, when the user needs to slide the baffle 10, the user presses the two pressing blocks 26 with hands, so that the pressing block 26 drives the pressing block 25 to slide in the fourth sliding groove 24, so that the pressing block 25 presses the two pressing grooves 23, so that one end of each of the two inserting rods 21 enters the two second sliding grooves 20 from the inner wall of the first sliding groove 9 respectively, and the two springs 22 are respectively compressed. At this time, the fixation of the baffle 10 is released. Subsequently, the user slides the baffle 10 with hands, so that the baffle 10 slides in the first sliding groove 9. When the user needs to fix the baffle 10 in the first sliding groove 9, the user releases the hand pressing the pressing block 26, so that one end of each of the two inserting rods 21 is respectively affected by the rebounding force of the two springs 22 and is respectively inserted into the inner wall of the first sliding groove 9 to fix the baffle 10 in the first sliding groove 9, ensuring that external dust cannot enter the second through groove 5 and preventing the filter element 8 placed in the slot 7 from being contaminated by external dust and affecting the filtering effect.

[0072] Embodiment 7:

[0073] This embodiment provides an air purifier that facilitates filter element replacement. In addition to including the technical solutions of the above embodiment, it also has the following technical features. Both ends of the pressing block 25 are inserted and matched with the two pressing grooves 23 respectively.

[0074] Among them, it is ensured that both ends of the pressing block 25 can be respectively inserted into the two pressing grooves 23.

[0075] In use, the user presses two pressing blocks 26 with hands, causing the pressing blocks 26 to drive the extrusion block 25 to slide in the fourth chute 24, so that the extrusion block 25 extrudes two extrusion grooves 23, enabling one ends of two insertion rods 21 to enter two second chutes 20 respectively from the inner wall of the first chute 9 and compressing two springs 22 respectively. At this time, the fixation of the baffle 10 is released. Subsequently, the user slides the baffle 10 with hands, causing the baffle 10 to slide in the first chute 9. When the two baffles 10 slide to appropriate positions, the inner cavities of the two second through grooves 5 will be exposed to the outside. Subsequently, the user inserts a new filter element 8 into one of the slots 7 through one of the second through grooves 5 with hands. Then, the user starts the motor 19, causing the output shaft of the motor 19 to drive one of the third sprockets 16 to rotate in the second movable groove 15, so that one of the third sprockets 16 drives the other third sprocket 16 to rotate through the second chain 17. When the two third sprockets 16 rotate, the two third sprockets 16 will respectively drive two second sprockets 13 to rotate in two first movable grooves 11, causing the two second sprockets 13 to drive two first sprockets 12 to rotate in the two first movable grooves 11 respectively through two first chains 14. When the two first sprockets 12 rotate, the two first sprockets 12 will respectively drive two threaded rods 3 to rotate in the first through groove 2, causing the sliding chamber 6 to move between the two second through grooves 5 and the first through groove 2 under the action of the threads of the two threaded rods 3. When the sliding chamber 6 moves to an appropriate position, the sliding chamber 6 will drive the old filter element 8 into the other second through groove 5. At the same time, the sliding chamber 6 will drive the new filter element 8 to enter the inner cavity of the air purifier body 1 from one of the second through grooves 5 for use. Subsequently, the user pulls out the old filter element 8 from the other slot 7 with hands, ensuring that the user can quickly replace the filter element 8. Then, a new filter element 8 is inserted into the other slot 7 again for the next replacement. Subsequently, the user slides the two baffles 10 reversely with hands, causing the two baffles 10 to slide along the two first chutes 9 respectively. When the two baffles 10 move reversely to appropriate positions, the user releases the hands pressing the two pressing blocks 26, enabling one ends of the multiple insertion rods 21 to be respectively inserted into the inner walls of the two first chutes 9 under the action of the rebounding forces of the multiple springs 22, fixing the two baffles 10 in the two first chutes 9 respectively, ensuring that external dust cannot enter the two second through grooves 5 and preventing the filter element 8 placed in the slot 7 from being contaminated by external dust and affecting the filtering effect.

[0076] The embodiments of the present application have been described above in conjunction with the accompanying drawings. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
