[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figure 1 - Figure 6 As shown, an air purifier facilitating the disassembly and assembly of a filter screen includes a purifier body 1 and a cover plate 2. The cover plate 2 is slidably connected to the outside of the purifier body 1. A cylindrical filter screen 3 is installed inside the purifier body 1. A first device slot 4 and a second device slot 5 are opened inside the purifier body 1. It further includes:

[0024] A fixed block 6 is arranged inside the purifier body 1 and is located directly below the cylindrical filter screen 3. A pair of fixed plates 7 are arranged inside the first device slot 4. Both of the pair of fixed plates 7 are fixedly connected to the outside of the fixed block 6. A first limiting rod 8 is slidably connected to the inside of both of the pair of fixed plates 7. Both ends of the first limiting rod 8 are fixedly connected to the inner wall of the first device slot 4. The bottom end of the fixed block 6 is fixedly connected to an inclined block 9. A baffle 10 is arranged inside the second device slot 5. The baffle 10 is in contact with the inclined block 9. A sliding mechanism for supporting the movement of the baffle 10 is arranged on the periphery of the baffle 10.

[0025] The chute 11 is opened at the bottom end of the inner wall of the second device slot 5. A slide bar 12 is slidably connected inside the chute 11. A connecting plate 13 and a connecting rod 23 are fixedly connected to the outer side of the slide bar 12 respectively. A spring 14 is fixedly connected to one side of the connecting plate 13. The end of the spring 14 away from the connecting plate 13 is fixedly connected to the inner wall of the second device slot 5. The end of the connecting rod 23 away from the slide bar 12 is in contact with one end of the cover plate 2 close to the purifier body 1. A driving mechanism for driving the baffle 10 to move is arranged around the slide bar 12.

[0026] There are many inconveniences in the cleaning and replacement of the filter screen of traditional air purifiers. For example, when disassembling and assembling, it is necessary to first open the cover plate 2 on the side of the purifier, then loosen the fixing parts for fixing the filter screen, and then the filter screen can be removed. This requires two steps, namely removing the cover plate 2 and loosening the fixing parts, which to a certain extent affects the use experience and popularity of the air purifier. In the use of this practical embodiment, when the cylindrical filter screen 3 needs to be removed, in the initial state, the cover plate 2 is pressing on the connecting rod 23, and the fixing block 6 is pressing on the bottom end of the cylindrical filter screen 3 to ensure that the cylindrical filter screen 3 cannot shake, and the spring 14 is in a deformed state. When the cover plate 2 is opened, the spring 14 releases elastic potential energy and pushes the connecting plate 13 to move in the direction of the cover plate 2. The movement of the connecting plate 13 will drive the slide bar 12 to move along the inside of the chute 11. The movement of the slide bar 12 drives the driving mechanism to operate. The operation of the driving mechanism will drive the baffle 10 to move along the sliding mechanism. When the baffle 10 moves past the inclined block 9, the extrusion of the baffle 10 on the inclined block 9 ends. Under the action of gravity, the inclined block 9 and the fixing block 6 will move downwards. As the fixing block 6 moves downwards, the cylindrical filter screen 3 will move downwards under the action of gravity. At this time, the extrusion and fixation of the fixing block 6 on the cylindrical filter screen 3 end, and the cylindrical filter screen 3 can be quickly removed. Through the above structural design, the original two steps are simplified into one step. Only by opening the cover plate 2, the extrusion and fixation of the fixing block 6 on the cylindrical filter screen 3 will end together, improving the work efficiency and reflecting the practicality of the device. When the cylindrical filter screen 3 needs to be installed, only need to place the cylindrical filter screen 3 on the surface of the fixing block 6 and push the cover plate 2 to be clamped on the outside of the purifier body 1. During the process of pushing the cover plate 2, the cover plate 2 will press on the connecting rod 23. The force on the connecting rod 23 will drive the connecting plate 13 to press the spring 14 through the slide bar 12. And during the movement of the slide bar 12, the slide bar 12 will drive the baffle 10 to move through the driving extrusion. The baffle 10 presses the inclined surface of the inclined block 9, and the inclined surface of the inclined block 9 is stressed and will move upwards along the outside of the first limiting rod 8 through the fixing plate 7. The upward movement of the inclined block 9 will drive the fixing block 6 to move upwards to press the cylindrical filter screen 3, thereby playing a role in fixing the cylindrical filter screen 3. When the cover plate 2 is clamped on the outside of the purifier body 1 ends, the fixing block 6 just presses the cylindrical filter screen 3 until it cannot move.

[0027] Such as Figure 3 AndFigure 4 As shown, the sliding mechanism includes two pairs of second limiting rods 15 and two pairs of limiting blocks 16. The two pairs of second limiting rods 15 are respectively slidably connected inside the two pairs of limiting blocks 16. The two pairs of limiting blocks 16 are both fixedly connected to one end of the baffle 10 away from the inclined block 9. Both ends of the two pairs of limiting blocks 16 are fixedly connected to the inner wall of the second device groove 5.

[0028] When the baffle 10 moves, the baffle 10 will drive the two pairs of limiting blocks 16 to move synchronously. During the movement of the limiting blocks 16, restricted by the second limiting rods 15, the limiting blocks 16 can only move along the outside of the second limiting rods 15, thereby playing a limiting role in the movement of the baffle 10, avoiding the movement deviation of the baffle 10, and improving the stability of the device.

[0029] As Figure 4 、 Figure 5 and Figure 6 shown, the driving mechanism includes a first rack, a first spur gear 17, a transmission rod 18, a second spur gear 19 and a second rack 20. The first rack is fixedly connected to the side of the slide bar 12 away from the connecting plate 13. The first spur gear 17 meshes with the first rack. The first spur gear 17 is fixedly connected to the outside of the transmission rod 18. The two ends of the transmission rod 18 are respectively rotatably connected to the top and bottom of the inner wall of the second device groove 5. The second spur gear 19 is fixedly connected to the outside of the transmission rod 18 and is located at the top of the first spur gear 17. The second rack 20 is fixedly connected to the outside of the baffle 10. The second rack 20 meshes with the second spur gear 19.

[0030] When the slide bar 12 moves inside the chute 11, the slide bar 12 will drive the first rack to move synchronously. Since the first rack and the first spur gear 17 are in a meshing state, the first rack will drive the first spur gear 17 to rotate. The first spur gear 17 then drives the second spur gear 19 to rotate through the transmission rod 18. At this time, the rotation of the second spur gear 19 drives the second rack 20 to move away from the baffle 10. The movement of the second rack 20 further drives the baffle 10 to move. When the baffle 10 moves and contacts and presses the inclined surface of the inclined block 9, the inclined block 9 will move upward under the force. Finally, the baffle 10 will block the downward reset route of the inclined block 9, as Figure 4 shown, thereby quickly performing the function of squeezing and fixing the cylindrical filter screen 3.

[0031] As Figure 2 and Figure 4 shown, a first magnetic attraction block 21 is fixedly connected to the side of the cover plate 2 close to the purifier body 1. One end of the first magnetic attraction block 21 away from the cover plate 2 adsorbs a second magnetic attraction block. The second magnetic attraction block is fixedly connected to the outside of the purifier body 1.

[0032] Since the cover plate 2 is slidably connected to the purifier body 1 only by friction, it is prone to instability and falling off. When this practical embodiment is in use, a first magnetic attraction block 21 and a second magnetic attraction block are installed on the side of the cover plate 2 close to the purifier body 1, so that the first magnetic attraction block 21 and the second magnetic attraction block are attracted to each other, thereby strengthening the connection between the cover plate 2 and the purifier body 1 and avoiding the situation that the cover plate 2 is prone to falling off.

[0033] As Figure 3 and Figure 4 shown, a friction pad 22 is fixedly connected to the top of the fixing block 6, and the friction pad 22 is made of rubber.

[0034] Installing the friction pad 22 on the top of the fixing block 6 can prevent the friction caused by the direct contact between the cylindrical filter screen 3 and the fixing block 6. At the same time, the setting of the friction pad 22 can also extrude the cylindrical filter screen 3 by the fixing block 6, playing a certain buffering role.

[0035] Working principle: Traditional air purifiers have many inconveniences in filter cleaning and replacement. For example, when disassembling and assembling, it is necessary to first open the cover plate 2 on the side of the purifier, then loosen the fixing parts that fix the filter, and then the filter can be removed. This requires two steps, namely removing the cover plate 2 and loosening the fixing parts, which to a certain extent affects the use experience and popularity of the air purifier. In the use of this practical embodiment, when the cylindrical filter 3 needs to be removed, in the initial state, the cover plate 2 presses against the connecting rod 23, and the fixing block 6 presses against the bottom end of the cylindrical filter 3 to ensure that the cylindrical filter 3 cannot shake, and the spring 14 is in a deformed state. When the cover plate 2 is opened, the spring 14 releases elastic potential energy and pushes the connecting plate 13 in the direction of the cover plate 2. The movement of the connecting plate 13 will drive the slide bar 12 to move along the inside of the chute 11. The movement of the slide bar 12 drives the driving mechanism to operate. The operation of the driving mechanism will drive the baffle 10 to move along the sliding mechanism. When the baffle 10 moves past the inclined block 9, the extrusion of the baffle 10 on the inclined block 9 ends. Under the action of gravity, the inclined block 9 and the fixing block 6 will move downward. As the fixing block 6 moves downward, the cylindrical filter 3 will move downward under the action of gravity. At this time, the extrusion and fixation of the fixing block 6 on the cylindrical filter 3 end, and the cylindrical filter 3 can be quickly removed. Through the above structural design, the original two steps are simplified into one step. Only by opening the cover plate 2, the extrusion and fixation of the fixing block 6 on the cylindrical filter 3 will end together, improving work efficiency and reflecting the practicality of the device. When the cylindrical filter 3 needs to be installed, only need to place the cylindrical filter 3 on the surface of the fixing block 6 and push the cover plate 2 to be clamped on the outside of the purifier body 1. During the process of pushing the cover plate 2, the cover plate 2 will press against the connecting rod 23. The connecting rod 23 will drive the connecting plate 13 to press the spring 14 through the slide bar 12. And during the movement of the slide bar 12, the slide bar 12 will drive the baffle 10 to move through driving extrusion. The baffle 10 presses the inclined surface of the inclined block 9, and the inclined surface of the inclined block 9 will move upward along the outside of the first limiting rod 8 through the fixing plate 7. The upward movement of the inclined block 9 will drive the fixing block 6 to move upward to press the cylindrical filter 3, thereby playing a role in fixing the cylindrical filter 3. When the cover plate 2 is clamped on the outside of the purifier body 1, the fixing block 6 just presses the cylindrical filter 3 until it cannot move;

[0036] When the baffle 10 moves, the baffle 10 will drive two pairs of limiting blocks 16 to move synchronously. During the movement of the limiting blocks 16, they are limited by the second limiting rod 15, so that the limiting blocks 16 can only move along the outside of the second limiting rod 15, thus playing a limiting role in the movement of the baffle 10, avoiding the deviation of the movement of the baffle 10 and improving the stability of the device;

[0037] When the slider 12 moves inside the chute 11, the slider 12 will drive the first rack to move synchronously. Since the first rack is in meshing engagement with the first spur gear 17, the first rack will drive the first spur gear 17 to rotate. The first spur gear 17 then drives the second spur gear 19 to rotate through the transmission rod 18. At this time, the rotation of the second spur gear 19 drives the second rack 20 to move away from the baffle 10. The movement of the second rack 20 then drives the baffle 10 to move. When the baffle 10 moves to contact and press the inclined surface of the inclined block 9, the inclined block 9 will move upward under the force. Eventually, the baffle 10 will block the downward reset route of the inclined block 9, as Figure 4 shown, thus quickly performing the function of squeezing and fixing the cylindrical filter screen 3;

[0038] Since the cover plate 2 is slidably connected to the purifier body 1 only by friction, it is prone to instability and detachment. In the practical embodiment of the present invention, when in use, a first magnetic attraction block 21 and a second magnetic attraction block are installed on the side of the cover plate 2 and the purifier body 1 that are close to each other, so that the first magnetic attraction block 21 and the second magnetic attraction block are attracted to each other, thereby strengthening the connection between the cover plate 2 and the purifier body 1 and avoiding the situation that the cover plate 2 is easily detached;

[0039] A friction pad 22 is installed at the top of the fixing block 6, which can prevent the friction caused by the direct contact between the cylindrical filter screen 3 and the fixing block 6. At the same time, the setting of the friction pad 22 can also press the cylindrical filter screen 3 by the fixing block 6, playing a certain buffering role.

[0040] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claimed rights.
