[0004] However, the existing purification devices have a relatively simple structure, mainly relying on filters on both sides to filter the airflow. After long-term use, the filters will be clogged with dust, and the filters connected by threaded components affect the ease of disassembly and maintenance.

[0005] Therefore, it is necessary to redesign and modify air purification devices that are easy to maintain. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide an air purification device that is easy to maintain, with the advantages of easy disassembly and cleaning. This solves the problem that the existing purification devices have a relatively simple structure, mainly relying on filters on both sides to filter the airflow, and that the filters become clogged with dust after long-term use, and the filters connected by threaded components affect the ease of disassembly and maintenance.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an air purification device that is easy to maintain, comprising a body;

[0008] Filter assemblies are located on both sides of the machine body;

[0009] The four corners of the left and right sides of the machine body are movably connected to swing arms via pins. The side of the swing arm away from the machine body extends to the outside of the filter assembly. The inner side of the swing arm is movably connected to a pressure plate via a pin. The inner side of the pressure plate contacts the surface of the filter assembly. A transmission structure is provided on the left side of the machine body. The transmission structure can control multiple swing arms to swing in opposite directions.

[0010] As a preferred embodiment of this utility model, the transmission structure includes a connecting frame fixedly connected to the left side of the machine body. A bidirectional screw is movably connected inside the connecting frame via a bearing. Both sides of the surface of the bidirectional screw are threaded with a threaded sleeve. Both ends of the right side of the threaded sleeve are fixedly connected with a push rod. The side of the push rod away from the threaded sleeve extends into the interior of the swing rod. The swing rod and the push rod are slidably connected.

[0011] As a preferred embodiment of this utility model, a fan is provided on the top of the machine body, and the bottom of the fan extends into the interior of the machine body and is plugged into the machine body.

[0012] As a preferred embodiment of this utility model, movable blocks are fixedly connected to the top of both the left and right sides of the machine body. The surface of the movable blocks is movably connected to a pawl via a pin, and the side of the pawl away from the movable block extends to the top of the exhaust fan.

[0013] In a preferred embodiment of this invention, a force-bearing plate is fixedly connected to the side of the claw near the movable block, and a pressing rod is fixedly connected to both sides of the top of the upper screw sleeve, with the top of the pressing rod contacting the bottom of the force-bearing plate.

[0014] In a preferred embodiment of this invention, the surface of the extrusion rod is movably connected to a roller via a pin, and the outer surface of the roller contacts the bottom of the force-bearing plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model can release the clamping force of the filter screen components on both sides of the machine body at the same time by using the swing rod linkage pressure plate, avoiding the tedious operation of disassembling each one of the traditional threaded connections. The transmission structure drives the four corner swing rods to swing in opposite directions, ensuring that the filter screen components are subjected to uniform force and avoiding filter screen deformation or loosening caused by single-point fixing.

[0017] 2. The bidirectional screw of this utility model drives the two screw sleeves on both sides to move in opposite directions through the thread, so as to realize the linear push and pull of the push rod on the swing rod, control the swing angle of the swing rod stably and reliably, and the thread transmission has a self-locking characteristic, which can prevent the filter screen from loosening due to vibration or airflow impact after it is fixed.

[0018] 3. This utility model uses a plug-in installation method for the exhaust fan, which is convenient for individual disassembly, cleaning or replacement without the need to disassemble the entire machine. The bottom of the exhaust fan extends into the inside of the machine and directly guides the airflow through the filter assembly, reducing wind resistance and improving purification efficiency.

[0019] 4. This utility model forms a mechanical engagement between the claw and the top of the exhaust fan, and the plug-in structure enhances the installation stability of the exhaust fan. The claw is hinged by a movable block, and can be released from the exhaust fan synchronously with the movement of the transmission structure when unlocking, realizing one-click synchronous maintenance of the filter and the fan.

[0020] 5. When the screw sleeve moves, the squeezing rod pushes the force plate, driving the pawl to rotate around the pin shaft, thus realizing the synchronous operation of unlocking the filter screen and unlocking the exhaust fan. Users only need to operate the transmission structure to release the filter screen and exhaust fan at the same time, avoiding the complexity of multi-step disassembly.

[0021] 6. This utility model converts sliding friction into rolling friction through rollers, reducing wear between the extrusion rod and the force plate, extending service life. The rollers also reduce resistance when the extrusion rod pushes against the force plate, improving the user's operating experience and preventing jamming. Attached Figure Description

[0027] 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.

[0028] like Figures 1 to 4 As shown, the present invention provides an easy-to-maintain air purification device, including a body 1;

[0029] Filter assemblies 2 are installed on both sides of the main body 1;

[0030] The four corners of the left and right sides of the body 1 are movably connected to the swing rods 3 by pins. The side of the swing rods 3 away from the body 1 extends to the outside of the filter assembly 2. The inner side of the swing rods 3 is movably connected to the pressure plate 4 by pins. The inner side of the pressure plate 4 contacts the surface of the filter assembly 2. A transmission structure 5 is provided on the left side of the body 1. The transmission structure 5 can control the multiple swing rods 3 to swing in opposite directions.

[0031] refer to Figure 2 The transmission structure 5 includes a connecting frame 6 fixedly connected to the left side of the body 1. A bidirectional screw 7 is movably connected inside the connecting frame 6 via a bearing. Both sides of the surface of the bidirectional screw 7 are threadedly connected to a screw sleeve 8. Both ends of the right side of the screw sleeve 8 are fixedly connected to a push rod 9. The side of the push rod 9 away from the screw sleeve 8 extends into the interior of the swing rod 3. The swing rod 3 and the push rod 9 are slidably connected.

[0032] As a technical optimization of this utility model, the bidirectional screw 7 drives the two side sleeves 8 to move in opposite directions through the thread, so as to realize the linear push and pull of the push rod 9 on the swing rod 3, and control the swing angle of the swing rod 3 stably and reliably. The thread transmission has a self-locking characteristic, which can prevent the filter screen from loosening due to vibration or airflow impact after it is fixed.

[0033] refer to Figure 2 A fan 10 is provided on the top of the body 1, and the bottom of the fan 10 extends into the interior of the body 1 and is plugged into the body 1.

[0034] As a technical optimization of this utility model, the exhaust fan 10 is installed by plugging in, which makes it easy to disassemble, clean or replace it separately without disassembling the whole body 1. The bottom of the exhaust fan 10 extends into the inside of the body 1 and directly guides the airflow through the filter assembly 2, reducing wind resistance and improving purification efficiency.

[0035] refer to Figure 4 Movable blocks 11 are fixedly connected to the top of the left and right sides of the body 1. The surface of the movable blocks 11 is movably connected to the claws 12 by pins. The side of the claws 12 away from the movable blocks 11 extends to the top of the exhaust fan 10.

[0036] As a technical optimization of this utility model, the claw 12 forms a mechanical engagement with the top of the exhaust fan 10, and the plug-in structure enhances the installation stability of the exhaust fan 10. The claw 12 is hinged by the movable block 11, and can be released from the exhaust fan 10 synchronously with the action of the transmission structure 5 when unlocking, so as to realize one-click synchronous maintenance of the filter and the fan.

[0037] refer to Figure 4 A force-bearing plate 13 is fixedly connected to the side of the claw 12 near the movable block 11. Both sides of the top of the upper screw sleeve 8 are fixedly connected to the pressing rod 14, and the top of the pressing rod 14 contacts the bottom of the force-bearing plate 13.

[0038] As a technical optimization of this utility model, when the screw sleeve 8 moves, the pressing rod 14 pushes the force plate 13, driving the claw 12 to rotate around the pin shaft, realizing the synchronous operation of unlocking the filter screen and unlocking the exhaust fan 10. The user only needs to operate the transmission structure 5 to release the filter screen and exhaust fan 10 at the same time, avoiding the complexity of multi-step disassembly.

[0039] refer to Figure 4 The surface of the extrusion rod 14 is movably connected to a roller 15 via a pin, and the outer surface of the roller 15 contacts the bottom of the force plate 13.

[0040] As a technical optimization of this utility model, the roller 15 converts sliding friction into rolling friction, reduces wear between the extrusion rod 14 and the force plate 13, extends service life, and makes the resistance less when the extrusion rod 14 pushes the force plate 13, improves the user's operating experience, and avoids jamming.

[0041] The working principle and usage process of this utility model: The user rotates the bidirectional screw 7 on the left side of the machine body 1. According to the rotation direction, the bidirectional screw 7 drives the two side screw sleeves 8 to move towards each other. When the screw sleeves 8 move, the push rod 9 fixed on them slides accordingly. The push rod 9 is slidably connected to the swing rod 3, pushing the swing rod 3 to swing around the pin shafts at the four corners of the machine body 1. When the swing rod 3 swings inward, it drives the pressure plate 4 to disengage from the surface of the filter assembly 2, releasing the clamping pressure on the filter. After the pressure plate 4 is released, the filter assembly 2 can be easily pulled out from both sides of the machine body 1 for cleaning or replacement due to the loss of pressure. This process does not require traditional threaded disassembly, greatly improving maintenance efficiency. At the same time as the screw sleeve 8 moves, the top pressing rod 14 descends with the screw sleeve 8 and releases the bottom of the force plate 13 through the roller 15. After the force plate 13 is released from the force, the pawl 12 rotates around the pin shaft of the movable block 11, causing the pawl 12 to disengage from the top of the exhaust fan 10, releasing the fixation on the exhaust fan 10. The user can remove the filter assembly 2 and the exhaust fan 10 at the same time for comprehensive maintenance.

[0042] In summary, this easy-to-maintain air purification device, through the linkage of the swing arm 3 and the pressure plate 4, can simultaneously release the clamping force of the filter assemblies 2 on both sides of the body 1, avoiding the tedious operation of disassembling each one of the traditional threaded connections. The transmission structure 5 drives the four corner swing arms 3 to swing in opposite directions, ensuring that the filter assemblies 2 are subjected to uniform force, and avoiding filter deformation or loosening caused by single-point fixing.
