[0001] This utility model relates to the field of high-efficiency filter technology, specifically to a high-efficiency purification filter containing a nanofiber composite filter layer. Background Technology

[0002] High-efficiency particulate air (HEPA) filters can filter out fine particles and are commonly used in places with high air quality requirements, such as operating rooms and electronics workshops.

[0003] Existing filters typically have embedded filter layers, which can become clogged over time, affecting filtration efficiency. Furthermore, ordinary filters cannot provide efficient filtration. Therefore, a high-efficiency purification filter containing a nanofiber composite filter layer is needed. Summary of the Invention

[0004] To address this issue, this utility model provides a high-efficiency purification filter containing a nanofiber composite filter layer. When the user needs to disassemble or install the filter screen, the user starts the servo motor, causing the winding wheel to rotate, which in turn drives the steel rope to retract, thereby adjusting the two filter frames so that the filter frames can extend, making it convenient for the user to replace the filter screen. This solves the problem that existing filters generally have embedded filter layers inside, which can cause the filter screen to become clogged over time, thus affecting the filtration effect. At the same time, ordinary filter screens cannot achieve a high-efficiency filtration effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency purification filter containing a nanofiber composite filter layer, comprising a filter body, an air inlet pipe at the top of the filter body, a positioning frame embedded inside the air inlet pipe, two filter frames embedded inside the positioning frame, and the filter frames sliding with the positioning frame;

[0006] Both filter frames are equipped with filter screens, which are composite filter layers containing nanofibers, and positioning plates are fixedly connected to the outside of the filter screens.

[0007] The mounting mechanism is located on the outside of the air intake pipe and is used to disassemble and replace the filter frame.

[0008] Preferably, the top of the filter frame is provided with a plurality of positioning bolts, which are used to position and install the positioning plate and the filter screen.

[0009] Preferably, the installation mechanism includes multiple round rods, which are respectively fixedly connected to the outside of two filter frames. Two movable frames are provided on the outside of the air intake pipe, and the two movable frames are respectively fixedly connected to the outer ends of the multiple round rods.

[0010] Preferably, the mounting mechanism further includes a servo motor, which is located at the rear of the air intake pipe. A mounting bracket is fixedly connected to the rear of the air intake pipe, and the mounting bracket is fixed to the front of the servo motor.

[0011] Preferably, a drive shaft is embedded inside the mounting bracket. The drive shaft is connected to the output end of the servo motor. One end of the drive shaft passes through the rear side of the air intake pipe and is movably connected to the mounting bracket and the air intake pipe through a rolling bearing.

[0012] Preferably, a connecting bracket is provided on the front side of the air intake pipe, and the connecting bracket is located at the bottom of the mounting bracket.

[0013] Preferably, a transmission rod is embedded inside the connecting frame, and the rear end of the transmission rod extends to the outside of the rear side of the air intake pipe. The transmission rod is movably connected to the air intake pipe and the connecting frame through a rolling bearing.

[0014] Preferably, a first sprocket and a second sprocket are fixedly sleeved on the outer sides of the drive shaft and the drive rod, respectively. A chain is sleeved on the outer sides of the first sprocket and the second sprocket, and the first sprocket and the second smelting furnace are connected by the chain drive.

[0015] Preferably, two winding wheels are provided on the rear side of the air intake pipe, and steel ropes are wound around the outer sides of the two winding wheels.

[0016] Preferably, a positioning rod is fixedly connected to the front side of each of the two connecting frames, and a positioning wheel is sleeved on the outer side of each of the two positioning rods, with the steel rope wrapped around the outer side of the two positioning wheels.

[0017] The beneficial effects of this utility model are:

[0018] When the user needs to disassemble or install the filter, the user starts the servo motor, causing the winding wheel to rotate and the steel rope to retract. This adjusts the two filter frames, allowing them to extend and facilitating filter replacement. This addresses the problem that existing filters typically have embedded filter layers, which can become clogged over time, affecting filtration efficiency. Furthermore, ordinary filter screens often lack high-efficiency filtration. This invention facilitates filter replacement for users, greatly simplifying the process. Additionally, the device uses a composite filter layer containing nanofibers, resulting in superior filtration and significantly improving filter efficiency. Attached Figure Description

[0026] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0027] See attached document Figure 1 -Appendix Figure 4 The present invention provides a high-efficiency purification filter containing a nanofiber composite filter layer, comprising a filter body 1, an air inlet pipe 2 at the top of the filter body 1, a positioning frame 3 embedded inside the air inlet pipe 2, and two filter frames 4 embedded inside the positioning frame 3, the filter frames 4 sliding with the positioning frame 3.

[0028] Both filter frames 4 are equipped with filter screens 5. The filter screens 5 are composite filter layers containing nanofibers, and positioning plates are fixedly connected to the outside of the filter screens 5.

[0029] The mounting mechanism is located on the outside of the air intake pipe 2 and is used to disassemble and replace the filter frame 4.

[0030] In this embodiment, when the user needs to disassemble and install the filter screen 5, the user starts the servo motor 9 to make the winding wheel 16 rotate, thereby driving the steel rope 17 to retract, thereby adjusting the two filter frames 4 so that the filter frames 4 can extend, making it convenient for the user to replace the filter screen.

[0031] To achieve the purpose of structural installation, this device adopts the following technical solution: Multiple positioning bolts 6 are embedded at the top of the filter frame 4, which position and install the positioning plates and filter screen 5. The installation mechanism includes multiple round rods 7, which are fixedly connected to the outer sides of the two filter frames 4. Two movable frames 8 are provided on the outer side of the air inlet pipe 2, and are fixedly connected to the outer ends of the multiple round rods 7. The installation mechanism also includes a servo motor 9, which is located at the rear of the air inlet pipe 2. A mounting frame 10 is fixedly connected to the rear of the air inlet pipe 2 and is fixed to the front of the servo motor 9. A drive shaft 11 is embedded inside the mounting frame 10 and is connected to the output end of the servo motor 9. One end of the drive shaft 11 passes through the rear of the air inlet pipe 2 and is movably connected to the mounting frame 10 and the air inlet pipe 2 through a rolling bearing. A connecting frame 12 is provided at the front of the air inlet pipe 2. At the bottom of the frame 10, a transmission rod 13 is embedded inside the connecting frame 12. The rear end of the transmission rod 13 extends to the outside of the rear side of the air inlet pipe 2. The transmission rod 13 is movably connected to the air inlet pipe 2 and the connecting frame 12 through rolling bearings. The transmission shaft 11 and the transmission rod 13 are respectively fixedly sleeved with a first sprocket 14 and a second sprocket 15. A chain is sleeved on the outside of the first sprocket 14 and the second sprocket 15. The first sprocket 14 and the second smelting furnace are connected by a chain drive. Two winding wheels 16 are provided on the rear side of the air inlet pipe 2. Steel rope 17 is wound on the outside of the two winding wheels 16.

[0032] The servo motor 9 drives the drive shaft 11 and the first sprocket 14 to rotate. The rotation of the first sprocket 14 drives the second sprocket 15 and the drive rod 13 to rotate. The rotation of the drive shaft 11 and the drive rod 13 drives the two winding wheels 16 to rotate. The rotation of the two winding wheels 16 drives the two steel ropes 17 to retract, thereby driving the two positioning wheels 18 and the positioning rod to move. This causes the two moving frames 8 to move outward to both sides, so that the filter frame 4 can extend outward, making it convenient for the user to replace and install the filter screen 5. Similarly, when the servo motor 9 controls the drive shaft 11 to reverse, the steel rope 17 relaxes, causing the spring 20 to rebound, so that the filter frame 4 is embedded into the positioning frame 3, achieving the effect of positioning and installation.

[0033] The usage process of this utility model is as follows: When the user needs to disassemble and install the filter screen 5, the user starts the servo motor 9, causing the winding wheel 16 to rotate, thereby driving the steel rope 17 to retract, thus adjusting the two filter frames 4 so that the filter frames 4 extend, making it convenient for the user to replace the filter screen. The servo motor 9 drives the transmission shaft 11 and the first sprocket 14 to rotate. The rotation of the first sprocket 14 drives the second sprocket 15 and the transmission rod 13 to rotate. The rotation of the transmission shaft 11 and the transmission rod 13 drives the two winding wheels 16 to rotate. The rotation of the two winding wheels 16 drives the two steel ropes 17 to retract, thereby driving the two positioning wheels 18 and the positioning rod to move, causing the two moving frames 8 to move outward to both sides, thus allowing the filter frames 4 to extend, making it convenient for the user to replace and install the filter screen 5. Similarly, when the servo motor 9 controls the transmission shaft 11 to reverse, the steel rope 17 relaxes, causing the spring 20 to rebound, thus allowing the filter frame 4 to be embedded inside the positioning frame 3, achieving the effect of positioning and installation.
