[0002] The disinfection chamber is a closed device integrating air filtration and ultraviolet sterilization functions, mainly used for efficient purification of air or object surfaces and inactivation of pathogens. Its core functions include: multi-layer filtration: removing particulate matter and microorganisms through physical interception; ultraviolet sterilization: using ultraviolet lamps to destroy the DNA / RNA of microorganisms, achieving secondary sterilization; and closed-loop circulation: ensuring no pollutant leakage during the treatment process, improving safety and efficiency.
[0003] Traditional disinfection chamber filter installation methods have significant drawbacks, especially in scenarios with frequent replacements (such as hospitals, laboratories, and high-dust factories). Most designs rely on bolt fixing or snap-fit connections, requiring tools (such as screwdrivers) or multiple people to work together. This process is time-consuming and can easily damage the filter structure. To address these issues, we offer a detachable multi-layer air filtration and UV-assisted disinfection chamber structure. Utility Model Content
[0004] The purpose of this invention is to provide a detachable multi-layer air filtration and ultraviolet synergistic disinfection chamber structure. Through the cooperation of the installation components and locking components, it solves the problem that the disinfection chambers in the prior art rely on bolt fixing or snap-fit hard connection, which requires tools or multiple people to cooperate, is time-consuming to operate and is prone to damage to the filter structure.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.
[0006] This utility model relates to a detachable multi-layer air filtration and ultraviolet synergistic disinfection chamber structure, including a disinfection chamber. A filter box is fixedly connected to the top of the disinfection chamber, and a door is provided on the front side of the disinfection chamber. An installation assembly is provided inside the filter box. The installation assembly includes a fixed frame fixedly connected inside the filter box, a filter screen placed inside the fixed frame, a fixed block fixedly connected to one side of the filter screen, a rotating rod movably connected to the fixed frame via a bearing, and a fixed plate fixedly connected to one side of the rotating rod. A locking assembly is provided inside the fixed frame. The locking assembly includes a toothed plate disposed inside the fixed frame, teeth meshing on the surface of the toothed plate, a locking plate fixedly connected to one side of the toothed plate, and a magnetic holding electromagnet fixedly connected to one side of the fixed frame.
[0007] The present invention is further configured such that a limiting groove adapted to the filter screen is provided on the side of the fixed frame near the fixed plate, and a first spring is fixedly connected inside the limiting groove.
[0008] The present invention is further configured such that a fixing groove adapted to the fixing plate is provided inside the fixing block, and the rotating rod and the fixing plate are arranged as a group on one side of the fixing frame.
[0009] The present invention is further configured such that the teeth are fixedly connected to the surface of the rotating rod, and the top and bottom of the fixing frame are provided with push grooves, and the tooth plate and the rotating rod are both located inside the push grooves.
[0010] The present invention is further configured such that a movable groove is provided inside the toothed plate, and a limiting slide plate is slidably connected inside the movable groove.
[0011] The present invention is further configured such that a locking groove is provided on one side of the fixed frame, the magnetic holding electromagnet is fixedly connected in the locking groove, and a second spring is fixedly connected inside the locking groove.
[0012] The present invention is further configured such that the locking plate is made of magnetic material, and a door is provided on one side of the filter box, with the locking plate located on the side of the door.
[0013] The present invention has the following beneficial effects.
[0014] 1. This utility model significantly optimizes the filter replacement process through the modular installation component design. During operation, simply push the filter in and push the locking plate. The spring preload and the fixing plate automatically lock to ensure a tight fit of the filter. When unlocking, the locking plate is released by instantaneous current.

It is especially suitable for high-frequency maintenance scenarios such as hospitals and laboratories, reducing downtime and lowering labor costs.
[0015] 2. This utility model utilizes a magnetically retaining electromagnet and a magnetically conductive locking plate, consuming only a small amount of electrical energy when switching states. After engagement, it relies on a permanent magnet to maintain the lock, achieving zero standby power consumption. Compared to traditional continuously powered electromagnetic locks, it saves more than 90% of energy. At the same time, the limiting slide groove and toothed transmission ensure precise movement of the toothed plate, avoiding mechanical jamming caused by deviation. Spring reset and double locking effectively prevent the filter from loosening, enhancing sealing and vibration resistance. This design not only reduces energy consumption and the risk of overheating but also extends the service life of the filter and locking mechanism, making it suitable for harsh environments such as industrial cleanrooms.

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0025] Example 1
[0026] Please see Figures 1-5This utility model is a detachable multi-layer air filtration and ultraviolet synergistic disinfection chamber structure, including a disinfection chamber 1, a filter box 2 fixedly connected to the top of the disinfection chamber 1, a door 3 provided on the front side of the disinfection chamber 1, and an installation assembly inside the filter box 2. The installation assembly includes a fixed frame 4 fixedly connected inside the filter box 2, a filter screen 5 placed inside the fixed frame 4, a fixed block 6 fixedly connected to one side of the filter screen 5, a rotating rod 7 movably connected to the fixed frame 4 via a bearing, and a fixed plate 8 fixedly connected to one side of the rotating rod 7. The installation components enable quick installation and removal of the filter screen 5 without tools or complex operations. The fixing frame 4 contains a locking assembly, including a toothed plate 9 inside the frame, teeth 10 meshing with the surface of the toothed plate 9, a locking plate 11 fixedly connected to one side of the toothed plate 9, and a magnetic holding electromagnet 12 fixedly connected to one side of the fixing frame 4. The working principle of the magnetic holding electromagnet 12 is as follows: when a positive pulse current is applied to the coil, the electromagnetic force and the permanent magnet's magnetic circuit are superimposed, driving the armature to attract and lock. At this time, the permanent magnet's magnetic force dominates, maintaining the attracted state without continuous power supply. When a reverse pulse current is applied to the coil, the electromagnetic force cancels the permanent magnet's magnetic circuit, the armature disengages, and the filter screen detaches, returning to the released state. Similarly, no power supply is needed after release. The magnetic holding electromagnet 12, through the mechanism of "electromagnetic drive + permanent magnet locking," can both initiate a continuous magnetic attraction state and achieve zero-power retention. The locking assembly ensures the filter screen 5 is fixed after installation, preventing loosening due to vibration or airflow impact during operation.
[0027] Example 2
[0028] Please see Figures 1-5Based on embodiment 1, the fixed frame 4 has a limiting groove 13 adapted to the filter screen 5 on the side near the fixed plate 8. A first spring 14 is fixedly connected inside the limiting groove 13. The limiting groove 13 is used to limit the placement of the filter screen 5. The first spring 14 is used to compress the filter screen 5 during installation. The compressed first spring 14 generates a pushing force on the filter screen 5, pushing the filter screen 5 towards the fixed plate 8. Combined with the locking effect of the fixed plate 8 and the fixed block 6, the fixing effect of the filter screen 5 is improved. The fixed block 6 has a fixing groove adapted to the fixed plate 8. The rotating rod 7 and the fixed plate 8 are arranged as a group on one side of the fixed frame 4. The fixing groove allows the fixed plate 8 to enter the fixed block 6 and lock the filter screen 5. The teeth 10 are fixedly connected to the surface of the rotating rod 7. The top and bottom of the fixed frame 4 have pushing grooves. The teeth 9 and the rotating rod 7 are located inside the pushing grooves. The teeth 9 and the teeth 10 are fixedly connected to the rotating rod 7. The toothed plate 9 is configured to drive the rotating rod 7 to rotate. A movable slide groove 15 is provided inside the toothed plate 9, and a limiting slide plate 16 is slidably connected inside the movable slide groove 15. The limiting slide plate 16 is fixedly connected inside the pushing groove. Through the movable slide groove 15 and the limiting slide plate 16, the toothed plate 9 is limited during movement to prevent it from shifting. A locking groove is provided on one side of the fixed frame 4, and a magnetic holding electromagnet 12 is fixedly connected in the locking groove. A second spring is fixedly connected inside the locking groove. 17. With the setting of the second spring 17, when the filter screen 5 needs to be replaced, the magnetic holding electromagnet 12 loses its magnetic attraction. The compressed second spring 17 pushes the locking plate 11 out of the locking groove under the reset action, making it convenient for personnel to pull the locking plate 11. The locking plate 11 is made of magnetic material. The filter box 2 is provided with a door on one side. The locking plate 11 is located on the side of the door. With the locking plate 11 made of magnetic material, the magnetic holding electromagnet 12 can magnetically attract the locking plate 11 and fix the locking plate 11.
[0029] The working principle of this utility model is as follows: When the filter screen 5 needs to be replaced, the magnetic holding electromagnet 12 in the corresponding fixed frame 4 is energized, so that the magnetic holding electromagnet 12 returns to the released state. At this time, the locking plate 11 loses its magnetic attraction and fixing force. The second spring 17 pushes the locking plate 11 out of the locking groove in the reset action. At this time, the person pulls the locking plate 11 outward. The locking plate 11 drives the toothed plate 9 to move. The toothed plate 9 drives the rotating rod 7 to rotate under the action of the teeth 10. The rotating rod 7 drives the fixed plate 8 to rotate, so that the fixed plate 8 is separated from the fixing groove of the fixed block 6. After the limiting effect of the fixed plate 8 is lost, the first spring 14 resets and pushes the filter screen 5 out of the limiting groove 13. At this time, the filter screen 5 can be taken out.
[0030] After placing the new filter screen 5 inside the limiting groove 13, push the locking plate 11 to move into the locking groove. The locking plate 11 drives the toothed plate 9 to reset. At this time, the toothed plate 9 drives the rotating rod 7 to reverse, and the rotating rod 7 drives the fixing plate 8 to reverse, so that the fixing plate 8 rotates into the fixing groove of the fixing block 6. Then, energize the magnetic holding electromagnet 12 again, and the magnetic holding electromagnet 12 magnetically attracts the locking plate 11. At this time, the filter screen 5 is replaced.
[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
