Description

Technical Field

[0001] This utility model relates to the field of air filter technology, and in particular to a sterilization device for air filters. Background Technology

[0002] An air filter is a device that uses porous filter materials to capture dust from a gas-solid two-phase flow and purify the gas. It purifies the air with low dust content and then delivers it into the room to ensure the process requirements of clean rooms and the air cleanliness of general air-conditioned rooms. It is generally used in clean workshops, clean factories, laboratories and clean rooms, or for dust prevention of electronic, mechanical and communication equipment, etc.

[0003] Patent CN221358999U discloses a sterilization device for an air filter, comprising a filter body. A first partition is fixedly installed inside the filter body near the air inlet, and a second partition is fixedly installed near the air outlet. A first filter plate is installed between the first partition and the inner wall of the filter body, and a second filter plate is installed between the second partition and the inner wall of the filter body. A third filter plate is installed between the first and second partitions. A first ultraviolet sterilization lamp is fixedly installed on the side of the first partition facing the second filter plate, and a second ultraviolet sterilization lamp is fixedly installed on the side of the second partition facing the first filter plate. This invention primarily filters air using three filter plates within the filter body, and then uses two ultraviolet sterilization lamps to irradiate the three filter plates, effectively killing bacteria and microorganisms on the filter plates, preventing their growth, extending the filter's lifespan, and protecting the environment.

[0004] However, the sterilization device for the air filter described above still has the following shortcomings:

[0005] The filter plates in the above device are distributed in a relatively scattered manner. Therefore, when replacing the filter element, it is necessary to go to each location to disassemble several filter plates one by one, which is time-consuming and labor-intensive. In view of this, we propose a sterilization device for air filters. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a sterilization device for air filters. This solves the technical problem that the current device has several filter plates that are relatively scattered, so when replacing the filter element, it is necessary to go to each location to disassemble several filter plates one by one, which is time-consuming and labor-intensive.

[0007] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a sterilization device for an air filter is designed and applied to the air filter body. A set of positioning plates are symmetrically fixed on the surface of the air filter body. A sterilization component is inserted into the air filter body. A set of limiting mechanisms are symmetrically provided on the surface of the sterilization component. A set of filter plates are symmetrically engaged on both sides inside the sterilization component.

[0008] The sterilization assembly includes a main support, which is engaged with the middle of the air filter body. A first auxiliary frame is attached to the right side of the main support, and a second auxiliary frame is attached to the left side of the main support. Several ultraviolet lamps are evenly distributed in a ring inside the main support. An inner groove is opened on the inner side of the top of the main support, and a gear is provided in the middle of the inner groove.

[0009] Preferably, the sterilization assembly further includes a support rod fixed to the top of the gear, and a set of toothed plates meshing with the surface of the gear.

[0010] Preferably, both the first auxiliary frame and the second auxiliary frame are provided with frustum-shaped flow channels inside, and the frustum-shaped flow channels inside the first auxiliary frame and the second auxiliary frame are symmetrically distributed, with the flow channel diameter being the largest on the side closer to the main support.

[0011] Preferably, a set of toothed plates are distributed in a 180-degree mirror image with respect to the gear axis, and the side of the toothed plate away from the gear always fits against the inner groove wall.

[0012] Preferably, the surfaces of the first auxiliary frame and the second auxiliary frame are respectively provided with slots that correspond horizontally to the protruding ends of a set of toothed plates.

[0013] Preferably, the limiting mechanism includes a fixed rod, which is fixed to the surface of the support rod. A spring is provided inside the fixed rod, and a T-shaped limiting rod is provided at one end of the spring near the opening of the fixed rod. A pull rod is fixedly connected to the surface of the T-shaped limiting rod, and a protective plate is fixedly connected to the surface of the pull rod.

[0014] Preferably, one end of the T-shaped limiting rod is inserted into the positioning plate, and the T-shaped limiting rod forms an elastic structure with the fixing rod through a spring.

[0015] Preferably, the surface of the fixed rod is provided with a groove for the pull rod to slide, and when the spring is in the normal state, the protective plate can completely cover the groove on the surface of the fixed rod.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model effectively connects the main support with the first auxiliary frame and the second auxiliary frame through a set of outwardly moving toothed plates. Subsequently, after the limitation mechanism is released, the upward movement of the main support can effectively drive the first auxiliary frame and the second auxiliary frame to move upward simultaneously, thereby removing a set of filter plates. This facilitates the quick replacement of a set of filter plates. When cleaning the ultraviolet lamp separately, after the limitation mechanism is released, the support rod is rotated, which causes the gear to drive a set of toothed plates to move inward. At this time, there is no connection between the main support and the first and second auxiliary frames, making it easy to remove the main support separately, which is quite convenient.

[0018] 2. In this utility model, a set of pull rods are moved toward the support rods, thereby effectively moving a set of T-shaped limiting rods away from a set of positioning plates, thus releasing the restriction of the positioning plates on the T-shaped limiting rods, facilitating the overall or partial upward movement of the sterilization assembly. When fixing the sterilization assembly, after moving a set of pull rods toward the support rods, the ends of the T-shaped limiting rods are aligned with the slots in the positioning plates. Then, the pull rods are released, and the ends of the T-shaped limiting rods pop out and effectively engage inside the positioning plates due to the spring's rebound force, thereby quickly achieving the limitation of the sterilization assembly.

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0029] A sterilization device for an air filter, see [link to documentation]. Figures 1 to 6 It is applied to the air filter body 1. A set of positioning plates 2 are symmetrically fixed on the surface of the air filter body 1. A sterilization component 3 is inserted into the air filter body 1. A set of limiting mechanisms 4 are symmetrically provided on the surface of the sterilization component 3. A set of filter plates 5 are symmetrically engaged on both sides inside the sterilization component 3.

[0030] The sterilization component 3 includes a main support 301, which is engaged with the middle of the air filter body 1. A first auxiliary frame 302 is attached to the right side of the main support 301, and a second auxiliary frame 303 is attached to the left side of the main support 301. Both the first auxiliary frame 302 and the second auxiliary frame 303 have frustum-shaped flow channels inside. The frustum-shaped flow channels inside the first auxiliary frame 302 and the second auxiliary frame 303 are symmetrically distributed, with the largest flow channel diameter on the side closest to the main support 301. Several ultraviolet lamps 304 are evenly distributed in a ring inside the main support 301. An inner groove 305 is provided on the inner side of the top, and a gear 306 is provided in the middle of the inner groove 305. The sterilization component 3 also includes a support rod 307, which is fixed to the top of the gear 306. A set of toothed plates 308 meshes with the surface of the gear 306. Furthermore, the set of toothed plates 308 are distributed in a 180-degree mirror image with the axis of the gear 306 as a reference. The side of the toothed plates 308 away from the gear 306 is always in contact with the wall of the inner groove 305. Furthermore, the surfaces of the first auxiliary frame 302 and the second auxiliary frame 303 are respectively provided with slots that correspond horizontally to the protruding ends of the set of toothed plates 308. This invention effectively connects the main support 301 with the first auxiliary frame 302 and the second auxiliary frame 303 through a set of outwardly moving toothed plates 308. Subsequently, after the limitation mechanism 4 is released, the upward movement of the main support 301 can effectively drive the first auxiliary frame 302 and the second auxiliary frame 303 to move upward simultaneously, thereby removing a set of filter plates 5 for quick replacement. When cleaning the ultraviolet lamp 304 separately, after the limitation mechanism 4 is released, the support rod 307 is rotated, causing the gear 306 to drive a set of toothed plates 308 to move inward. At this time, there is no connection between the main support 301 and the first auxiliary frame 302 and the second auxiliary frame 303, making it convenient to remove the main support 301 separately. Air flows from right to left. When passing through the flow channel of the first auxiliary frame 302, the air speed gradually decreases, which facilitates full contact with the ultraviolet lamp 304. Afterward, when the air passes through the flow channel of the second auxiliary frame 303, the air speed gradually increases.

[0031] It is worth noting that the limiting mechanism 4 includes a fixed rod 401, which is fixed to the surface of the support rod 307. A spring 402 is provided inside the fixed rod 401. A T-shaped limiting rod 403 is provided at one end of the spring 402 near the opening of the fixed rod 401. One end of the T-shaped limiting rod 403 is inserted into the positioning plate 2. The T-shaped limiting rod 403 and the fixed rod 401 form an elastic structure through the spring 402. A pull rod 404 is fixedly connected to the surface of the T-shaped limiting rod 403. A protective plate 405 is fixedly connected to the surface of the pull rod 404. Furthermore, a groove for the pull rod 404 to slide is opened on the surface of the fixed rod 401. When the spring 402 is in the normal state, the protective plate 405 can completely cover the groove opened on the surface of the fixed rod 401. In this invention, a set of pull rods 404 are moved toward the support rod 307, thereby effectively moving a set of T-shaped limiting rods 403 away from a set of positioning plates 2, thus releasing the restriction of the positioning plates 2 on the T-shaped limiting rods 403, facilitating the overall or partial upward movement of the sterilization component 3. When fixing the sterilization component 3, after moving a set of pull rods 404 toward the support rod 307, the end of the T-shaped limiting rod 403 is aligned with the slot of the positioning plate 2. Then, the pull rods 404 are released, and the end of the T-shaped limiting rod 403 pops out and effectively engages inside the positioning plate 2 due to the rebound force of the spring 402, thereby quickly achieving the limitation of the sterilization component 3.

[0032] Working principle: Air flows from right to left. A set of filter plates 5 improves the filtration effect. When the air passes through the first auxiliary frame 302, the air velocity gradually decreases, facilitating full contact with the ultraviolet lamp 304. Then, when the air passes through the second auxiliary frame 303, the air velocity gradually increases, achieving efficient filtration and sterilization. A set of outwardly moving toothed plates 308 connects the main support 301 with the first and second auxiliary frames 302 and 303. Subsequently, a set of pull rods 404 are moved towards the support rods 307, thereby driving a set of T-shaped limiting rods 403 away from the support. A set of positioning plates 2 is used to release the restriction of the T-shaped limiting rod 403. Then, the upward movement of the main support 301 can drive the first auxiliary frame 302 and the second auxiliary frame 303 to move upward at the same time, thereby removing a set of filter plates 5, which is convenient for quick replacement of the set of filter plates 5. When cleaning the ultraviolet lamp 304 separately, the support rod 307 is rotated after the restriction of the limiting mechanism 4 is released, so that the gear 306 drives a set of toothed plates 308 to move inward. At this time, there is no connection between the main support 301 and the first auxiliary frame 302 and the second auxiliary frame 303, which is convenient for removing the main support 301 separately.

[0033] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
