Description

Technical Field

[0001] This utility model relates to the field of plate activated carbon filter technology, specifically a plate activated carbon fiber filter with easily replaceable filter media. Background Technology

[0002] Plate-type activated carbon filters work through a carbon bed. The activated carbon particles that make up the carbon bed have numerous micropores and a huge specific surface area, giving them a strong physical adsorption capacity.

[0003] In the prior art, Chinese Patent Publication No. CN218107148U discloses a plate-type activated carbon filter with easily replaceable filter media. Limiting grooves are provided on both the front and back of the frame. With the use of limiting rods and insert rods, the limiting plate can be positioned. During disassembly, simply pull out the insert rod to release it from the limiting rods, allowing the limiting plate to be removed from the frame. This facilitates the replacement or maintenance of the internal activated carbon filter screen. A motor is installed inside the cover, and with the brush bristles on the connecting rod, the surface of the activated carbon filter screen can be continuously cleaned while the motor is running, preventing dust from adhering to the screen and ensuring its filtration effect. However, the prior art still requires multiple operations to replace the activated carbon filter screen, which is cumbersome and inconvenient. Therefore, those skilled in the art have proposed a plate-type activated carbon fiber filter with easily replaceable filter media to solve the problems mentioned in the background. Utility Model Content

[0004] The purpose of this invention is to provide a plate-type activated carbon fiber filter with easily replaceable filter media, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A plate-type activated carbon fiber filter with easily replaceable filter media includes a frame and further includes:

[0007] A U-shaped card slot is provided within the frame, and an insertion slot aligned with the card slot is provided at the top of the frame;

[0008] A housing that mates with the card slot and the insertion slot, with a filter screen installed inside the housing;

[0009] The inner cavity at the top of the frame is U-shaped. Several fixed rods are installed on both sides of the inner cavity. A first movable frame is slidably mounted on one of the fixed rods, and a second movable frame is slidably mounted on the other fixed rod. Connecting blocks are installed on both the first and second movable frames, and baffles are connected to the connecting blocks.

[0010] A transmission mechanism is provided between the first movable frame and the second movable frame to enable the movement of the two baffles.

[0011] As a further embodiment of this utility model: protective grilles are provided on both sides of the card slot within the frame.

[0012] As a further embodiment of this utility model: the transmission mechanism includes a rotating shaft rotatably disposed at both ends of the inner cavity, a gear mounted on the rotating shaft, racks meshing with the gears are mounted at both ends of the first and second movable frames, and two racks located at the same end are distributed on both sides of the gear, and the rotating shaft is connected to an elastic element.

[0013] As a further embodiment of this utility model: the elastic element includes grooves formed at both ends of the inner cavity, and a coil spring connected to the rotating shaft is provided in the groove.

[0014] As a further improvement of this utility model, a handle is provided on the baffle.

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

[0016] In use, by pulling one of the handles, the baffle is pulled outwards from the insertion slot. Simultaneously, due to the transmission mechanism, the other baffle is also pulled outwards from the insertion slot, thus opening the insertion slot. At this point, the outer casing located in the slot can be removed, and the outer casing of the new filter screen can be inserted into the insertion slot, ensuring that the outer casing is correctly locked into the slot. Releasing the handle at this point causes the baffle to automatically reset under the action of the transmission mechanism and seal the opening of the insertion slot, thereby completing the disassembly and replacement of the filter screen. The entire disassembly and replacement is quick and requires minimal procedures, resulting in excellent performance. Attached Figure Description

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] Please see Figures 1-3 A plate-type activated carbon fiber filter with easily replaceable filter media includes a frame 1, and further includes:

[0023] A U-shaped card slot 3 is provided within the frame 1, and an insertion slot 4 aligned with the card slot 3 is provided at the top of the frame 1;

[0024] The outer casing 5 mates with the card slot 3 and the insertion slot 4, and a filter screen 6 is installed inside the outer casing 5;

[0025] An inner cavity 7 is formed at the top of the frame 1. The inner cavity 7 is U-shaped. Several fixed rods 8 are installed on both sides of the inner cavity 7. A first movable frame 9 is slidably arranged on one fixed rod 8, and a second movable frame 10 is slidably arranged on the other fixed rod 8. A connecting block 16 is installed on both the first movable frame 9 and the second movable frame 10. A baffle 17 is connected to the connecting block 16.

[0026] A transmission mechanism is provided between the first movable frame 9 and the second movable frame 10 to enable the movement of the two baffles 17.

[0027] In use, by pulling one of the handles, the baffle 17 is pulled outwards towards the insertion slot 4. Due to the action of the transmission mechanism, the other baffle 17 will also be pulled outwards towards the insertion slot 4 simultaneously, thus opening the insertion slot 4. At this time, the outer shell 5 located in the slot 3 can be taken out, and the outer shell 5 of the new filter screen 6 can be inserted into the insertion slot 4, ensuring that the outer shell 5 is correctly locked into the slot 3. Then, release the handle, and the baffle 17 will automatically reset under the action of the transmission mechanism and seal the opening of the insertion slot 4, thereby completing the disassembly and replacement of the filter screen 6. The entire disassembly and replacement is relatively quick, requiring no excessive operating procedures, and the effect is excellent.

[0028] In one embodiment, protective grilles 2 are provided on both sides of the slot 3 within the frame 1.

[0029] The protective grilles 2, which are installed inside the frame 1 and located on both sides of the filter screen 6, can effectively protect the filter screen 6 and prevent large objects from directly impacting it.

[0030] In one embodiment, the transmission mechanism includes a rotating shaft 12 rotatably disposed at both ends of the inner cavity 7, a gear 13 mounted on the rotating shaft 12, and racks 11 meshing with the gears 13 mounted at both ends of the first movable frame 9 and the second movable frame 10, with two racks 11 located at the same end distributed on both sides of the gear 13, and the rotating shaft 12 is connected to an elastic element.

[0031] Furthermore, the elastic element includes grooves 14 formed at both ends of the inner cavity 7, and a coil spring 15 connected to the rotating shaft 12 is provided in the grooves 14.

[0032] During use, due to the torsional force of the coil spring 15, the rotating shaft 12 is subjected to torsional elastic force. Under normal conditions, the rotating shaft 12 is subjected to torsional elastic force, which causes the gear 13 to rotate. In conjunction with the meshing of the rack 11, the first moving frame 9 and the second moving frame 10 can be driven to move to the end of the fixed rod 8 near the insertion slot 4, so that the two baffles 17 close and seal the insertion slot 4. When one of the baffles 17 is pulled, the first moving frame 9 or the second moving frame 10 will be driven to move along the fixed rod 8 through the connecting block 16. Due to the meshing of the rack 11 and the gear 13, the second moving frame 10 or the first moving frame 9 will also be driven to move synchronously along the fixed rod 8, thereby achieving synchronization of the two baffles 17.

[0033] In one embodiment, the baffle 17 is provided with a handle to facilitate pulling the baffle 17.

[0034] In use, by pulling one of the handles, the baffle 17 is pulled outwards towards the insertion slot 4. Due to the action of the transmission mechanism, the other baffle 17 will also be pulled outwards towards the insertion slot 4 simultaneously, thus opening the insertion slot 4. At this time, the outer shell 5 located in the slot 3 can be taken out, and the outer shell 5 of the new filter screen 6 can be inserted into the insertion slot 4, ensuring that the outer shell 5 is correctly locked into the slot 3. Then, the handle is released, and the baffle 17 will automatically reset under the action of the transmission mechanism and seal the opening of the insertion slot 4, thereby completing the disassembly and replacement of the filter screen 6. The entire disassembly and replacement is relatively quick, requiring no excessive operating procedures, and the effect is excellent.
