Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically to a negative ion activated carbon filter. Background Technology

[0002] Activated carbon filters use aluminum honeycomb, plastic honeycomb, or paper honeycomb with a perforated structure as the carrier. They possess the highly efficient adsorption properties of activated carbon and can be used for air purification, removing volatile organic compounds such as formaldehyde, toluene, hydrogen sulfide, chlorobenzene, and other airborne pollutants. They offer advantages such as low air resistance and low energy consumption, and can deodorize and remove odors under certain airflow conditions, purifying the environment with excellent purification effects.

[0003] Existing technologies, such as the utility model with authorization publication number CN213314188U, utilize a sliding groove to facilitate the movement of a baffle within it. Fastening screws allow the baffle to be secured to the groove on a fixing strip, while loosening the screws facilitates removal of the baffle, exposing a plate-removing slot from which the honeycomb activated carbon plate can be taken out, thus achieving convenient replacement of the honeycomb activated carbon plate.

[0004] Currently, there is a lack of negative ion activated carbon filters that facilitate the disassembly and assembly of honeycomb filter shells and filters. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a negative ion activated carbon filter screen, which can be fixed in position with only one bolt, making it convenient to disassemble and assemble the honeycomb filter screen shell and the filter screen.

[0006] This utility model achieves its purpose through the following technical solution:

[0007] A negative ion activated carbon filter, characterized by comprising: a honeycomb filter shell, serving as the core component of the filter, filled with negative ion balls and fruit shell activated carbon for adsorbing and decomposing pollutants in the air; a filter frame, with mounting grooves corresponding to the honeycomb filter shell, and symmetrical vertical grooves on the filter frame, providing structural support, fixing the honeycomb filter shell through the mounting grooves, and providing movement space for the sliders through the vertical grooves; symmetrical filter screens, their edges rotatably connected to the filter frame, and the symmetrical filter screens respectively connected to symmetrical mounting seats, one side for preliminary filtration of large particulate impurities in the air, and the other side for secondary filtration of the purified air, and equipped with installation markings; a first slider and a second slider, respectively disposed in the corresponding mounting grooves; two sets of symmetrical connecting rods, one set of symmetrical connecting rods rotatably connected to the first slider, and the other set of symmetrical connecting rods rotatably connected to the second slider, each connecting rod rotatably connected to the corresponding mounting seat, the movement of the sliders realizing the unfolding and retraction of the filter screen, facilitating replacement and maintenance.

[0008] As a further limitation of this technical solution, the filter frame is fixedly connected to a guide rod corresponding to one of the vertical grooves. The guide rod passes through the first slider and provides guidance for the movement of the first slider, ensuring that the slider moves smoothly in the vertical direction.

[0009] The first slider is fixedly connected to the filter frame by a spring. The spring loops around the guide rod, providing elastic support and reducing vibration and impact during movement. After the bolt is unscrewed, the spring returns to its original position, causing the handle to pop out of the hidden slot for convenient subsequent operation.

[0010] As a further limitation of this technical solution, the second slider is fixedly connected to a lever, which passes through the filter screen frame. The lever is used to manually operate the movement of the second slider, making it convenient for the user to quickly unfold or retract the filter screen.

[0011] As a further limitation of this technical solution, the lever is fixedly connected to the handle, and the filter frame is provided with a hidden groove corresponding to the handle. The handle facilitates manual operation of the lever by the user, and the hidden groove is used to hide the handle, making the filter screen look neater. At the same time, it prevents the handle from moving accidentally when not in operation, and facilitates the installation and use of the filter screen as a whole.

[0012] As a further limitation of this technical solution, a mounting groove is provided on one side of the filter frame, and a bolt is matched with the mounting groove, passing through the filter frame. The second slider is provided with a threaded hole that matches the bolt, used to fix the position of the second slider. The corners of the filter screen are rounded, and the bottom edge is covered with rubber. When the filter screen is vertical, the handle is flush with the upper side of the hidden groove, at which point the bolt is aligned with the threaded hole, making it convenient to screw the bolt into the threaded hole.

[0013] As a further limitation of this technical solution, negative ion balls and fruit shell activated carbon are placed in the honeycomb grooves of the honeycomb filter shell. The ratio of negative ion balls to fruit shell activated carbon is usually 7:3. The surface of the negative ion ball is covered with a layer of activated carbon, and the interior is made of negative ion powder. The negative ion ball can emit negative ions at a concentration of 3000-4000, which can effectively decompose the pollutants adsorbed by the activated carbon particles.

[0014] Compared with related technologies, the negative ion activated carbon filter provided by this utility model has the following beneficial effects:

[0015] (1) The negative ion balls and fruit shell activated carbon filled in the honeycomb groove of the honeycomb filter shell of this device can efficiently adsorb pollutants in the air and extend the service life of activated carbon through the decomposition effect of negative ions.

[0016] (2) With the design of slider, connecting rod and pull rod, this device allows users to easily unfold and retract the filter screen, making it easy to replace and maintain;

[0017] (3) The design of the handle and hidden slot of this device provides a convenient way of operation while maintaining the clean appearance of the filter. Attached Figure Description

[0024] 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.

[0025] Example 1: A negative ion activated carbon filter, comprising: a honeycomb filter shell 11, serving as the core component of the filter, filled with negative ion balls and fruit shell activated carbon for adsorbing and decomposing pollutants in the air; a filter frame 1, with mounting grooves 8 corresponding to the honeycomb filter shell 11, and symmetrical vertical grooves 13, providing structural support, fixing the honeycomb filter shell 11 through the mounting grooves 8, and providing movement space for the slider through the vertical grooves 13; symmetrical filter screens 2, their edges rotatably connected to the filter frame 1, and the symmetrical filter screens 2 respectively connected to the honeycomb filter shell 11. The mounting base 9 has one side for initial filtration of large particulate impurities in the air and the other side for secondary filtration of the purified air, and is marked with an installation symbol. The first slider 14 and the second slider 16 are respectively set in the corresponding mounting slots 8. Two sets of symmetrical connecting rods 10 are provided. One set of symmetrical connecting rods 10 is rotatably connected to the first slider 14, and the other set of symmetrical connecting rods 10 is rotatably connected to the second slider 16. Each connecting rod 10 is rotatably connected to the corresponding mounting base 9. The movement of the sliders enables the filter screen 2 to be unfolded and retracted, facilitating replacement and maintenance.

[0026] The filter frame 1 is fixedly connected to a guide rod 13 corresponding to one of the vertical grooves 13. The guide rod 13 passes through the first slider 14 and provides guidance for the movement of the first slider 14, ensuring that the slider moves smoothly in the vertical direction.

[0027] The second slider 16 is fixedly connected to the lever 7, which passes through the filter frame 1. The lever 7 is used to manually operate the movement of the second slider 16, making it easy for the user to quickly unfold or retract the filter 2.

[0028] The lever 7 is fixedly connected to the handle 6. The filter frame 1 is provided with a hidden groove 3 corresponding to the handle 6. The handle 6 makes it easy for the user to manually operate the lever 7. The hidden groove 3 is used to hide the handle 6, making the filter screen look neater. At the same time, it prevents the handle 6 from moving accidentally when not in operation, and facilitates the installation and use of the filter screen as a whole.

[0029] The filter frame 1 has a mounting groove 4 on one side, and a bolt 5 is fitted into the mounting groove 4. The bolt 5 passes through the filter frame 1. The second slider 16 has a threaded hole that matches the bolt 5, used to fix the position of the second slider 16. The corners of the filter screen 2 are rounded, and the bottom edge is covered with rubber. When the filter screen 2 is vertical, the handle 6 is flush with the upper side of the hidden groove 3. At this time, the bolt 5 is aligned with the threaded hole, making it easy to screw the bolt 5 into the threaded hole.

[0030] Negative ion balls and activated carbon from fruit shells are placed inside the honeycomb grooves of the honeycomb filter shell 11. The ratio of negative ion balls to activated carbon from fruit shells is usually 7:3. The surface of the negative ion balls is covered with a layer of activated carbon, and the interior is made of negative ion powder. The negative ion balls can emit negative ions at a concentration of 3000-4000, effectively decomposing the pollutants adsorbed by the activated carbon particles.

[0031] The working principle of the negative ion activated carbon filter provided by this utility model is as follows:

[0032] Taking disassembly as an example: Unscrew bolt 5, pull handle 6 upwards, handle 6 moves lever 7, lever 7 moves second slider 16, second slider 16 swings one side connecting rod 10, one side connecting rod 10 swings one side mounting seat 9, one side mounting seat 9 swings filter screen 2, filter screen 2 swings the other side mounting seat 9, the other side mounting seat 9 swings the other side connecting rod 10, the other side connecting rod 10 moves first slider 14 along guide rod 12 until filter screen 2 is close to horizontal.

[0033] Example 2: This example is a further elaboration based on Example 1. The first slider 14 is fixedly connected to the filter frame 1 by a spring 15. The spring 15 is looped around the guide rod 13. The spring 15 provides elastic support and reduces vibration and impact during movement. After the bolt 5 is unscrewed, the spring 15 returns to its original position, causing the handle 6 to pop out of the hidden slot 3 for convenient subsequent operation.

[0034] The working principle of the negative ion activated carbon filter provided by this utility model is as follows:

[0035] After unscrewing bolt 5, spring 15 returns to its original state, causing the first slider 14 to move upward, so that handle 6 pops out of hidden slot 3, making it convenient to pull handle 6 upward later. When replacing honeycomb filter shell 11 and filter screen 2, it is necessary to keep handle 6 in the pulling state.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
