Description

Technical Field

[0001] This utility model relates to the technical field of formaldehyde treatment devices, and in particular to an activated carbon formaldehyde removal device. Background Technology

[0002] Activated carbon formaldehyde removal devices use the porous structure of activated carbon to adsorb harmful gases such as formaldehyde in the air and fix them in the pores, thereby reducing the formaldehyde concentration in the air. They are widely used in homes, offices and other places.

[0003] According to a public announcement of an activated carbon formaldehyde removal device with high-efficiency filtration function (publication number: CN209188429U), in the above application, the mesh plate can restrict the activated carbon pack, so that the activated carbon pack will not shake inside the shell, thus effectively filtering formaldehyde. By setting a piston and a through hole, workers can remove the activated carbon pack from the shell through the through hole, making it convenient to replace the activated carbon pack. The piston can also block the through hole, so that the air inside the shell will not escape through the through hole.

[0004] The aforementioned patent uses a piston to open the through hole to replace the activated carbon pack. However, the activated carbon pack is confined between two sets of mesh plates, and the opening of the through hole is relatively narrow. Therefore, it is difficult to manually remove the activated carbon pack from the shell through the through hole, making the replacement of the activated carbon pack inconvenient. To address this issue, an activated carbon formaldehyde removal device is proposed. Utility Model Content

[0032] 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.

[0033] Reference Figure 1 - Figure 3This utility model provides an embodiment of an activated carbon formaldehyde removal device, comprising a housing 1. A fan 2 is fixedly installed on the left inner wall of the housing 1, and an air outlet 3 is provided on the right side of the housing 1. When the fan 2 draws outside air into the housing 1, the airflow passes through the activated carbon pack 44 and exits the housing 1 through the air outlet 3. A disassembly and assembly mechanism is provided inside the housing 1, which includes a clamping component 4 and a limiting component 5. The clamping component 4 includes a positioning plate 41, which is slidably connected to the inner wall of the housing 1. A partition 42 is fixedly installed on the inner wall of the positioning plate 41, and a lifting component 6 is provided on the positioning plate 41. A perforated plate 43 is slidably connected to the inner wall of plate 41. An activated carbon bag 44 is placed between the perforated plate 43 and the partition plate 42. The activated carbon bag 44 can be clamped by the perforated plate 43 and the partition plate 42, thereby improving the stability of the activated carbon bag 44 and enabling it to fully exert its formaldehyde removal effect. A sloping groove 45 is opened on the inner wall of the shell 1. An L rod 46 is fixedly installed on the outer wall of the perforated plate 43. The end of the L rod 46 away from the perforated plate 43 is attached to the inner wall of the sloping groove 45. When the positioning plate 41 slides on the inner wall of the shell 1, the L rod 46 and the sloping groove 45 can drive the perforated plate 43 to slide on the inner wall of the positioning plate 41.

[0034] Reference Figure 1 - Figure 3 A positioning shaft 47 is slidably connected through the inner wall of the perforated plate 43. A positioning frame 49 is fixedly installed at one end of the positioning shaft 47, and a positioning block 48 is fixedly installed at the other end of the positioning shaft 47. When the positioning frame 49 contacts the activated carbon bag 44, it will press the activated carbon bag 44 against the outer wall of the partition plate 42, thereby completing the replacement and fixation of the activated carbon bag 44. A positioning spring 410 is fixedly installed on the side of the positioning block 48 near the perforated plate 43, and the end of the positioning spring 410 away from the positioning block 48 is fixedly installed on the outer wall of the perforated plate 43. Through the positioning shaft 47, the positioning block 48 and the positioning spring 410, the positioning frame 49 and the partition plate 42 can clamp activated carbon bags 44 of different thicknesses, improving the overall practicality of the device.

[0035] Reference Figure 1 - Figure 3The limiting component 5 includes a rotating rod 51, which is rotatably connected to the inner wall of the positioning plate 41. A handle 52 is fixedly installed on the outer wall of the rotating rod 51. Pulling the rotating rod 51 through the handle 52 can cause the positioning plate 41 to slide on the inner wall of the housing 1. The handle 52 can also cause the rotating rod 51 to rotate on the inner wall of the positioning plate 41. A locking block 53 is fixedly installed on the outer wall of the housing 1. A limiting rod 54 is slidably connected to the inner wall of the handle 52. One end of the limiting rod 54 is attached to the inner wall of the locking block 53, and the other end of the limiting rod 54 is fixedly installed with a limiting block 55. The positioning plate 41 can be limited by the cooperation between the limiting rod 54 and the locking block 53. A limiting spring 56 is fixedly installed on the side of the limiting block 55 near the handle 52. The end of the limiting spring 56 away from the limiting block 55 is fixedly installed on the outer wall of the handle 52. The elasticity of the limiting spring 56 in cooperation with the limiting block 55 can cause the limiting rod 54 to be attached to the inner wall of the locking block 53.

[0036] Reference Figure 5 - Figure 6 The lifting assembly 6 includes a rotating shaft 61, which passes through and is rotatably connected to the inner wall of the partition 42. Both ends of the rotating shaft 61 extend to the outside of the partition 42 and are fixedly mounted with a top rod 62. When the rotating shaft 61 rotates, it works with the top rod 62 to lift the activated carbon pack 44 between the partition 42 and the positioning frame 49 upward, thereby making it easier for people to take the activated carbon pack 44. A driven bevel gear 63 is fixedly mounted on the outer wall of the rotating shaft 61. The end of the rotating rod 51 away from the handle 52 extends into the inside of the partition 42 and is fixedly mounted with a driving bevel gear 64. The driving bevel gear 64 meshes with the driven bevel gear 63. By rotating the rotating rod 51 through the handle 52, the driving bevel gear 64 and the driven bevel gear 63 can drive the rotating shaft 61 to rotate synchronously on the inner wall of the partition 42.

[0037] Working principle: During use, the fan 2 is started to draw outside air into the housing 1. Two sets of activated carbon packets 44 inside the housing 1 adsorb formaldehyde from the air. When the activated carbon packets 44 are saturated and need to be replaced, first push the limiting block 55 to compress the limiting spring 56, causing the limiting rod 54 to slide against the inner wall of the handle 52. Once the limiting rod 54 slides out from inside the locking block 53, the limiting on the handle 52 is released. Then, pull the handle 52, causing it to pull the rotating rod 51, which in turn pulls the positioning plate 41. The positioning plate 41 gradually slides out from inside the housing 1. At this point, the positioning plate 41 causes the partition plate 42 and the perforated plate 43 to move synchronously, thus moving the perforated plate 43 and the partition plate 42. As the activated carbon pack 44 between plates 42 moves out of the housing 1, the perforated plate 43 moves, causing the L-rod 46 to move against the inner wall of the inclined groove 45. Under the guidance of the inclined groove 45, the L-rod 46 causes the perforated plate 43 to slide against the inner wall of the positioning plate 41, thereby causing the perforated plate 43 to gradually move away from the partition 42. At the same time, the perforated plate 43 causes the positioning shaft 47 to move synchronously. As the positioning shaft 47 moves, it causes the positioning frame 49 to gradually move away from the partition 42, thereby allowing the positioning frame 49 to release the clamp on the activated carbon pack 44. As the activated carbon pack 44 gradually moves out of the housing 1, it is convenient to manually remove the activated carbon pack 44 between the partition 42 and the positioning frame 49 for replacement.

[0038] The replaced activated carbon pack 44 is placed between the partition plate 42 and the positioning frame 49. Then, the positioning plate 41 is pushed into the housing 1. At the same time, under the guidance of the inclined groove 45 and with the help of the L rod 46, the perforated plate 43 can be driven to gradually approach the partition plate 42. As the perforated plate 43 approaches the partition plate 42, it can be driven to gradually approach the positioning frame 49 with the help of the positioning shaft 47. When the positioning frame 49 contacts the activated carbon pack 44, it will press the activated carbon pack 44 against the outer wall of the partition plate 42, thereby completing the replacement and fixing of the activated carbon pack 44. Furthermore, through the positioning shaft 47, the positioning block 48 and the positioning spring 410, the positioning frame 49 and the partition plate 42 can clamp activated carbon packs 44 of different thicknesses, so as to make flexible adjustments according to the different contents of activated carbon packs 44, thereby improving the overall practicality of the device.

[0039] After the positioning plate 41 moves the saturated activated carbon pack 44 out of the housing 1, the handle 52 rotates the rotating rod 51, causing the rotating rod 51 to drive the drive bevel gear 64 to rotate. At the same time, the drive bevel gear 64 rotates, causing the driven bevel gear 63 meshing with it to rotate synchronously. At the same time, the driven bevel gear 63 rotates, causing the rotating shaft 61 to rotate synchronously on the inner wall of the partition 42. At the same time, the rotating shaft 61 rotates, causing the top rods 62 at both ends of it to swing upward. At this time, the top rods 62 will lift the activated carbon pack 44 between the partition 42 and the positioning frame 49 upward, which makes it easier for people to take out the activated carbon pack 44 so as to quickly replace the activated carbon pack 44.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
