[0002] Nowadays, people are paying more and more attention to the indoor environment, and the interior decoration industry is booming as a result. However, the use of a large number of decorative materials in decoration often leads to excessive formaldehyde levels indoors. As a volatile organic compound, formaldehyde seriously threatens human health, especially children, pregnant women and the elderly and other people with weak immune systems. Therefore, it is urgent to develop efficient formaldehyde removal devices.

[0003] In existing technologies, after prolonged use of indoor decoration environmental formaldehyde removal devices, a large amount of harmful substances accumulate on the filter screen. When the activated carbon filter reaches saturation with adsorbed formaldehyde, there is a risk that the adsorbed formaldehyde may be released under certain external conditions, such as temperature. Furthermore, because some filter screens are fixed with bolts, operators often need to use tools such as thread cutters and electric drills to disassemble and remove the filter screens, and each bolt needs to be removed individually, which takes a lot of time and is quite complicated.

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.

[0030] Reference Figure 1 - Figure 3This utility model provides an embodiment of an environmentally friendly formaldehyde removal device for indoor decoration, comprising a housing 1 for accommodating the entire device, an air outlet 2 for discharging filtered gas on the inner wall of the housing 1, an extension component 3 for extending the filtration range of the device and enhancing the adsorption force on corners on the right end of the housing 1, an air inlet grille 5 for allowing external gas to enter the housing 1 rotatably connected to the front surface of the housing 1, a quick-release component 6 for quickly assembling and disassembling an activated carbon filter 4 on the inner wall of the housing 1, the quick-release component 6 including a support plate 61 for supporting the activated carbon filter 4, a slider 62 for continuously supporting the support plate 61 fixedly connected to the left surface of the support plate 61, a connecting plate 65 for moving the support plate 66 when the pressing rod 64 moves slidably connected to the inner wall of the support plate 61, and a pressing rod 64 for facilitating the operator to move the support plate 66 fixedly connected to the upper surface of the connecting plate 65. The upper surface of the support plate 61 is fixedly connected to a handle 63 for easy operation by the operator to pull out the support plate 61. The rear surface of the connecting plate 65 is fixedly connected to a support plate 66 for supporting the insert rod 68 of the upper surface. The lower surface of the support plate 66 is fixedly connected to a return spring 67 for automatic reset after the support plate 66 moves and for continuous support of the activated carbon filter 4 during daily use. The lower end of the return spring 67 is fixedly connected to the inner wall of the support plate 61. The upper surface of the support plate 66 is fixedly connected to an insert rod 68 for inserting into the inner wall of the activated carbon filter 4 to fix the activated carbon filter 4 in the left and right directions. The outer wall of the insert rod 68 is inserted with an activated carbon filter 4 for adsorbing formaldehyde inside the box 1. The upper end of the activated carbon filter 4 is inserted into the inner wall of the box 1. The exhaust fan 7 is provided with slots 37 for matching the activated carbon filter 4. The inner wall of the box 1 is provided with an exhaust fan 7 for drawing outside air into the box 1.

[0031] Reference Figure 1 - Figure 3 The outer wall of the slider 62 is slidably connected to the inner wall of the housing 1, the outer wall of the pressing rod 64 is slidably connected to the inner wall of the handle 63, the outer wall of the support plate 66 is slidably connected to the inner wall of the support plate 61, and the extension assembly 3 includes a winding reel 31 for storing the air tube 32 so that the air tube 32 has sufficient length when in use. The left surface of the winding reel 31 is fixedly connected to the right surface of the housing 1, and the inner wall of the winding reel 31 is provided with an air tube 32 for guiding the gas sucked in by the suction head 310 into the interior of the housing 1.

[0032] Reference Figure 2 - Figure 4The right end of the air tube 32 is fixedly connected to a rigid tube 39, which, through its own characteristics, allows the inhalation head 310 to penetrate into corners without bending or deflecting. The other end of the air tube 32 is fixedly and penetrates the inner wall of the housing 1. The right surface of the reel 31 is fixedly connected to an adjustment disc 33, which works with the adjustment rod 35 to adjust the swing angle of the handle 36. The inner wall of the adjustment disc 33 is provided with a slot 37 for accommodating the adjustment rod 35. The inner wall of the slot 37 is fitted with different slots 37 to adjust the swing angle of the handle 36. The left surface of the adjustment rod 35 is elastically connected to the left end of the handle 36 via a support spring 34. The outer wall of the adjustment rod 35 is slidably connected to the handle 36 for the operator to adjust the angle of the rigid tube 39. The lower surface of the handle 36 is fixedly connected to a spring piece 38 for fixing and clamping the rigid tube 39. The outer wall of the rigid tube 39 is engaged with the inner wall of the spring piece 38. The right surface of the rigid tube 39 is fixedly connected to an air intake head 310 to help the rigid tube 39 better collect gas in order to remove formaldehyde. The slider 62 is T-shaped.

[0033] Working principle: First, place the device in the desired position, then hold and pull the adjustment lever 35 to gradually disengage it from the slot 37. At this point, swing the handle 36 to a suitable angle. The swinging of the handle 36 moves the spring 38, simultaneously adjusting the orientation of the rigid tube 39 and the suction head 310, allowing the device to operate more effectively. Furthermore, by pressing down firmly on the rigid tube 39, it can be disengaged from the control of the spring 38. This allows the suction head to be inserted into areas with poor airflow for better formaldehyde removal. If the activated carbon filter 4 needs replacement or is damaged, it can be replaced by pressing... Press down the pressing rod 64, which in turn moves the connecting plate 65 and simultaneously moves the support plate 66. At this time, the return spring 67 undergoes elastic deformation. Continue to press down the pressing rod 64 until the upper end of the activated carbon filter 4 is disengaged from the slot near the exhaust fan 7 of the housing 1. Then, pull out the support plate 61 and remove the activated carbon filter 4 along the insertion rod 68. Take out a new activated carbon filter 4 and insert it into the outer wall of the insertion rod 68. Push the support plate 61 in and release the pressing rod 64. At this time, the return spring 67 moves the activated carbon filter 4 into the slot near the exhaust fan 7 and continues to support the activated carbon filter 4, thus completing the operation.
