Abstract
Description
Technical Field
[0001] This utility model relates to the field of air purification technology, and in particular to a suspended formaldehyde removal device. Background Technology
[0002] Formaldehyde is a common indoor air pollutant, mainly originating from decoration materials, furniture, adhesives, and textiles. Its harm is mainly manifested in its effects on human mucous membranes, immune system, and long-term health. Since formaldehyde floats in the indoor air, and conventional formaldehyde removal devices can usually only be placed on the ground, the formaldehyde floating in the upper layers of the room cannot be fully adsorbed.
[0003] To avoid the above situation, existing technologies have developed formaldehyde removal devices that can be suspended from indoor ceilings, such as the suspended formaldehyde removal device disclosed in the utility model patent with authorization announcement number CN216092726U.
[0004] Although the above-mentioned device can adsorb formaldehyde in the upper part of the room by hanging it, the actual installation and replacement of the power supply battery require the use of ladders or stools for disassembly and assembly. This is not only inconvenient, but also prone to accidents when climbing ladders or stepping on stools, so the actual use effect is not ideal.
[0005] Therefore, it is necessary to invent a suspended formaldehyde removal device to solve the above problems. Utility Model Content
[0006] The purpose of this utility model is to provide a suspended formaldehyde removal device that can be installed and disassembled without the need for ladders or stools, making installation more convenient. It also prevents users from bumping their heads during installation, and the gas suction mechanism can draw in air from higher indoor areas, resulting in better performance. This addresses the problem mentioned in the background art, where installation and battery replacement require ladders or stools, which is inconvenient and prone to accidents, leading to less than ideal performance.
[0007] According to one aspect of this disclosure, the following technical solution is provided: a suspended formaldehyde removal device, comprising:
[0008] A gas extraction mechanism for drawing in formaldehyde-containing gas from the upper part of the room;
[0009] A formaldehyde purification system, wherein the formaldehyde purification system is used to purify gas containing formaldehyde; and
[0010] An adjustable suspension mechanism includes a fixed post fixedly mounted on the top of the mounting housing and a handle B fixedly mounted on the bottom of the mounting housing. A limit post is fixedly mounted on the top outer side of the fixed post. A connecting sleeve is slidably sleeved on the outer side of the fixed post in the vertical direction. An adjusting groove extending in the vertical direction and multiple L-shaped limiting grooves communicating with the adjusting groove are opened on the outer side of the connecting sleeve. The limiting post is located inside the adjacent L-shaped limiting groove. A hook A is fixedly mounted on the top of the connecting sleeve.
[0011] According to at least one embodiment of the suspended formaldehyde removal device of the present disclosure, the gas suction mechanism includes a mounting housing, a fixed channel is provided on the left side of the mounting housing, and an exhaust opening is provided on the back side of the mounting housing.
[0012] According to at least one embodiment of the suspended formaldehyde removal device of this disclosure, a suction fan is fixedly disposed through the left side of the front of the mounting housing, and a battery box electrically connected to the suction fan is fixedly disposed on the right side of the front of the mounting housing.
[0013] According to at least one embodiment of the suspended formaldehyde removal device of the present disclosure, the formaldehyde purification mechanism includes an L-shaped insert plate that is inserted into the inner side of a fixed channel in a horizontal direction and fixed to the fixed channel by friction, and a sealing plate for sealing the fixed channel is fixedly provided at the left end of the L-shaped insert plate.
[0014] According to at least one embodiment of the suspended formaldehyde removal device of this disclosure, a handle A is fixedly provided on the left side of the sealing plate, and three insertion slots are provided on the inner side of the L-shaped insert plate and the inner side of the sealing plate.
[0015] According to at least one embodiment of the suspended formaldehyde removal device of the present disclosure, a dust filter, a formaldehyde removal filter and an activated carbon filter are inserted vertically in sequence from front to back into the three insertion slots.
[0016] The technical effects and advantages of this utility model are as follows:
[0017] This invention features an adjustable suspension mechanism for easy installation. First, the limiting post is moved to the inner side of the lowest L-shaped limiting groove. Then, handle B is removed, and hook A is hooked onto hook B on the ceiling. Next, handle B rotates the mounting housing, causing it to move from the inner side of the lowest L-shaped limiting groove to the inner side of the adjusting groove via the fixing post. Finally, handle B moves the mounting housing upwards, causing the fixing post to move upwards within the connecting sleeve until the user's arm is fully raised. At this point, handle B rotates the fixing post again, causing it to move the limiting post to the inner side of the adjacent L-shaped limiting groove, locking it in place. At this point, the gas extraction mechanism and formaldehyde purification mechanism are positioned at head height. Compared to existing technologies, this invention eliminates the need for ladders or stools during installation and disassembly, making installation more convenient. It also prevents head injuries during installation, and the gas extraction mechanism can draw in air from higher areas of the room, resulting in better performance. Attached Figure Description
[0018] The accompanying drawings illustrate exemplary embodiments of the present disclosure and, together with the description thereof, serve to explain the principles of the present disclosure. These drawings are included to provide a further understanding of the present disclosure and are incorporated in and constitute a part of this specification.

[0026] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.
[0027] Figure 1 This is a schematic diagram of the overall structure of a suspended formaldehyde removal device according to one embodiment of the present disclosure.
[0028] Figure 2 This is a schematic diagram of the gas extraction mechanism 1 and the formaldehyde purification mechanism 2 of a suspended formaldehyde removal device according to one embodiment of the present disclosure.
[0029] Figure 3 This is a schematic diagram of the adjustable suspension mechanism 3 of a suspended formaldehyde removal device according to one embodiment of the present disclosure.
[0030] like Figures 1-3 As shown, the suspended formaldehyde removal device disclosed herein consists of three parts: a gas extraction mechanism 1 (responsible for drawing in formaldehyde-containing gas from the upper layer), a formaldehyde purification mechanism 2 (responsible for filtering and purifying the gas), and an adjustable suspension mechanism 3 (responsible for conveniently adjusting the suspension height). The three parts are integrated into a housing, taking into account both portability and stability. The mechanisms work together: the gas extraction mechanism 1 draws formaldehyde gas from the upper layer of the room into the device, and after being filtered through multiple layers by the formaldehyde purification mechanism 2, the clean gas is discharged from the exhaust port. The adjustable suspension mechanism 3 ensures that the device can be disassembled and maintained without the need for auxiliary tools, and can be operated within the reach of a standing person throughout the entire process.
[0031] like Figure 2As shown in this disclosure, the gas suction mechanism 1 includes a mounting housing 11, which is integrally injection molded from ABS engineering plastic. It is lightweight, resistant to aging, and impact-resistant. A fixed channel 12 is provided on the left side of the mounting housing 11, and an exhaust opening is provided on the back of the mounting housing 11. A suction fan 13 is fixedly installed through the left side of the front of the mounting housing 11. A DC silent suction fan is used to reduce noise during operation. A battery box 14, which is electrically connected to the suction fan 13, is fixedly installed on the right side of the front of the mounting housing 11. The battery box can hold 4 AA batteries. A push-button buckle cover is provided on the outside of the box, which can be opened without tools. The box has a built-in reverse connection protection circuit to prevent the battery from being installed backwards and damaging the fan. It is electrically connected to the suction fan 13 through a wire. It can work continuously for 8-10 hours with a single battery.
[0032] Therefore, the battery inside the battery box 14 can continuously power the suction fan 13, and the suction fan 13 continuously draws indoor air into the mounting housing 11. After being filtered and purified by the formaldehyde purification mechanism 2, the air is finally output through the exhaust port.
[0033] like Figure 2 As shown, in a preferred embodiment, the formaldehyde purification mechanism 2 includes an L-shaped insert plate 21 that is horizontally inserted into the inner side of the fixed channel 12 and fixed to the fixed channel 12 by friction. The insert plate is made of PP plastic. A sealing plate 22 for sealing the fixed channel 12 is fixedly installed at the left end of the L-shaped insert plate 21. This sealing plate 22 is made of the same material as the L-shaped insert plate 21 and is integrally formed. A sealing ring is adhered to the side of the sealing plate 22 near the L-shaped insert plate 21. A handle A23 is fixedly installed on the left side of the sealing plate 22. Three insertion slots 24 are formed on the inner sides of the L-shaped insert plate 21 and the sealing plate 22. The inner sides of the three insertion slots 24 are arranged vertically from front to back. The filter consists of a dust filter 25, a formaldehyde removal filter 26, and an activated carbon filter 27, which are connected in a straight line. The dust filter 25 uses a HEPA H11 grade filter, which can intercept particulate impurities such as PM2.5, dust, and hair in the air, preventing impurities from clogging the subsequent formaldehyde removal filter and extending its service life. The formaldehyde removal filter 26 uses an amino-modified activated carbon filter (loaded with nano titanium dioxide catalyst), which removes formaldehyde through a dual action of "physical adsorption + chemical decomposition". The activated carbon filter 27 uses high iodine value columnar activated carbon (iodine value ≥1000mg / g), which further adsorbs residual odors, TVOCs and other harmful gases from the formaldehyde decomposition, improving the cleanliness of the air outlet.
[0034] Therefore, after indoor air is drawn into the mounting housing 11 by the suction fan 13, the air passes through the dust filter 25, the formaldehyde removal filter 26, and the activated carbon filter 27, and is purified by these filters. Finally, the air is discharged into the room through the exhaust port on the back of the mounting housing 11. When it is necessary to replace the dust filter 25, the formaldehyde removal filter 26, and the activated carbon filter 27, the sealing plate 22 can be moved to the left by the handle A23. The sealing plate 22 will then move the L-shaped insert plate 21 out of the mounting housing 11. Then, depending on the actual situation, the dust filter 25, the formaldehyde removal filter 26, or the activated carbon filter 27 that needs to be replaced can be pulled out upward from the inside of the corresponding insertion slot 24.
[0035] like Figure 3 As shown in this disclosure, the adjustable suspension mechanism 3 includes a fixed post 31 fixedly installed on the top of the mounting housing 11 and a handle B37 fixedly installed on the bottom of the mounting housing 11. The fixed post 31 is an aluminum alloy round rod. A limit post 32 is fixedly installed on the top of the outer side of the fixed post 31. A connecting sleeve 33 is slidably sleeved on the outer side of the fixed post 31 in the vertical direction. The limit post 32 and the connecting sleeve 33 are made of the same material as the fixed post 31. An adjustment groove 34 extending in the vertical direction and a plurality of L-shaped limit grooves 35 communicating with the adjustment groove 34 are opened on the outer side of the connecting sleeve 33. The limit post 32 is located inside the adjacent L-shaped limit groove 35. A hook A36 made of stainless steel is fixedly installed on the top of the connecting sleeve 33.
[0036] Therefore, to facilitate the installation of this device, firstly, the limiting post 32 is moved to the inner side of the lowest L-shaped limiting groove 35. Then, the handle B37 is picked up and the hook A36 is hooked onto the hook B on the ceiling using the handle B37. Then, the mounting housing 11 is rotated using the handle B37, which causes the mounting housing 11 to move the limiting post 32 from the inner side of the lowest L-shaped limiting groove 35 to the inner side of the adjusting slide groove 34 via the fixing post 31. Finally, the mounting housing 11 is moved upwards using the handle B37, which causes the fixing post 31 to move upwards inside the connecting sleeve 33 until the user's arm is fully raised. At this point, the fixing post 31 is rotated again using the handle B37, which causes the fixing post 31 to move upwards. The movable limiting post 32 moves to the inside of the adjacent L-shaped limiting groove 35 to form a lock. At this time, the gas suction mechanism 1 and the formaldehyde purification mechanism 2 are located at the height of the user's head. When it is necessary to replace the battery inside the battery box 14 or replace the dust filter 25, the formaldehyde removal filter 26 and the activated carbon filter 27, you can directly raise your arm, hold the handle B37 and drive the limiting post 32 to move to the inside of the adjusting slide 34, thereby lowering the gas suction mechanism 1 and the formaldehyde purification mechanism 2. Compared with the existing technology, there is no need to use ladders or stools for disassembly and assembly, making the installation more convenient. At the same time, the user's head will not be bumped during installation, and the gas suction mechanism 1 can suck in air from the upper part of the room, resulting in better actual use effect.
[0037] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.
[0038] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
