Technical Field

[0001] The utility model relates to the technical field of formaldehyde removal equipment, in particular to formaldehyde removal equipment. Background Art

[0002] Formaldehyde is a significant indoor air pollutant. It poses significant health risks, primarily due to its irritating effects on the skin and mucous membranes. When indoor formaldehyde concentrations reach a certain level, it can cause discomfort, including red eyes, eye pain, sore throat, sneezing, dermatitis, chest tightness, and shortness of breath. This can pose a significant threat to human health and can even lead to serious illnesses, including respiratory irritation, abdominal pain, convulsions, allergic dermatitis, pigmentation, skin necrosis, and even death.

[0003] In the prior art, a utility model patent with announcement number CN219964257U provides a photocatalyst formaldehyde removal device, including a chassis, an air inlet is opened on the left side of the chassis, and an air collecting hood is integrally formed on the side of the air inlet of the chassis, a baffle frame is provided in the air inlet, a dustproof component is provided in the air inlet, the dustproof component is located on the left side of the baffle frame, a limiting component is provided in the air inlet, and the limiting component is used to limit the dustproof component in the air inlet; and an elastic component is provided between the dustproof component and the baffle frame.

[0004] The photocatalyst formaldehyde removal device requires pushing two sets of limit rods at the same time, which makes it impossible to replace the filter with one hand. At the same time, the wind collecting hood easily affects the operation with both hands, making it inconvenient to disassemble and install the filter, affecting the efficiency of replacing the filter. The outer opening of the wind collecting hood cannot be sealed, resulting in dust and other debris easily entering the wind collecting hood and air inlet when the device is idle. For this reason, we propose a formaldehyde removal device to solve the above problems. Utility Model Content

Connect to the mounting seat 51, the mounting seat 51 is a circular ring structure, the inner wall of the mounting seat 51 is provided with a thread, the filter screen 4 is a disc-shaped structure, the curved wall of the filter screen 4 is provided with a thread matching the inner wall of the mounting seat 51, and the mounting groove 52 is provided with at least two groups symmetrically distributed on one side wall of the filter screen 4. The outer wall of the insertion rod 53 inserted into the mounting groove 52 is wrapped with an anti-slip sleeve 54 at one end. The anti-slip sleeve 54 is made of anti-slip rubber material. The anti-slip sleeve 54 frictionally contacts the inner wall of the mounting groove 52, and the length of the anti-slip sleeve 54 is less than or equal to the length of the mounting groove 52.

[0022] First, move the filter 4 and put the mounting groove 52 on one end of the insertion rod 53. The anti-slip sleeve 54 rubs against the mounting groove 52 to prevent the filter 4 from sliding freely. Then move the cover plate 61 and align the filter 4 with the mounting seat 51 through the insertion rod 53. Then rotate the cover plate 61 and make the filter 4 rotate along with the insertion rod 53. The filter 4 rotates and is threadedly connected to the mounting seat 51 to complete the installation. Then pull the cover plate 61 outward and take out the insertion rod 53. This makes it easy to disassemble and assemble the filter 4 and improves the efficiency of replacing the filter 4.

[0023] The free end of the insertion rod 53 is connected to a sealing device 6, which is used to seal the outer end of the wind collecting hood 2. The sealing device 6 includes a cover plate 61 arranged at the free end of the insertion rod 53. A rubber pier 62 is provided on the side of the cover plate 61 away from the insertion rod 53. The rubber pier 62 moves and is inserted into the card slot 63 to seal the cover plate 61 on the outer end of the wind collecting hood 2. The size of the cover plate 61 is larger than the size of the opening at the outer end of the wind collecting hood 2. The cover plate 61 is made of visible material, the rubber pier 62 is made of rubber material, and the card slot 63 is provided with two groups symmetrically distributed on the outer end of the wind collecting hood 2.

[0024] When the equipment is idle, align the rubber block 62 on the cover 61 with the slot 63, and insert the rubber block 62 into the slot 63 to complete the work of covering the cover 61 on the outer end of the wind collecting hood 2, so that the outer end opening of the wind collecting hood 2 can be covered to prevent debris from entering the wind collecting hood 2 and the air inlet 7 when the equipment is idle.

[0025] Working principle: The utility model first moves the filter 4, and puts the installation groove 52 on one end of the insertion rod 53. The anti-slip sleeve 54 rubs and contacts the installation groove 52 to prevent the filter 4 from sliding freely. Then move the cover plate 61, align the filter 4 with the mounting seat 51 through the insertion rod 53, and then rotate the cover plate 61. The filter 4 is rotated and connected with the mounting seat 51 through the insertion rod 53. The filter 4 rotates and is threadedly connected with the mounting seat 51 to complete the installation work. Then pull the cover plate 61 outward and take out the insertion rod 53, which makes it easy to disassemble and assemble the filter 4 and improves the efficiency of replacing the filter 4. When the equipment is idle, align the rubber pier 62 on the cover plate 61 with the card slot 63, and snap the rubber pier 62 into the card slot 63 to complete the work of the cover plate 61 covering the outer end of the wind collecting hood 2, so that the outer end opening of the wind collecting hood 2 can be covered to prevent debris from entering the wind collecting hood 2 and the air inlet 7 when the equipment is idle.

[0026] The chassis 1, the air inlet 7, the air collecting cover 2 and the baffle 3 are all existing technologies and will not be described in detail here.
