Description

Technical Field

[0001] This utility model relates to the field of air purifier technology, specifically to a formaldehyde-removing air purifier that is easy to disassemble and assemble. Background Technology

[0002] Formaldehyde is a toxic gaseous chemical substance, colorless with a pungent odor, and easily soluble in water. It mainly comes from furniture, decoration materials, etc., and is a common indoor pollutant. Long-term exposure to high concentrations of formaldehyde is harmful to human health, including irritating the eyes, nose, and throat, and increasing the risk of cancer. An air purifier is a device used to purify indoor air and remove pollutants, which can improve air cleanliness and protect respiratory health.

[0003] Existing air purifiers primarily rely on the adsorption of activated carbon to effectively remove formaldehyde from indoor air, thereby improving air quality. Therefore, during formaldehyde removal, the filter needs to be replaced regularly. The filter is typically fixed to the air purifier with bolts. Furthermore, since the filter also filters dust and other impurities from the air during use, some dust can be generated during filter replacement due to shaking. To facilitate convenient and stable filter replacement and further reduce dust generation during replacement, a formaldehyde-removing air purifier that is easy to install and remove is now available, eliminating the drawbacks of existing devices.

[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0040] In one embodiment, such as Figures 1-5 As shown, the formaldehyde removal air purifier that is easy to assemble and disassemble includes a purifier body 1. A support plate 6 is fixedly connected to the inner wall of the purifier body 1. Two air inlets 4 are symmetrically opened on the outer wall of the purifier body 1. A filter element 3 is installed inside the purifier body 1. The filter element 3 is located below the support plate 6. Two fixing rings 5 ​​are symmetrically fixedly connected to the outer wall of the filter element 3. The two fixing rings 5 ​​are located at the upper and lower ends of the filter element 3, respectively. An exhaust port 8 is opened at the top of the purifier body 1. A fan assembly 7 is fixedly connected to the top of the inner wall of the purifier body 1 by bolts. The fan assembly 7 is located between the exhaust port 8 and the support plate 6. Dust filters are installed inside the exhaust port 8 and the two air inlets 4. A replacement mechanism for easy replacement of the filter element 3 is provided on the purifier body 1.

[0041] The replacement mechanism includes: a limiting component installed on the main body 1 of the purifier;

[0042] The limiting component includes: two limiting guide frames 204 symmetrically arranged inside the purifier body 1, the two limiting guide frames 204 being fixedly connected to the purifier body 1 and the support plate 6 respectively, the two limiting guide frames 204 being sleeved on the outer walls of two fixing rings 5 ​​respectively, and two limiting guide plates being symmetrically fixedly connected to the inner walls of the two limiting guide frames 204, the fixing rings 5 ​​being sleeved on the outer walls of the limiting guide plates, and the fixing rings 5 ​​being slidably connected to the limiting guide frames 204 and the limiting guide plates;

[0043] The support plate 6 is provided with a plug-in assembly for plugging and fixing the filter element 3;

[0044] The insertion assembly is a docking cylinder 208 disposed above the support plate 6. The docking cylinder 208 penetrates through the support plate 6 to the interior of the filter element 3, and the docking cylinder 208 is slidably connected to the support plate 6.

[0045] A rotating component is provided on the docking sleeve 208;

[0046] A lifting assembly is provided on the docking sleeve 208;

[0047] In this embodiment, when in use, the fan assembly 7 can draw air from the inner cavity of the filter element 3 through the docking tube 208, and at the same time discharge the drawn air to the outside through the exhaust port 8. At this time, the outside air enters the inner cavity of the filter element 3 through the air inlet 4 and the main body of the purifier 1, so that impurities such as formaldehyde in the air can be filtered through the filter element 3.

[0048] When the filter element 3 needs to be replaced, the purifier body 1 is opened and the docking cylinder 208 is raised through the replacement mechanism until the docking cylinder 208 and the filter element 3 are separated.

The rack 2013 is slidably sleeved on the outer wall of the fixed guide plate 2014.

[0055] The rack 2013 is equipped with a push component;

[0056] The pushing component includes: a connecting push plate 2012 fixedly connected to the top of the rack 2013, one end of the outer wall of the connecting push plate 2012 being inclined, and a pressing push block 2015 provided at the end of the connecting push plate 2012 away from the gear ring 206. The outer wall of the pressing push block 2015 is in contact with the inclined outer wall of the connecting push plate 2012. A connecting push block 2011 is fixedly connected to the top of the pressing push block 2015. Both the connecting push block 2011 and the pressing push block 2015 are in contact with the inner wall of one end of the purifier body 1. A pressing push rod 2010 is fixedly connected to the end of the connecting push block 2011 away from the connecting push plate 2012. The pressing push rod 2010 extends to the outside of one end of the purifier body 1 and is slidably connected to the purifier body 1. Through the cooperation of the moving component and the pushing component, the gear ring 206 can be driven to rotate.

[0057] In one embodiment, such as Figures 2-4 As shown, the lifting assembly includes:

[0058] A lifting push plate 205 is fixedly connected to the top of the docking cylinder 208. Multiple limiting rods 203 are equidistantly arranged on the outer circumference of the docking cylinder 208. The multiple limiting rods 203 are all fixedly connected to the support plate 6.

[0059] A reset component is provided on the limit rod 203;

[0060] The reset component is a spring 202 sleeved on the outer wall of the limit rod 203. One end of the spring 202 contacts the outer wall of the limit baffle 201, and the other end of the spring 202 contacts the outer wall of the lifting push plate 205. Through the cooperation of the lifting component and the reset component, the docking cylinder 208 can be automatically reset when the filter element 3 is replaced.

[0061] The above embodiments disclose a formaldehyde removal air purifier that is easy to assemble and disassemble. When in use, the fan assembly 7 can draw air from the inner cavity of the filter element 3 through the docking tube 208, and at the same time, the drawn air is discharged to the outside through the exhaust port 8. At this time, the outside air enters the inner cavity of the filter element 3 through the air inlet 4 and the main body of the purifier 1, so that formaldehyde and other impurities in the air can be filtered through the filter element 3.

[0062] When filter element 3 needs to be replaced, open the purifier body 1 and press the push rod 2010 to slide along the inner wall of the purifier body 1. At the same time, the push block 2015, driven by the push rod 2010, pushes the connecting push plate 2012, which has an inclined outer wall, through the connecting push block 2011. At this time, the connecting push plate 2012 drives the rack 2013 to slide along the outer wall of the fixed guide plate 2014 through the compression. Meanwhile, the toothed ring 206 engages with the rack 2013. When the movement is activated, the limiting rotating ring 207 rotates along the inner wall of the support plate 6. At this time, multiple guide sliders 209 are moved synchronously under the drive of the toothed ring 206. Meanwhile, the docking insert 208 pushes the lifting push plate 205 to rise along the outer wall of the limiting rod 203 through the guide groove under the pressure of the guide slider 209. At this time, the lifting push plate 205 retracts through the displacement compression spring 202 until the docking insert 208 and the filter element 3 are separated from each other, thereby releasing the insertion limit of the filter element 3.

[0063] Then, manually pull the filter element 3 out of the inner cavity of the purifier body 1. During this process, the two retaining rings 5 ​​slide along the inner wall of the limiting guide frame 204 and the outer wall of the limiting guide plate under the action of the filter element 3. Then push the new filter element 3 into the inner cavity of the purifier body 1. Then release the push rod 2010. At this time, the above operation is reversed, so that the filter element 3 can be easily replaced and the dust generated during the replacement of the filter element 3 can be further reduced.

[0064] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
