Description

Technical Field

[0001] This utility model relates to the field of air purifier technology, specifically to an air purifier that absorbs fine particulate matter. Background Technology

[0002] Fine particulate matter, also known as fine particles, PM2.5, has an equivalent diameter of ≤2.5 micrometers. It can remain suspended in the air for a relatively long time. The higher its concentration in the air, the more serious the air pollution, and it has a significant impact on air quality and visibility. The primary function of an air purifier is to remove fine particulate matter from the air, including allergens and indoor PM2.5.

[0003] Existing technologies, such as the one with authorization notice number CN218687387U, prevent fine particles from falling into the locking mechanism during the filter's movement, thus reducing the likelihood of fine particles contaminating the filter tray. This solves the problem of fine particles easily contaminating the filter tray when replacing the filter in existing air purifiers.

[0004] Currently, there is a lack of air purifiers that allow for easy filter replacement, preventing fine particulate matter from falling into the air purifier's interior. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an air purifier that absorbs fine particulate matter, which facilitates the replacement of the filter and prevents fine particulate matter from falling into the air purifier.

[0006] This utility model achieves its purpose through the following technical solution:

[0007] An air purifier for absorbing fine particulate matter, characterized by comprising: an air purifier fixedly connected to a mounting frame, the mounting frame being fixedly connected to an inner guide rod; a mounting frame fixedly connected to a middle guide rod; a grille wall fixedly connected to an outer guide rod; a filter screen fitted to the mounting frame, the filter screen being installed within the mounting frame for filtering fine particulate matter in the air; and a parallel unfolding assembly connecting the outer guide rod, the middle guide rod, and the inner guide rod for enabling the unfolding and retraction of the filter screen, facilitating operation and easy filter screen replacement.

[0008] As an optimization, the parallel unfolding assembly includes three fixed blocks and three movable blocks. The outer guide rod, the middle guide rod, and the inner guide rod pass through the corresponding fixed blocks and the corresponding movable blocks, respectively. The outer guide rod, the middle guide rod, and the inner guide rod are fixedly connected to the corresponding fixed blocks. By moving the movable blocks along the guide rods, the filter screen can be unfolded and stored, facilitating filter screen replacement and maintenance.

[0009] As an optimization, each of the fixed blocks and each of the movable blocks is rotatably connected to one end of the connecting rod, and the centers of each set of symmetrical connecting rods are coaxially and rotatably connected, so that when the grid wall is pulled outward, the filter screen is moved.

[0010] As an optimization, the middle movable block is fixedly connected to the U-plate, the U-plate is fixedly connected to the push plate, the push plate matches the mounting frame, and the push plate matches the filter screen. When the filter screen moves outward, the push plate contacts the filter screen and pushes it to move along the mounting frame, making it easy to remove the filter screen.

[0011] As an optimization, the grille wall is fixedly connected to a sealing frame, and the mounting frame matches the sealing frame. This ensures that air does not leak from the side when passing through the filter, improving filtration efficiency. Simultaneously, it prevents unfiltered air from directly entering the purified area, ensuring the air purifier's performance. When the filter is removed, fine particles mainly concentrate in the area comprised of the filter, mounting frame, and sealing frame. As the filter moves away from the air purifier, the mounting frame detaches from the sealing frame, preventing fine particles from falling into the air purifier.

[0012] As an optimization, the mounting frame is fixedly connected to the positioning piece of the filter screen to achieve the positioning of the filter screen.

[0013] As an optimization, the air purifier is provided with a removal slot corresponding to the grille wall, which makes it easy for operators to remove the grille wall from the air purifier, thereby facilitating filter replacement or other maintenance operations, and improving the maintainability and ease of operation of the device.

[0014] Compared with related technologies, the air purifier for absorbing fine particulate matter provided by this utility model has the following beneficial effects:

[0015] (1) This device uses a parallel unfolding component, which allows the filter screen to be unfolded and stored, making it easy to replace and maintain. The filter screen filters fine particulate matter in the air, improving air quality.

[0016] (2) This device uses a sealed frame to ensure that air does not leak when passing through the filter, thus improving filtration efficiency and performance. When the filter is away from the air purifier, the mounting frame detaches from the sealed frame to prevent fine particles from falling into the air purifier. Attached Figure Description

[0022] 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.

[0023] Example 1: An air purifier for absorbing fine particulate matter includes: an air purifier 1, the air purifier 1 being fixedly connected to a mounting frame 9, the mounting frame 9 being fixedly connected to an inner guide rod 10; a mounting frame 5, fixedly connected to a middle guide rod 11; a grille wall 3, fixedly connected to an outer guide rod 7; a filter 14, fitted to the mounting frame 5, the filter 14 being installed inside the mounting frame 5 for filtering fine particulate matter in the air; and a parallel unfolding assembly, connecting the outer guide rod 7, the middle guide rod 11, and the inner guide rod 10, for realizing the unfolding and storage functions of the filter 14, providing convenient operation and easy replacement of the filter 14.

[0024] The parallel unfolding assembly includes three fixed blocks 13 and three movable blocks 16. The outer guide rod 7, the middle guide rod 11, and the inner guide rod 10 pass through the corresponding fixed blocks 13 and the corresponding movable blocks 16, respectively. The outer guide rod 7, the middle guide rod 11, and the inner guide rod 10 are fixedly connected to the corresponding fixed blocks 13. By moving the movable blocks 16 along the guide rods, the filter screen 14 can be unfolded and retracted, facilitating filter screen replacement and maintenance.

[0025] Each of the fixed blocks 13 and each of the movable blocks 16 are rotatably connected to one end of the connecting rod 12. The centers of each set of symmetrical connecting rods 12 are coaxially and rotatably connected, so that when the grid wall 3 is pulled outward, the filter screen 14 is moved.

[0026] The grille wall 3 is fixedly connected to the sealing frame 4, and the mounting frame 5 matches the sealing frame 4. This ensures that air does not leak from the side when passing through the filter 14, improving filtration efficiency. Simultaneously, it prevents unfiltered air from directly entering the purified area, ensuring the performance of the air purifier. When the filter 14 is removed, fine particles mainly concentrate in the area composed of the filter 14, mounting frame 5, and sealing frame 4. As the filter 14 moves away from the air purifier 1, the mounting frame 5 detaches from the sealing frame 4, preventing fine particles from falling into the air purifier 1.

[0027] The mounting frame 5 is fixedly connected to the positioning piece 15 corresponding to the filter screen 14, thereby positioning the filter screen 14.

[0028] The air purifier 1 is provided with a take-out slot 2 corresponding to the grille wall 3, which makes it easy for operators to take out the grille wall 3 from the air purifier 1, thereby facilitating the replacement of the filter screen 14 or other maintenance operations, improving the maintainability and ease of operation of the device.

[0029] The grille wall 3 is connected to the air purifier 1 by a snap-fit ​​connection.

[0030] The working principle of the air purifier that absorbs fine particulate matter provided by this utility model is as follows:

[0031] When replacing filter 14, pull the grille wall 3 outward. The grille wall 3 moves the sealing frame 4, outer guide rod 7, outer fixing block 13, and outer moving block 16. The outer moving block 16 moves the outer connecting rod 12, which in turn moves the outer moving block 16 along the outer guide rod 7. The outer connecting rod 12 moves the middle fixing block 13, middle moving block 16, middle guide rod 11, mounting frame 5, and filter 14 outward, while the middle moving block 16 moves along the middle guide rod 11. The middle moving block 16 moves the inner connecting rod 12, which in turn moves the inner moving block 16 along the inner guide rod 10. The mounting frame 5 moves along the sealing frame 4. When the mounting frame 5 moves out of the air purifier 1 area, the mounting frame 5 disengages from the sealing frame 4. Remove the old filter 14 from the mounting frame 5 and install the new filter 14 into the mounting frame 5, ensuring it contacts the positioning piece 15. Move the grille wall 3 in the reverse direction to install the grille wall 3.

[0032] Example 2: This example is a further elaboration based on Example 1. The moving block 16 in the middle is fixedly connected to the U plate 8, the U plate 8 is fixedly connected to the push plate 6, the push plate 6 matches the mounting frame 5, and the push plate 6 matches the filter screen 14. When the filter screen 14 moves outward, the push plate 6 contacts the filter screen 14 and pushes it to move along the mounting frame 5, which facilitates the removal of the filter screen 14.

[0033] The working principle of the air purifier that absorbs fine particulate matter provided by this utility model is as follows:

[0034] When replacing the filter screen 14, the intermediate moving block 16 drives the U-plate 8 to move, and the U-plate 8 drives the push plate 6 to move, so that the push plate 6 contacts the filter screen 14 and pushes it to move along the mounting frame 5, so that its end is separated from the mounting frame 5. The old filter screen 14 is taken out from the mounting frame 5. The grid wall 3 is moved in the opposite direction, so that the push plate 6 is away from the mounting frame 5. The new filter screen 14 is installed into the mounting frame 5, so that it contacts the positioning piece 15. The grid wall 3 is moved in the opposite direction, and the grid wall 3 is installed.

[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
