Description

Technical Field

[0001] This utility model belongs to the field of air purifier technology, specifically relating to an indoor air purifier with a multi-layer filtration structure. Background Technology

[0002] Air purifiers are household appliances that can adsorb, decompose, or transform various air pollutants (generally including PM2.5, dust, pollen, odors, formaldehyde and other decoration pollution, bacteria, allergens, etc.) to effectively improve air cleanliness. They are mainly divided into household, commercial, industrial, and building types.

[0003] Existing indoor air purifiers are equipped with filtration structures to filter dust in the air. However, these filtration structures gradually become clogged over time, reducing their filtration capacity. This requires regular cleaning, which is cumbersome and makes it difficult to ensure that indoor air purifiers can operate continuously for extended periods.

[0004] Therefore, an indoor air purifier with a multi-layer filtration structure is proposed. Utility Model Content

[0005] This invention provides an indoor air purifier with a multi-layer filtration structure, the purpose of which is to solve the problems mentioned above.

[0006] This utility model provides an indoor air purifier with a multi-layer filtration structure, including an indoor air purifier body; an upper air intake hood and a lower air intake hood disposed on the outer wall of the indoor air purifier body, the upper air intake hood being located above the lower air intake hood; grooves respectively formed at the top inside the upper air intake hood and the bottom inside the lower air intake hood; a rotating shaft rotating on the inner wall of the grooves; a filter baffle disposed on the outer wall of the rotating shaft; a spring disposed between the outer wall of the filter baffle and the inner wall of the grooves; a filter hole penetrating through the outer wall of the filter baffle; a docking groove disposed on the outer wall of the filter baffle adjacent to the filter hole; a magnetic plate disposed on one side of the filter baffle; a docking strip disposed on the outer wall of the magnetic plate; and connecting plates respectively disposed on the outer walls of the upper air intake hood and the lower air intake hood.

[0007] Furthermore, both the docking groove and the docking strip have T-shaped cross-sections, and the docking groove and the docking strip are slidably connected.

[0008] By adopting the above technical solution, the docking structure facilitates the replacement of magnetic plates, thereby allowing the replacement of magnetic plates with different magnetic adsorption forces as needed, and thus adjusting the constraint force between the two magnetic plates.

[0009] Furthermore, the magnetic plates on the filter baffles in the upper and lower air intake hoods are connected by magnetic adsorption.

[0010] By adopting the above technical solution, it is ensured that the two filter baffles can be magnetically attracted together at a certain angle, providing a limit for the constraint of the two filter baffles.

[0011] Furthermore, the connecting plates on the upper and lower air intake shrouds are fixedly connected by bolts;

[0012] By adopting the above technical solution, it is easy to disassemble and assemble the upper and lower air intake hoods, thereby cleaning the dust that clogs the filter baffle.

[0013] Furthermore, the angle between the filter baffle and the horizontal plane is 45 degrees;

[0014] By adopting the above technical solution, a filter structure can be formed by setting two filter baffles at a 90-degree angle, which increases the filter area and improves the filter efficiency. The inclined filter baffles facilitate rotation under negative pressure.

[0015] Furthermore, an exhaust fan is provided inside the indoor air purifier body on the side near the upper and lower air intake hoods, and an air purification filling layer is provided inside the indoor air purifier body.

[0016] By adopting the above technical solution, the suction force generated by the working of the exhaust fan is used to bring indoor air into the indoor air purifier body, and the air is filtered, purified, and adsorbed through the air purification filling layer to achieve air filtration and purification treatment.

[0017] The beneficial effects of this utility model are as follows:

[0018] This invention utilizes the difference between the negative pressure of the air purifier and the spring tension and the magnetic attraction force of the magnetic plate to rotate the filter baffles, thereby opening a filter structure formed by the combination of two filter baffles. This multi-stage filtration system sequentially filters dust from the air. Once the filter structure is opened, the dust on it does not need immediate cleaning, reducing the frequency of cleaning and increasing the continuous operating time of the air purifier itself. By replacing the magnetic plates, different magnetic attraction forces can be used as needed, thereby adjusting the constraint force between the two magnetic plates. This ensures that the filter baffles rotate when they become clogged to a certain extent, opening the filter structure and preventing blockage of the air inlet of the air purifier.

[0019] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained by means of the structures particularly pointed out in the description and the drawings. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] Reference Figure 1-4 This utility model embodiment proposes an indoor air purifier with a multi-layer filtration structure, including an indoor air purifier body 1. An upper air intake hood 2 and a lower air intake hood 3 are provided on the air inlet on the outer side wall of the indoor air purifier body 1. The upper air intake hood 2 is located above the lower air intake hood 3. An exhaust fan is provided inside the indoor air purifier body 1 near the upper air intake hood 2 and the lower air intake hood 3. An air purification filling layer is provided inside the indoor air purifier body 1. The suction force generated by the operation of the exhaust fan allows indoor air to enter the indoor air purifier body 1, and the air is filtered, purified, and adsorbed through the air purification filling layer to achieve air filtration and purification treatment.

[0028] The upper air intake hood 2 and the lower air intake hood 3 are both provided with grooves 4 at the top and bottom of the interior. A rotating shaft 5 is rotatably connected to the inner wall of the groove 4. A filter baffle 6 is provided on the outer wall of the rotating shaft 5 near the inner side of the groove 4. The angle between the filter baffle 6 and the horizontal plane is 45 degrees. By setting the two filter baffles 6 at a 90-degree angle, a filter structure can be formed, which increases the filter area and improves the filter efficiency. The inclined filter baffle 6 is convenient to rotate under negative pressure. A spring 7 is provided between the outer wall of the filter baffle 6 and the inner wall of the groove 4. A filter hole 8 is provided through the outer wall of the filter baffle 6. A docking groove 9 is provided at the center of the outer wall of the filter baffle 6 adjacent to the filter hole 8. A magnetic plate 10 is provided on one side of the docking groove 9. The magnetic plates 10 on the filter baffles 6 in the upper air intake hood 2 and the lower air intake hood 3 are connected by magnetic adsorption, which ensures that the two filter baffles 6 can be magnetically adsorbed together at a certain angle, providing a limit for the constraint of the two filter baffles 6.

[0029] A docking strip 11 is provided at the center of one outer wall of the magnetic plate 10. The cross-section of both the docking groove 9 and the docking strip 11 is T-shaped, and the docking groove 9 and the docking strip 11 are slidably connected. The docking structure facilitates the replacement of the magnetic plate 10, thereby allowing the replacement of magnetic plates 10 with different magnetic adsorption forces as needed, and thus adjusting the constraint force between the two magnetic plates 10.

[0030] Connecting plates 12 are provided on the outer side walls of the upper air intake hood 2 and the lower air intake hood 3. The connecting plates 12 on the upper air intake hood 2 and the lower air intake hood 3 are fixedly connected by bolts, which facilitates the disassembly and assembly of the upper air intake hood 2 and the lower air intake hood 3, thereby cleaning the dust clogging the filter baffle 6.

[0031] The specific implementation method is as follows: When the indoor air purifier body 1 is purifying the air indoors, the exhaust fan inside the indoor air purifier body 1 works to draw in the indoor air. The air passes through the upper air intake hood 2 and the lower air intake hood 3 and enters the indoor air purifier body 1. The two filter baffles 6 form a filter structure. The filter holes 8 on the filter baffles 6 intercept the dust in the air and achieve air filtration. The filtered air enters the indoor air purifier body 1 for subsequent purification and adsorption, and is finally discharged into the room to achieve indoor air purification treatment.

[0032] As the indoor air purifier body 1 continues to be used, more and more dust is adsorbed on the filter baffle 6, which gradually becomes clogged, and the air circulation rate gradually decreases. When the filter baffle 6 becomes clogged to a certain extent, the negative pressure generated in the space inside the upper air intake hood 2 and the lower air intake hood 3 near the indoor air purifier body 1 gradually increases. When the sum of the negative pressure and the tension of the spring 7 is greater than the magnetic attraction force of the two magnetic plates 10, the filter baffle 6 is pulled and moves axially along the rotating shaft 5. The filter baffle 6 rotates to the inside of the groove 4. At this time, the first filtration structure is opened, and the second filtration structure inside the upper air intake hood 2 and the lower air intake hood 3 performs subsequent filtration of the air, realizing multi-layer filtration, reducing the number of times dust is cleaned, and increasing the continuous use time of the indoor air purifier body 1 itself.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
