Description

Technical Field

[0001] This utility model belongs to the technical field of air purification equipment, specifically relating to an air purifier with an easy-to-install and remove filter. Background Technology

[0002] As a key device for improving indoor air quality, air purifiers rely on the filtering effect of filters or screens on harmful substances such as particulate matter and gaseous pollutants in the air. In actual use, as the life cycle of the filter ends, users need to regularly disassemble and replace the filter to maintain purification efficiency.

[0003] However, in existing air purifiers, the filter can often be removed by first opening a specific cover, then releasing the clips or removing the fasteners, which makes filter replacement inconvenient.

[0004] On the other hand, the filter screen becomes increasingly dirty over time due to the large amount of dust, microorganisms and particulate pollutants that adhere to its surface during use. In addition, the disassembly path of the filter screen requires the user to come into close contact with the filter screen surface, which can contaminate the user's hands and clothes during the disassembly process. Utility Model Content

[0005] This invention addresses the aforementioned problems in the existing technology by proposing an air purifier that facilitates the installation and removal of filters.

[0006] This utility model can be achieved through the following technical solutions:

[0007] An air purifier with an easy-to-install and remove filter includes:

[0008] The air purifier body has an air inlet chamber and an air outlet chamber, which are connected by a connecting port, and the top of the air inlet chamber is set as an open opening;

[0009] The filter screen has a closed structure and can be vertically inserted into or removed from the air inlet cavity through the open opening along its axial direction. When the filter screen is installed in the air inlet cavity, the filter screen covers the connecting opening.

[0010] As a further improvement of this utility model, the air inlet cavity and the air outlet cavity are respectively located on the upper and lower layers of the air purifier body.

[0011] As a further improvement of this utility model, the air purifier body includes an air outlet base and an air outlet mesh. The air outlet mesh is configured as a cylindrical structure that runs vertically through the air outlet base and is arranged around the outer circumference of the air outlet base. The inner cavity after the air outlet mesh is connected to the air outlet base forms the air outlet cavity.

[0012] As a further improvement of this utility model, the surface of the air outlet mesh is evenly distributed with mesh holes to form an air outlet.

[0013] As a further improvement of this utility model, the top surface of the air outlet base is provided with a partition plate, and the communication port is opened on the partition plate. When the filter screen is installed into the air inlet cavity, the bottom surface of the filter screen abuts against the partition plate and covers the communication port.

[0014] As a further improvement of this utility model, the air purifier body also includes an air inlet mesh, which is configured as a cylindrical structure that runs vertically through the body and is arranged around the edge of the top of the air outlet base.

[0015] As a further improvement of this utility model, the inner cavity formed by the air inlet mesh itself is the air inlet cavity, and the top opening of the air inlet mesh forms the open opening.

[0016] As a further improvement of this utility model, the surface of the air inlet mesh is evenly distributed with mesh holes to form an air inlet.

[0017] As a further improvement of this utility model, the top of the filter screen is provided with a top plate, and the top plate is provided with a handle.

[0018] As a further improvement of this utility model, the bottom surface of the top plate has an outwardly protruding positioning flange, the top plate is mounted on the air inlet net, and the positioning flange is nested and engaged with the inner wall of the air inlet net.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. Allows users to directly install and remove the filter screen vertically through the open opening at the top of the air inlet screen, without having to go through complicated disassembly steps, which greatly simplifies the replacement process. In addition, this disassembly method can prevent the user's clothes from getting dirty, thus improving the user experience.

[0021] 2. The air purifier's air inlet and outlet are both located on the outer circumference of the unit, enabling 360° circumferential air intake and exhaust. This design greatly improves the efficiency of air intake and exhaust, ensuring that the air purifier can quickly process air over a wider area. Simultaneously, through a dual filtration mechanism, it provides cleaner air output, meeting the needs of scenarios with high air quality requirements.

[0022] 3. After air enters the air inlet chamber through the air inlet screen, it enters the inner cavity of the filter screen from all sides, achieving the first filtration. Then, it enters the air outlet chamber from the bottom of the filter screen through the connecting port. During this process, the air that has been filtered once passes through the filter screen again and achieves a second filtration. This dual filtration mechanism ensures that even tiny particles can be effectively captured, thereby significantly improving the air purification effect. Attached Figure Description

Detailed Implementation

[0027] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. The technical methods of the present invention will be further described, but the present invention is not limited to these embodiments.

[0028] like Figures 1-3 As shown, this utility model provides an air purifier with an easy-to-install and remove filter, comprising:

[0029] The air purifier body 100 has an air inlet chamber and an air outlet chamber, which are connected by a connecting port 1211. The top of the air inlet chamber is set as an open port to facilitate the installation and removal of the filter 110.

[0030] The filter 110 has a closed structure. The filter 110 can be vertically installed into or removed from the air inlet cavity through the open opening along its axis. When the filter 110 is installed in the air inlet cavity, it completely covers the connecting opening 1211, ensuring that all air entering the air purifier must be filtered by the filter 110.

[0031] It should be noted that most existing products adopt a rear-mounted or side-opening filter compartment design. Users need to open the cover, release the buckle or twist the fastener to remove the filter 110. Not only is disassembly troublesome, but the disassembly path of the filter 110 requires the user to come into close contact with the surface of the filter 110. Especially in the narrow filter compartment, hands or clothing can easily touch the contaminants on the edge of the filter 110.

[0032] In contrast, the air purifier provided in this embodiment allows users to directly install and remove the filter 110 vertically through the open port without having to go through complicated disassembly steps, which greatly simplifies the replacement process. In addition, this disassembly method can prevent the user's clothes from getting dirty and improve the user experience.

[0033] Preferably, the air inlet chamber and the air outlet chamber are located on the upper and lower layers of the air purifier body 100, respectively. Since the filter 110 is vertically inserted or removed through the open opening at the top of the air inlet chamber, setting the air inlet chamber on the upper layer not only makes it convenient for users to replace the filter 110, but also ensures that the overall aesthetics of the device are not affected.

[0034] The structural design of the air purifier body 100 is described below:

[0035] The air purifier body 100 includes an air outlet base 120, an air inlet filter 130, and an air outlet filter 140, specifically:

[0036] 1. Air outlet base 120:

[0037] The air outlet base 120 provides an installation platform, the air inlet mesh 130 is installed on the top of the air outlet base 120 and is arranged around the edge of the air outlet base 120, and the air outlet mesh 140 is arranged around the outer peripheral surface of the air outlet base 120.

[0038] II. Air intake network 130:

[0039] The air inlet mesh 130 is designed as a cylindrical structure that runs vertically through the top and bottom. The inner cavity formed by the air inlet mesh 130 itself is the air inlet cavity. The top opening of the air inlet mesh 130 forms an open opening for vertical insertion or removal of the filter mesh 110. When disassembling or assembling the filter mesh 110, it is only necessary to vertically remove the filter mesh 110 from the air inlet mesh 130 or insert it inward. The entire disassembly and assembly process is simpler and more convenient.

[0040] In addition, the surface of the air inlet mesh 130 is evenly distributed with mesh holes to form an air inlet. When the filter 110 is installed, air enters the air inlet cavity from all directions along the air inlet mesh 130. The top surface of the air outlet base 120 is provided with a partition plate 121, and the connecting port 1211 is opened on the partition plate 121. After the filter 110 is installed in place, its bottom surface completely covers the connecting port 1211.

[0041] III. Ventilation Net 140:

[0042] The air outlet net 140 is designed as a cylindrical structure that runs vertically through the top and bottom. The inner cavity of the air outlet net 140 and the air outlet base 120 are connected to form an air outlet cavity. The purified air enters the air outlet cavity and is then discharged outward from the air outlet net 140.

[0043] Since the air outlet net 140 is set around the outer periphery of the air outlet base 120, and the surface of the air outlet net 140 is evenly distributed with mesh holes to form an air outlet, the purified air can be discharged in all directions in 360°, thereby achieving a more uniform air distribution, avoiding the problem that the air quality in some areas is significantly better than that in other areas, and improving the overall comfort of the environment.

[0044] The complete air purifier unit is formed by the air outlet base 120, air inlet mesh 130, air outlet mesh 140, and filter 110. After air enters the air inlet cavity through the air inlet mesh 130, it enters the inner cavity of the filter 110 from various sides, achieving the first filtration. Then, it enters the air outlet cavity from the bottom surface of the filter 110 through the connecting port 1211. During this process, the air that has been filtered once passes through the filter 110 again and achieves the second filtration. This dual filtration mechanism ensures that even tiny particles can be effectively captured, thereby significantly improving the air purification effect.

[0045] In addition, the air purifier's air inlet and outlet are both located on the outer circumference of the entire unit, enabling 360° circumferential air intake and exhaust. This design greatly improves the efficiency of air intake and exhaust, ensuring that the air purifier can quickly process air over a wider range. At the same time, through a dual filtration mechanism, it provides cleaner air output, meeting the needs of scenarios with high air quality requirements.

[0046] Furthermore, the top of the filter 110 is provided with a top plate 111, and the top plate 111 is provided with a handle 1111. When disassembling the filter 110, it can be easily disassembled by simply pulling the filter 110 upwards through the handle 1111. This vertical pull-out method avoids the complicated disassembly steps of traditional air purifiers, such as opening the cover and releasing the clips, which greatly simplifies the maintenance process and also avoids the opportunity for users' clothes to come into direct contact with the dirty filter 110.

[0047] The top plate 111 has a convex positioning flange 1112 on its bottom surface. The top plate 111 is mounted on the air inlet screen 130, and the positioning flange 1112 is nested with the inner wall of the air inlet screen 130 to ensure that the filter screen 110 can be accurately installed on the air inlet screen 130 and remain stable. This reduces the risk of displacement or loosening of the filter screen 110 due to external factors (such as movement, collision, etc.) and ensures the stability and reliability of the equipment during operation.

[0048] To ensure the sealing performance between the top plate 111 and the air inlet screen 130, a sealing ring (not shown in the figure) can be set on the outer peripheral surface of the positioning flange 1112 to prevent air leakage and ensure that the air entering the air inlet cavity is filtered by the filter screen 110 before being output from the air outlet cavity.

[0049] Preferably, the air outlet base 120 is equipped with a fan wheel 122, which is driven to rotate by a motor 123. When the motor 123 starts, it drives the fan wheel 122 to rotate at high speed, generating a strong suction force to draw unpurified outside air from all around the air purifier (through the air inlet mesh 130) into the air inlet cavity. Subsequently, this air is guided through the filter mesh 110 for filtration, and finally discharged as purified air through the mesh on the air outlet mesh 140.

[0050] The presence of the impeller 122 greatly enhances the speed and range of air circulation, enabling the air purifier to process more air in a shorter time and improve overall purification efficiency.
