Description

Technical Field

[0001] This utility model relates to the field of air purifiers, specifically an air purifier with an easy-to-replace filter element. Background Technology

[0002] With the rapid development of industrialization and urbanization, air quality has become an increasingly important concern. There are a large number of pollutants in the air, such as dust, pollen, smoke, chemical pollutants (including volatile organic compounds such as formaldehyde and benzene) and microorganisms (bacteria, viruses, etc.). These pollutants can cause many harms to human health, such as respiratory diseases, allergic reactions, and cardiovascular diseases. In order to improve indoor air quality, air purifiers have become an essential device for many homes and offices.

[0003] In the field of product design, the concept of human-centered design is receiving increasing attention. Consumers have higher requirements for the ease of use and convenience of products. For devices like air purifiers that require regular maintenance (mainly filter replacement), users hope to be able to complete the filter replacement operation in a simple and quick way. The rapid development of smart home technology has also provided technical support for the improvement of air purifiers. By integrating smart sensors and communication modules into air purifiers, real-time monitoring and reminders of filter life can be achieved. By using micro-dust sensors to monitor changes in air quality and combining the filter's usage time and filtration efficiency, the remaining life of the filter can be accurately calculated, and the information can be sent to the user's mobile application to remind the user to replace the filter in time.

[0004] However, most air purifiers at present have relatively troublesome filter replacement, which cannot effectively reduce the maintenance cost of filter replacement. They require professional tools or complicated operation procedures, which increases the labor cost of filter replacement. As a result, users cannot replace the filter in time, and the air purifier is always in poor working condition. The equipment is damaged due to the filter not being replaced for a long time, thus reducing the service life of the equipment. Therefore, we propose an air purifier with easy filter replacement.

[0023] 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.

[0024] Please see Figure 1-4 This utility model provides a technical solution;

[0025] An air purifier with easy filter replacement includes an air purifier body 1 and a filter element 6. The air purifier body 1 has an internal retraction device and a sliding device. The filter element 6 has an external filter element fixing device. The air purifier body 1 serves as the outer shell and support structure of the entire device, housing and protecting the internal retraction device, sliding device, and filter element 6, providing a stable environment for their normal operation. The filter element 6 is the core component for achieving air purification, responsible for filtering pollutants in the air. The retraction device and sliding device work together to facilitate the installation, disassembly, and replacement of the filter element 6. The filter element fixing device securely fixes the filter element 6 in a suitable position, ensuring that the filter element 6 will not loosen or shift during air purifier operation, thereby guaranteeing the stability and reliability of the air purification effect.

[0026] Furthermore, the retraction device includes a placement slot 2, a fixing plate 7, retraction rods 8, and a limiting slot 9. The air purifier body 1 has a placement slot 2 inside, and a fixing plate 7 is fixedly installed inside the placement slot 2. Two symmetrical retraction rods 8 are fixedly connected to the side end of the fixing plate 7. The retraction rods 8 have T-shaped grooves inside. The placement slot 2 provides an installation position for the fixing plate 7, allowing it to be securely fixed inside the air purifier body 1. The fixing plate 7 serves to connect and support the retraction rods 8, ensuring that the retraction rods 8 do not shake or shift during operation. To provide a stable foundation for the subsequent contraction and extension of filter element 6, the retraction rod 8 cooperates with other components through its internal T-groove. When filter element 6 is replaced, the retraction rod 8 extends and retracts along the direction of the T-groove. When filter element 6 needs to be removed, the retraction rod 8 retracts to make room for filter element 6 to move outward. When a new filter element 6 is installed, the retraction rod 8 extends to guide filter element 6 accurately into the working position, ensuring that filter element 6 moves along a predetermined path when entering and exiting the air purifier body 1, preventing filter element 6 from tilting or misaligning, and ensuring a smooth replacement process.

[0027] Furthermore, the sliding device includes a support plate 10, sliders 16, a first rotating shaft 17, a first roller 18, a second roller 19, and a second rotating shaft 20. The support plate 10 is slidably installed within the limiting groove 9. Two symmetrical sliders 16 are fixedly connected to both sides of the support plate 10. Multiple first rollers 18, equidistantly distributed in a straight line, are rotatably connected to the upper and lower ends of the first rollers 18. Multiple first rotating shafts 17, equidistantly distributed in a straight line, are rotatably connected to the side ends of the two sliders 16. Second rollers 20, equidistantly distributed in a straight line, are rotatably connected to the outer sides of the second rotating shafts 20. The support plate 10 slides within the limiting groove 9, and the sliders 16 on both sides connect the support plate 10 to the first roller 18 and the second roller 19. When the filter element 6 needs to be replaced and is pulled by an external force, the support plate 10... The support plate 10 moves smoothly within the limiting groove 9 under the drive of the slider 16, providing basic support and guidance for the sliding of the filter element 6, ensuring that the filter element 6 can move in a straight line. The first roller 18 is rotatably connected to the slider 16 through the first rotating shaft 17. When the filter element 6 fixing device is pulled, the first roller 18 rolls under the action of the first rotating shaft 17, converting the sliding friction between the filter element 6 and the slider 16 into rolling friction, greatly reducing the friction force and making the filter element 6 easier to move. The second roller 19 is connected to the side end of the slider 16 through the second rotating shaft 20. During the movement of the filter element 6, the second roller 19 plays an auxiliary support and rolling role, further enhancing the stability and smoothness of the movement of the filter element 6, ensuring that the filter element 6 can smoothly enter and exit the air purifier body 1, and reducing the difficulty of the user to replace the filter element 6.

[0028] Furthermore, the filter element fixing device includes a mounting plate 4, a shrink plate 11, and a shrink baffle 12. The shrink plate 11 is movably mounted on the top of the support plate 10. The mounting plate 4 is fixedly connected to the top of the shrink plate 11 on the side away from the air purifier body 1, and the shrink baffle 12 is fixedly connected to the top of the shrink plate 11 on the side close to the air purifier body 1. The shrink plate 11 can move on the top of the support plate 10. The mounting plate 4 at its top is used to place the filter element 6 and provide an installation platform for the filter element 6. Under the elastic force of the shrink spring 15, the shrink baffle 12 applies a certain pressure to the filter element 6, making it tightly fit against the mounting plate 4, thereby fixing the filter element 6. When the air purifier is working normally, even if it is affected by external forces such as air flow, the filter element 6 can remain stable, ensuring the normal operation of the air purification process.

[0029] Furthermore, a second retraction rod 14 is fixedly connected to one side of the retraction baffle 12, and a retraction spring 15 is fixedly connected inside the second retraction rod 14. A connecting rod 13 is fixedly connected to the other end of the retraction spring 15, and the other end of the connecting rod 13 is fixedly connected to the side wall of the mounting plate 4. The retraction baffle 12 is connected to the mounting plate 4 through the second retraction rod 14. The retraction spring 15 inside the second retraction rod 14 provides the elastic force required to fix the filter element 6. After replacing the new filter element 6, the filter element fixing device is pushed back to its original position, the retraction spring 15 returns to its original state, and the retraction baffle 12 fixes the filter element 6 again, so that the air purifier can continue to work normally, ensuring the convenience of filter element 6 replacement operation and the continuity of equipment operation.

[0030] Furthermore, the retractable rod 14 is fixedly mounted with a side plate 3 on the side away from the air purifier body 1. A handle 5 is fixedly connected to the side of the side plate 3 away from the air purifier body 1. When the filter element 6 needs to be replaced, the user pulls the handle 5 outward. The handle 5 drives the side plate 3 and the retractable rod 14 to move outward. At this time, the retraction spring 15 is stretched, and the retraction baffle 12 is released from the filter element.

[0031] Working Principle: The placement slot 2 inside the air purifier body 1 provides installation space for other components. The fixing plate 7 is fixedly installed inside the placement slot 2, providing stable support and a foundation for the subsequent installation of the retractable rod 8. Two symmetrical retractable rods 8 are fixedly connected to the side of the fixing plate 7. The T-shaped groove inside the rod has guiding and limiting functions. During the replacement of the filter element 6, the retractable rod 8 can extend and retract along the direction of the T-shaped groove, providing a stable path for the movement of the filter element 6 and ensuring that the filter element 6 will not shift when entering and exiting the air purifier body 1, thus ensuring the accuracy and smoothness of the replacement process. The support plate 10 is slidably installed in the limiting groove 9, and can move linearly under the constraint of the limiting groove 9. Two symmetrical sliders 16 are fixedly connected to both sides of the support plate 10, which establishes a connection between the support plate 10 and rollers 18 and 19. The movement of the sliders 6 drives the rollers to rotate, realizing the smooth sliding of the filter element 6. Multiple rollers 18, which are equidistantly distributed in a straight line and rotatably connected to the sliders 16, are used when the filter element 6 is replaced. The device (operated via the purifier side plate 3 and handle 5 connected to the retractable rod 14) has roller 18 rolling under the action of rotating shaft 17, converting the sliding friction of filter element 6 into rolling friction, thus reducing friction. Roller 19, which is rotatably connected to the side end of slider 16 via rotating shaft 20, also plays an auxiliary supporting and rolling role, further ensuring the stability and smoothness of filter element 6 during sliding, allowing filter element 6 to easily enter and exit the air purifier body 1, facilitating user operation. Retractable plate 11 is movably set at the top of support plate 10, with mounting plate 4 fixedly connected to one side of its top for placing and fixing filter element 6. Retractable baffle 12, fixedly connected to the other side, applies pressure to filter element 6 under the action of retractable spring 15, thus fixing filter element 6. When the air purifier is working normally, retractable baffle 12 fits tightly against filter element 6, preventing filter element 6 from shifting due to airflow and other factors, ensuring air purification effect. Retractable baffle 12 is connected to mounting plate 4 via retractable rod 14, with retractable spring 15 inside retractable rod 14 providing elasticity. When filter element 6 needs to be replaced, pull handle 5 outward. Handle 5 moves the purifier side plate 3 and retractable rod 14 outward, stretching the retractable spring 15. The retractable baffle 12 then loosens its fixation on filter element 6. With the assistance of the sliding device, filter element 6, along with its fixing device, can be easily pulled out of the air purifier body 1 for replacement. After replacing filter element 6, push the filter fixing device back to its original position. The retractable spring 15 returns to its original state, and the retractable baffle 12 fixes filter element 6 again, allowing the air purifier to continue operating normally.
